ROCKOUT rocker shaft inserts

Works as promised

Came with easy installation instructions. Perfect fit. I cant believe how much quieter the engine is.

perfect fit!

The product does exactly as advertised. Perfect Nothing bad to say

Since the inserts are tapered, they get tighter as you try to draw them into the rocker support. This force causes the inserts to mushroom at the top, preventing them from seating flush into the hole, and preventing the bolt head from sitting flush on top of the support. The metal is too soft. I dont think they need to be tapered, since they cant go anywhere once installed. Not all that impressed with it. Needs more development.

Easier than the instructions to install

Read instructions and Read them again...follow them. Several Q-tips work good for clearing oil from bolt holes. compressed air will spray oil all over you bike. Worked perfect. Nice to be rid of the ticking noise. ROCKOUT and ROCKON

easy to install

Didnt seem to make much of a difference on my twin cam. Many others have said it makes a noticeable difference. I will give a 5 star rating to the developer of this product as he was extremely helpful to me with the install.

I will never go into the top end of a Twin Cam again without installing these! I installed these when I did the top end on my Dyna, including .560 lift cams. The valve train on my Dyna is quieter than stock!
