Control heat. Protect the drivetrain. The PEAK cooler kit adds dedicated transmission and power steering cooling to the 2018 to 2024 KGM SsangYong Musso and Rexton automatics, for owners who tow, carry load or drive where heat builds fast: hills, sand, long highway runs and hot weather. It bolts in with purpose made mounts and routing, not a universal kit made to fit.
