Swapping a LSX radiator into your Jeep can be a lot of parts hunting. When it comes to your cooling system for your Jeep upgrade, that parts hunt ends here. Our radiator/ fan combo is a bolt in to your Jeep and the easy way to upgrade your Jeeps cooling system to handle a V8.

When upgrading to your Jeep to a crossflow radiator for your small block or LSX conversion, there is an important detail most people gloss over. And glossing over this key detail can cause you massive headaches trying to keep your Jeep cool.

Because the Jeep YJ/TJ engine compartment is fairly narrow, there isn’t a lot of room to make a wide crossflow radiator for the Jeeps. As such, most Jeep crossflow radiators are made with an 18″ wide x 19″ high core. For comparison purposes, the core size is in a 68 Chevelle is 28-1/4″ wide x 19″ high. That’s a HUGE difference.

An 18″ wide core with 1″ tubes is barely adequate to cool a SBC motor. To address this, we only build the YJ and TJ radiators with 2-rows of 1-1/4″ tube cores. By using the larger HD cores with 1-1/4″ tubes, your Jeep will stay cool both cruising down the highway or on slow rock climbs where you need it.


– 2 rows of 1-1/4″ tubes for cooling up to 750 LSX horsepower

– 2800 CFM 16″ Electric Fan and Aluminum Shroud

– Precision hand TIG welded

– Billet CNC machined filler neck

– Correct LSX hose connections both on the passenger side with steam vent port

– Lifetime Warranty

Like all of our radiators, it’s made in the USA. We guarantee you’ll find it’s bad ass and guarantee it to cool your car with ease. And of course our lifetime warranty on everything: radiator and fans. 

For fan control, please use our RH-01 Wiring Harness.
