1999 – 2013 Silverado GM Truck LSX Extreme Upgrade Radiator Package
1999 – 2014 Silverado Chevy Truck Suburban Hummer Escalade 6.0L LSX Upgrade Radiator
If you’re upgrading the LSX motor in your 1999 – 2013 Silverado with a serious blown or turbo motor, you’ll need to upgrade the radiator. Our LSX upgrade radiator is a SERIOUS upgrade to the OEM plastic tank radiator with 1-row of 1-1/14″ tubes.
The foundation of this radiator starts with a massive 34″ wide core with 2-rows of 1-1/4″ tubes setup in a double-pass configuration. This means the coolant makes two passes through the radiator before returning to the engine and boost cooling by almost 20%. After we have a solid foundation, we top if off with 2 KILLER 16″ fans, moving a combined 5000+ CFM of air. It’s enough to almost suck your truck down the road.
How much horsepower can this radiator handle? We don’t know, we haven’t found the limits yet. We have customers making over 1000+ HP with this radiator in full weight trucks with A/C. Our estimation is 1500+ horsepower. You’ll probably find the structural limits of the OEM engine block before you’re truck will make more horsepower than this radiator will handle.
– 2-rows of 1-1/4″ cooling tubes – Cooling for 1000HP and beyond
