Straub 346-1371 Rocker Arm Trunnion Kit for LS1/LS2/LS3 with 1.7 Ratio Rockers

The Straub 346-1371 Rocker Arm Trunnion Kit is engineered to upgrade and strengthen the rocker arm assembly on GM LS1, LS2, and LS3 engines equipped with 1.7 ratio rocker arms. This precision-manufactured kit addresses the common weak point in factory LS rocker arm systems by replacing the stock needle bearing trunnions with heavy-duty components designed for high-performance and racing applications.

Key Features:

• Direct replacement trunnion upgrade for LS1, LS2, and LS3 engines with 1.7 ratio rockers
• Eliminates needle bearing failures common in high-RPM and high-spring-pressure applications
• Precision-machined components for improved durability and reliability
• Reduces friction and wear on rocker arm pivot points
• Ideal for performance street engines, race motors, and high-lift camshaft installations
• Compatible with aftermarket 1.7 ratio rocker arms

This trunnion upgrade kit is essential for engine builders looking to prevent rocker arm failure in demanding applications. The improved bearing design handles higher valve spring pressures and sustained high-RPM operation better than factory components, making it a smart upgrade for boosted applications, aggressive camshafts, and racing engines where reliability is critical.
