Description

Valve springs with larger diameters require retainers to handle the higher pressures developed by the springs. COMP Cams Steel Retainers are the perfect solution to this problem. COMP engineers used 3D CAD with FEA to design retainers with a modern and advanced contoured top profiling for lower stress, increased lift and a reduction in mass. The retainers are CNC-machined to exact tolerances using CAD/Cam software. All COMP retainers use only high-grade SAE 4140 chromemoly Steel with no lead,

Product Overview

Valve springs with larger diameters require retainers to handle the higher pressures developed by the springs. COMP Cams steel retainers are precision machined from 4140 chromemoly steel and finished in black oxide. These precision retainers are specifically designed for positive location when combined with COMP Cams high-quality valve springs. For superior strength and ultimate stability, both 7° and 10° retainers and valve locks are available. Refer to the spring application chart on pages 293-303 for correct retainer part numbers for each COMP Cams valve spring.
