Worth The Extra Money 0 people found this helpfulHuge difference in the sound once installed. Don’t be fooled by cheaper variations DK Custom product is tapered, variations are belled that are almost impossible to seat fully. Witnessed first hand the difference in product… Worth the extra money!!

Excellent quality and easy install 0 people found this helpfulEasy install, they work as advertised. I installed them on my 2001 FLH several years ago. Just installed them on a 2006 FLH for a friend. He's very happy with the quietness now.

They work as advertised 0 people found this helpfulHave installed 2 sets of these and they do exactly what they claim to do. This is the first “accessory “ that I bought for my second Harley.

Should have purchased as first upgrade. 1 people found this helpfulI could hear the ticking sound over everything before this install, even when wearing a helmet. This took took it away and now all I hear is the exhaust. This install was done in less than an hour on its jiffy stand. Would recommend without question. I installed it on the bike.

Simple solution that Harley ignored 0 people found this helpfulThese worked great. Eliminated that awful tick that Harley claims is normal. My 04 Road King finally sounds solid.

Incredablely simple to a mind numbing problem! 0 people found this helpfulI have a 1999 electra glide Ultra Classic. It was making so much noise out of the top of the engine it was driving me insane. Then I found these and the change is night and day! She is so quite that I can now hear the air intake! No more ticking and rattling.

Unfortunately for me. None of the 4 bolt displayed the circular patterns. 0 people found this helpfulFinally got the time to install them. YouTube community made the install easy. Unfortunately for me. None of the 4 bolt displayed the circular patterns. All 4 were clean. This mean my noise problem will probably be still there. Will update when weather allows me to ride.

Great product! 1 people found this helpfulDid some research on how to quiet down the engine, found this product and decided to give it a try, price was very cheap. Installed kit when I had engine apart for a big bore kit. Well worth the money is all I have to say! After riding my bike hard getting it very hot the engine had little to no noise! Very satisfied
-
Great product 1 people found this helpfulNo more clickey clackey b.s between 2000 & 3000 RPM on my 103" ultra. Easy install just like it should be.

Miracle lockers 1 people found this helpfulI realyy had a bad tick tick sound betwen 2000 and 3000 rpm, those solve all my worries
-
Genius product 0 people found this helpfulThese Rocker Lockers worked fantastic on my Streetglide 103” twin cam. Very easy and straightforward installation instructions and did exactly what they advertised. No slop on the shaft and eliminated the noise from the rocker arms.
-
Simple and effective 0 people found this helpfulFirst off these are easier to install than they look judging by the instructions and videos. Seriously. They’re pretty easy, if you can change your oil, you can install these. And they work! Before my bike was pretty clattery like an old Diesel engine from 2000-2800RPM so cruising at low speeds (like the first 3 gears) was annoying. Upon install I could easily see the witness marks on my rocker hold down bolts plain as day. But now it’s much quieter! Still Have a very light valvetrain noise, which I would consider normal.
-
Best thing I ever did 0 people found this helpfulI bought these when I had my sportster and never got around to putting them in. Fast forward to now and a different bike I ordered them again and I can't believe how simple it was from start to finish. Would highly recommend putting them in. I noticed before the lockers coming in to my neighborhood how much lace train noise now after I put them in what a huge difference.
-
Made by bikers for bikers! 1 people found this helpfulMore than the awesome quality, I’d like to point out the excellent customer service DK provides. Have yet to install the rocker lockers, but the instructions & video resources they provide are top notch. Great to buy a quality USA made product from fellow bikers who understand the value of great customer service!
-
Great service 0 people found this helpfulParts came quick and looked great! i haven't had a chance to install them but i know it will be awesome!
-
GREAT PRODUCT 0 people found this helpfulI’ve never left a review for anything I’ve ever purchased but just installed these on 2010 road glide. You could hear the top end over the 4 inch rinehart dual exhaust, after installation which took literally 1 1/2 hours, no top end noise whatsoever!!!! This product does what it says it does!!!
-
Awesome product 0 people found this helpfulRocker Lockers do exactly what the name implies. Locks the rocker shafts and gets rid of the annoying tapping sound. As a diesel mechanic of over 25+ years,engine noises that i cant put my finger on,drives me crazy.When i can accross the youtube video of before Rocker Lockers and after,there was a noticeable reduction in noise. I knew at that very moment i was ordering a set for my 2000 Road King. I couldnt be happier! I encourage every Harley owner to order a set,you wont be disappointed.
-
Damn fine product 0 people found this helpfulHave put these in both of my baggers does what they say cuts back the tic tic noise alot I've got big cam motors so there still drivetrain noise but nothin like it was......would definitely recommend .......thanx pirate
-
Awesome!!! I can’t believe I waited this long.... 0 people found this helpfulI had to address a lower rocker box leak so I figured while I’m in there. Like everything else with DK Custom Products it was a quality product with good instructions and packaging that works. This is a must do mod. Too easy. Don’t buy the Chinese copies garbage.
-

Awesome 0 people found this helpfulOrdered rocker lockers and had them in hand in four days. Install took me three hours total they took care of almost all the chatter in the top end. Very satisfied!
-
We Will See 0 people found this helpfulInstalled product along with a cam swap. The rocker lockers installed easily and still allowed rockers to work as they should. Bike getting tuned with new cam, so I cannot tell you if it reduced top end noise. I do have a warm fuzzy, but that could change.
-
very happy noise is gone! 0 people found this helpfulworked great! easy to install
-
Noise reduction was substantial 0 people found this helpfulOrdered from Canada took 2wks but after install was worth it. Instructions were well written for procedure. The noise reduction was very substantial. Bike started right up. Will recommend to all Harley owners.

Rocker lockers for twin cam motors 0 people found this helpfulWill do business with dk custom products In the future good prices fast and friendly service and arrived before the date they quoted would recommend them to all my riding buddy's and anyone needed parts thanks so custom
-
Amazing 0 people found this helpfulSo after hearing this annoying ticking noise I found these on the their website I was a little skeptical at first but after receiving them I was happy I have to taking valve covers off which were not hard to do installing these were very easy. You just have to remember to take your time. After installing them putting motorcycle back together remember to put new gaskets. The bike has never been so quiet that annoying ticking noise has been officially gone and I could not be more happier. Once you decide to buy this product and install it you would notice a night and day difference it's crazy how such a simple product can make the world of a difference. Thank you again DK customs for your amazing product.

5 start service and product 0 people found this helpfulhad a customers bike that had that annoying tick after we replaced the tappets (wouldn't pump up), and cam chain tensioners( very loose). we ordered the Rocker Lockers and from the start they were a very easy company to work with. the order went smooth and i was also kept in the loop by email. parts arrived fast and there was zero headache dealing with DK custom Products. i will definitely be using them in the future

Very effective way to eliminate the play at the rocker shafts, simplicity at its finest! 0 people found this helpfulAfter completing a top-end overhaul on my '13 FLHTK, The rocker lockers were a no-brainer! The bike has 60k plus miles on it and it showed minimal witness marks on the bolts. Just for the garage mechs out there, I'm currently running chain drive w/24T frnt. & 55T rear sprockets (love it), Baker all-up shift drum, Pingel electric shifter, Andrews 54H cams, S&S quickee p/r's, S&S roller rockers, reworked heads by Revolution Performance, kept the stock 103 bore & stroke but honed & repl. rings, Thundermax wave tuner. Latest additions were the external breather & floor board extensions from DK customs. Keep up the good work guys!

Smart Solution 0 people found this helpfulClever idea and well executed solution that really does what they claim. Made a huge difference...
-
Great Product 0 people found this helpfulInstall was easy. Customer service (needed due to my screw up) even better - and they didn't mock me even though I deserved it! Go buy the damn thing already. I can't wait to fire up my scoot and NOT hear the ticking noise.
-
Rocker locker install 0 people found this helpfulEasy install, reduced top end noise significantly, great product
-
1997 1200 Sportster 0 people found this helpfulThe rocker lockers have made a big difference in my top end tick. I would say it's about 90% tick free.. Best money spent...
-
Have not installed yet. 0 people found this helpfulReceived as a gift, have not installed yet. Purchase and shipping were great.
-
Awesome service 0 people found this helpfulThanks for shipping your Rocker Lockers all the way to Toronto for me DK Customs. Great service and can't wait to get these installed over the cold winter months!
-
Excellent Product 0 people found this helpfulWe've installed several sets in twin cam engines for ourselves and customers. Excellent product which we now inventory in our shop. For best result, shim your rockers end play as well. We've found around 0.005" end play and a set of rocker lockers takes away ALL the top end noise. Harley allows up to 0.025" end play slop. Add in this and the rattle from the rocker shaft bolt... little wonder why they're so noisy from the OEM.
-
Slightlly quieter 0 people found this helpfulDK Customs is an excellent company. I love their footpegs. Rocker lockers came in quickly and were easy to install. They made my 103 slightly quieter. For 20 some bucks they were worth it. You decide whether you "need" them or not.
-

Cheap cost for the cure 0 people found this helpfulHave yet to install these. And aside from the shipping envelope not being sealed for shipping seems like a good product for the price. Will post a further review when installed.
-
Really no change 0 people found this helpfulInstalled in a 04 Ultra Twin Cam stock. So far I am very disappointed in product, Did not change my valve noise hardly at all, especially in the the common noise range, from 2000 to 3000 RPM range. Riden approx 200 mi since install
-
Great product for an awesome price. 0 people found this helpfulGetting them from the website was easy, shipping was fast, put em in during an engine build on a 2012 FLHX and they worked like a champ! Thanks guys.
-
these things are great 0 people found this helpfulthey work awesome so much quieter a little word to the wise spend an extra 20 and buy new rocker arm bolts I had one snap when I was torqueing it down lucky left enough to get it out easy.
-
Great solution and easy fit 0 people found this helpfulVery quick delivery to the UK, so easy to fit. Great solution..
-
Great top end fix! 0 people found this helpfulThis is coming from a Harley tech, Best easy way to fix that death rattle.
-
2014 Street Glide 0 people found this helpfulI bought this kit cause I heard great reviews and I was changing out the pushrods and lifters. Install was quick and easy. I notice a difference right away when I started the bike. Would recommend this to anyone.
-

Great product 0 people found this helpfulMy 07 ultra classic was making horrible noise from the rockers now that I've installed the RockerLockers so nice and quiet best $20 I've ever spent
-
Rocker Lockers Rock! Quietly 0 people found this helpfulMy 05 twin cam rattled like bbs in a tin can! After a fairly simple and short install of Rocker Lockers I had less valve train noise than any Harley I've heard! Quote from my father "Are you sure its a Harley?" Recommending to everyone I talk to! Cant say enough. Great product that performs exactly as claimed. Dk Customs delivered fast at a great price! Not much to the kit but worth 10 times the price once you see/hear what it does! Thanks DC Customs, and thanks Rocker Lockers! !
-
Worth it 0 people found this helpfulEasy to install order was very fast happy with the product and will be ordering from you guys again
-
so simple, so good 0 people found this helpfulWe've put them in several bikes and it took care of a very annoying situation and saved much direro.. It's so simple but rocker lockers do the trick. Thank you very much.
-
So simple yet massive problem solver 0 people found this helpfulI couldnt beleive how much noise there wasnt any more after the install of rocker lockers. Have a couple guys that have complained about the noise they have and i told them about rocker lockers.
-
Excellent Product 0 people found this helpfulI am very pleased with the product. I was taking the top end apart on the bike and it only made sense to install these to quiet down the rockers. It was a super easy instal on or off the bike and I totally recommend these to anyone that would rather hear their exhaust than the ticking from the top end. I would suggest that 1 or 2 extra sleeves be added to the package in the unforeseen event that one gets bent or if you have to replace one because you are replacing a rocker. Over all awesome product and I recommend it to anyone that wants to hear the sweet sound of the engine.
-
Sounds like a Honda 0 people found this helpfulThe good: Very easy install and the sewing machine noise from the valvetrain is completely gone. The bad (not really): Now the knocking sound through the intake due to reversion after installing new cams is more noticable. I would recommend this $15 fix to anyone. You don't even have to be mechanically inclined to install them. I performed the on-bike installation and it only took about 45 minutes from start to finish. I just ordered a second set for my buddy's bike.
-
Excellent product and service! 0 people found this helpfulI was very pleased with the service I received, knowledgeable staff answered my call and questions without hesitation. The Rocker Lockers were very easy to install, all parts fit perfectly, and the results were immediate, no l more annoying ticking! I am ordering 3 more sets for friends, I highly recommend this product.
-
No movement 0 people found this helpfulReally bought these not so much for ticking, but more fore precision alignment of rockers on valves. The less noise is just an added plus!
-
Running a 120R in my street glide 0 people found this helpfulHad that annoying tick so I changed to roller rockers with adjustable pushrods. Ticking still present, then changed to S&S lifters still had that ticking sound. Then about to pull the top end apart to replace the small end bushes when a friend told me about rocker lockers. After installing them the ticking disappeared, I highly recommend to all Harley riders to invest in a set for there bike. Great product.
-
Great product 0 people found this helpfulNoticed a difference right away. Even more when the bike is warmed up. Going to tell everyone about this product.
-
Awesome 0 people found this helpfulJust finished installing this kit on a 2014 limited, as soon as it fired up you could hear the difference. Easy to install on the twin cooled 103.
-
Great product 0 people found this helpfulI have a 2013 Street Glide with a 103 ci I started hearing tapping around 10k miles I didn't realize how loud it was until I installed Rocker lockers, What a difference it made. It is so quiet now. It was easy to install, ( if you have a little mechanical ability) and follow your service manual. I would encourage anyone with twin cam to buy the kit.
