Should have purchased as first upgrade. Review by Jake
I 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. (Posted on 7/20/2022)

Incredablely simple to a mind numbing problem! Review by Tim
I 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. (Posted on 6/13/2022)

Unfortunately for me. None of the 4 bolt displayed the circular patterns. Review by Normand
Finally 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! Review by Tim
Did 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 (Posted on 7/20/2021)

Genius product Review by Jamie M
These 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. (Posted on 5/19/2021)

Simple and effective Review by Drew
First 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 Review by Breakinoutike
I 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. (Posted on 4/20/2021)

I’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 Review by Don
Rocker 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. (Posted on 11/4/2020)

Amazing Review by Paco
So 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. (Posted on 6/1/2020)

Very effective way to eliminate the play at the rocker shafts, simplicity at its finest! Review by Hose
After 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! (Posted on 5/20/2020)

Excellent Product Review by Julio
We'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. (Posted on 9/24/2019)

DK 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. (Posted on 8/27/2019)

Rocker Lockers Rock! Quietly Review by Mohawk Matt
My 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! ! (Posted on 4/23/2019)

Excellent Product Review by Dan
I 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 Review by Sarge4life
The 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. (Posted on 2/24/2019)

Running a 120R in my street glide Review by Doug (West Aust)
Had 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. (Posted on 7/14/2018)

Great product Review by Jet dragger
I 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.
