The Speedmaster Shaft Mount Rocker Arm Bridge Block Shim .040 Kit (PCE257.1002) is a precision engine component designed for rocker arm assembly and valve train configuration. This shim kit provides exact thickness compensation (.040 inch) to ensure proper alignment and clearance in shaft-mounted rocker arm systems, critical for maintaining accurate valve lift and engine performance.
This bridge block shim is engineered for applications requiring precise valve train geometry and preload adjustment. The .040 thickness specification allows technicians and engine builders to achieve correct rocker arm height, minimize valve train noise, and optimize engine operation. Compatible with shaft-mount rocker arm assemblies, this kit supports both stock and performance engine builds where precise shim stacking is essential for reliability and efficiency.
