PEAK Transmission & Power Steering Cooler Kit for KGM Ssangyong Musso & Rexton

Control heat. Protect the drivetrain.

The PEAK Bolt-On Transmission + Power Steering Cooler Kit is the complete cooling solution for Musso and Rexton owners who tow, carry load, or drive in conditions where heat builds fast. It’s built to reduce thermal stress on the automatic transmission and power steering system, using a clean, purpose-fit layout that installs properly — not a universal “make it work” kit.

This kit is designed to keep temperatures stable when it matters most: towing, hills, sand, long highway pulls, and hot climates.

Key Features

• Transmission + Power Steering Cooling (Complete System)
  A combined package designed to manage ATF and power steering heat under load.
• Bolt-On Fitment (No Universal Hacks)

• Heat Management Where It Counts
  Reduces heat soak and helps maintain safer operating temperatures during demanding driving.
• Built for Real-World Use
  Designed around the Musso/Rexton front-end packaging for practical clearance and proper routing.
