LS Performance Trunnion Kit

LS1, LS2, L76/L77, LS3/L98, LS6, LSA and LS7

Proflow Trunnion Kit is engineered to eliminate one of the most common weak links in factory rocker arm systems—OEM needle-bearing trunnions. When RPM climbs and spring pressures increase, stock components can fail. These performance trunnion upgrade delivers the strength, durability, and confidence serious engine builders demand.

Designed for high-performance street and race applications, this kit replaces factory needle bearings with a premium bronze bushing system and heavy-duty trunnions for superior load distribution and long-term reliability
