Fleece Performance 01-07 GM Duramax/11-16 GM 2500/3500 Duramax Oil Cooler Adapter Kit

Problem: The original equipment oil cooler adapter relies on a metal gasket on the oil cooler that over time is prone to leaking as the cooler flexes. Fix: The Fleece Performance oil cooler adapter utilizes an integral square cut seal ring on the oil cooler mating surface in place of the leak prone gasket to provide a superior seal. Slotted mounting holes on one end allow for easier installation. Recommended Cross Sell Skus - FPE-DMAX-CBOP
