Product Description
Michigan Motorsports LS1 Rocker Arms with Trunnion Bearings Professionally Installed & Includes Michigan Motorsports 7.400" Long 5/16" Chromoly .080 Wall Pushrods
These Performance LS1 Intake Rocker Arms feature 16 Straight style rocker arms used on Cathedral Port Heads
When changing Rocker Arms it is a perfect time to install new chromoly pushrods.
New LS1 Rocker Arms have been disassembled and new Trunnion Bearings were professionally installed
Include new LS1 specific bolts for installation.
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 LS1 rocker arms and new LS rocker arm retro-fit trunion kit that replaces the cage-less, loose OEM needle bearings and powdered metal trunion with a premium 8620 steel alloy trunion and caged roller bearings for added durability. The new design from utilizes caged roller bearings that greatly reduce the possibility of the bearing failure experienced with stock LS needle bearings, which can send loose needles throughout the engine upon failure.
This kit includes:
- (16) New LS1 Series Rocker Arms
- (16) Rocker arm trunnions- LS1-type retrofit
- (32) Rocker arm bearings- LS1-type retrofit
- (32) Rocker arm retaining rings- LS1-type retrofit
- (16) Bolts for LS1 trunnion kit
Installation:
- Install the upgraded rocker arms to the cylinder heads using the new socket head cap screws supplied. Be sure to rotate the trunion so that the flat recess side of the trunion's center hole faces upward (the socket head cap screw must seat against this recessed flat side of the hole). Tighten the cap screw to a value of 22 ft-lbs, following the OE installation procedure.
