Description
Feature:
Whether you have a stock LS motor or a highly modified LS motor, replacing your rockers with a true roller bearing setup is highly recommended. The stock bearings have a tenancy to fail. These rocker arms are a must have for any aggressive heads and cam combo and are the same rockers we utilize on our 1,000 hp Turbo Motor. We utilize LS rocker arms and install new LS1 rocker arm retro-fit trunion kit that replaces the cageless, loose OEM needle bearings and powdered metal trunion with a premium 8620 steel alloy trunion and caged roller bearings for added durability. The caged roller bearings that greatly reduce the possibility of the bearing failure experienced with stock LS1 needle bearings, which can send loose needles throughout the engine upon failure.

Customer Reviews
Smooth operation, noticeable performance bump. Shipped fast.
I haven’t installed yet, but have had no issues with other Michigan Motorsports products in the past. Arrived a day earlier than estimated, we’ll packed and were of the quality described. Have no question they will suit my needs just fine.
These are a great replacement for the factory ones that have been known to fail. This is the third engine we have installed these in and they work very well. Change all of them. Not just the bad ones. You will have to go back in there again. Just get enough to do all 4 cams. It’s worth the effort.
This kit was exactly what I needed for my engine rebuild. The parts are of good quality and the installation was straightforward. My engine runs much smoother now!✌️
