COMP Cams steel retainers for GM Duramax are precision CNC‑machined from SAE 4140 chromemoly steel and black‑oxided for durability. Their contoured top profile reduces stress while increasing lift and lowering mass; this 7° retainer is designed specifically for 26113/26125 beehive springs used on GM 6.6L Duramax applications and supports larger spring diameters and higher spring pressures.
