These COMP Cams steel retainer sets are precision machined from chromemoly steel, black‑oxided, and profiled to reduce stress and mass while supporting increased valve lift. Specifically engineered for 26113/26125 beehive springs used on GM 6.6L Duramax engines, the retainers accommodate larger spring diameters and the higher pressures developed by upgraded valve springs.
