Billet Alm. Oil Cooler Adapter GM LS Engines

The Billet Aluminum Oil Cooler Adapter for GM LS Engines from SETRAB is purpose-built for serious LS swappers and high-performance engine builders who demand reliable thermal management in modified applications. This HyperFlow adapter bridges the gap between modern cooling systems and classic engine platforms, making it essential for anyone upgrading carburetor-era vehicles with LS powerplants or optimizing factory LS cooling circuits beyond stock parameters.

Machined from premium billet aluminum and finished in silver anodize, this adapter features 22 mm x 1.50 female inlet and outlet ports that facilitate seamless integration with aftermarket oil cooler lines and sandwich-style cooler fittings. The HyperFlow design minimizes turbulence and pressure drop across the adapter body, critical factors that prevent unwanted heat retention and maintain oil viscosity under sustained high-RPM operation. Billet construction ensures superior durability and eliminates the brittleness associated with cast aluminum adapters, particularly important when engine vibration and thermal cycling stress threaded connections over thousands of miles.

Mechanics and engine builders working on Gen III, Gen IV, or Gen V LS platforms will find this adapter indispensable for custom cooling setups, whether installing remote-mount coolers in tight engine bays or upgrading OEM systems to handle increased boost or fuel load. The standardized 22 mm female ports accept common metric cooling lines and fittings found across European and Japanese performance applications, giving builders maximum flexibility in system design. Each unit is individually inspected and ready for immediate installation—simply thread into the block or sandwich plate and route your cooler lines for optimal oil temperature stability.
