Fleece Performance Oil Cooler Adapter Kit for Select 2001-2019 GM 2500HD/3500HD Duramax (FPE-DMAX-OCADPT)
$99.00
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits select 2001-2019 Chevrolet Silverado and GMC Sierra 2500HD/3500HD models equipped with the Duramax diesel engine.
Eliminate chronic oil leaks at the cooler with the Fleece Performance oil cooler adapter. The original equipment adapter relies on a thin metal gasket that is prone to failure as the cooler flexes during standard operation and thermal cycling. This heavy-duty replacement kit solves the issue by utilizing an integral square-cut seal ring directly on the mating surface, providing a significantly more robust and reliable seal than the factory design.
Engineered for professional installers and DIY enthusiasts alike, this adapter features slotted mounting holes on one end to simplify alignment and reduce installation time. This kit is a direct-fit solution to prevent future maintenance issues and keep your lubrication system secure.
- Replaces leak-prone factory oil cooler adapter
- Integral square-cut seal ring for a superior, leak-free connection
- Slotted mounting holes for easier installation and alignment
- Fits 2001-2019 GM 2500HD and 3500HD Duramax engines
- Manufacturer Part Number: FPE-DMAX-OCADPT
