Engineered for the Swap
To maximize the performance of your LS Swap, you need a Griffin Dual Pass LS Series Radiator. We have engineered a cross-flow unit with both the inlet and outlet on the passenger side to match LS engine configurations perfectly.
THE STEAM PORT!
Why it matters: One of the most critical aspects of an LS swap is the steam vent system. LS engines are designed with ports on the cylinder heads to release trapped air and steam, preventing hot spots and gasket failure.
The Griffin Solution: Unlike standard radiators, our LS Swap series features an integrated steam port provision (bungs or NPT ports). This allows you to plumb your steam lines correctly without drilling into water pumps or splicing hoses, ensuring your engine cools exactly as intended.
Dual Pass Flow
Coolant passes through the core twice, maximizing heat dissipation.
Passenger Side I/O
Inlet and outlet are both on the passenger side to match LS water pumps.
MegaCool™ Tubing
Featuring exclusive 1.25-inch induction welded tubing for extreme cooling capacity.
American Made
Every Griffin radiator is proudly manufactured in Piedmont, South Carolina.
