ROCKOUT rocker shaft inserts

They work

Fast Shipping & worked great.

Easy to install, works good

I built up a motor and used these with the S&S roller rockers that were installed. So far so good. The idea and principle appear to be sound, installation was straight forward and easy, it did eliminate the little bit of wiggle that was in the rocker shafts. It has been a couple years now, and my top end still sounds great!! I have had absolutely no issues at all and that annoying tick tick tick is not there! If you are in teh rocker boxes anyway, take the time to install these little gems, you will not be sorry!

I finally installed these on my 2016 road glide ultra. All i can say is that this product is amazing. Very quiet, dont hear the knock knock sound at start up and at low idle. I wasnt sure if this was going to make a difference. I can now tell you it does. Ive put about 90m miles now with these in and they are still performing well. Who would have thought $15 item could make such a huge iomprovement. Well worth the work, read and follow the instructions, easy to install if your somewhat mechanically minded. Thanks for inventing... great product at a great price!!

I’ll let you know at the end of summer but I like them they did what were supposed to it quieted the top end right down

Worked great-awesome support!

Fast delivery and was as specified.

Product is easy to install and works as advertised.

Great product to remove/reduce valve train noise. Installation was easy, but has the potential for an amateur to screw it up. Should probably contain two extra sleeves instead of one in case a customer accidentally installs a rocker arm backwards.
