Michigan Motorsports LS/LT Bronze Bushing Trunnion Upgrade Kit: - Fits all OEM LS Rocker Arms - Replacement Trunnion Kit for LS and LT Engines - Micro-polished hardened shafts with C932 bearing bronze bushings - No small parts to come loose and damage your engine! - Less prone to failure and loads are spread over a wider area!

The bushing design provides superior lubrication to the trunnion while also providing maximum load capability. Our innovative design prevents premature failures caused by the weak O.E. or replacement needle bearings, eliminating the possibility of debris from a bearing failure that can cause severe engine damage. Our special C932 bushing material is bathed in oil via grooves at 2 different locations on the trunnion. These channels constantly feed oil to the bushing surface ensuring proper lubrication. The greater surface of our bushed trunnion will support 300 times more load than a needle bearing trunnion. Our bushing gets more lubrication and has less load applied to it than the bushing in the small end of a connecting rod, giving it a long service life.

Professionally Installed Trunnion Upgrade Kits: - All of our Rocker Arms with trunnion upgrades are professionally installed right here in house. - LS Rocker Arms with Bronze Bushing Style Bearing Trunions Professionally Installed - Included: 16 New LS Rocker Arms with Bushing Style Bearing Trunions Professionally Installed and 16 Alen Head Bolts.

Whether you have a stock LS motor or a highly modified LS motor, replacing your rockers with upgraded Trunion Kit 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. LS Rocker Arms feature our BUSHING TRUNNION KITS. The Bushing bearing operate smoother and can operate at a higher RPM than even the caged bearing style upgrade.
