Keep your Transmission and Power Steering fluids cool with the Cooler Combo Kit from Red Rock. This kit keeps the install of both coolers clean and simple. The kit includes a 6 pass heavy duty cooler for the transmission and a 2 pass cooler for the power steering system. Both coolers are significant upgrades from the stock 'style' systems on the JK/JKU.
Originally designed for use when swapping in a Hemi and 545rfe into a 07-11 JK/JKU, but now we have a kit for 12-18 JK/JKUs keeping the 5AW580 transmissions as well.
