This custom aluminum radiator is designed to drop into your FJ4X factory mounting location. This utilizes a 16” SPAL brushless variable speed fan with a built-in fan controller and all wiring. This fan runs standalone and does not need any input from the GM computer. It runs on low speed when the minimum coolant temperature is reached and ramps up as temp increases or if triggered by the AC compressor input.

These are made with LS-size inlet & outlet, a steam port fitting, drain petcock, and can include AN bungs for a transmission cooler (leave comment in checkout). These are custom built one at a time to our specs by skilled craftsmen here in the U.S.

These are made to order, with a 1-2 week lead time. Shipping is included to the lower 48. Stock mounting hardware not included. Radiators ship as bare aluminum but tanks/sides can be painted or powder coated for appearance before installation.

Update 8/12 - current manufacturing lead times are approximately 3 weeks.
