COMP Cams .585" Lift Beehive Valve Spring Kit for 2006–2016 GM 6.6L Duramax (LBZ/LMM/LML/L5P) includes beehive springs, steel retainers, spring seats and valve seals for an easy upgrade. The reduced top diameter accommodates smaller, lighter retainers to cut valve‑train weight; the ovate beehive shape increases dynamic stability and load capacity, helping maintain valve control at elevated RPM and boost.
