PEAK Transmission & Power Steering Cooler Kit for KGM Ssangyong Musso & Rexton
Tired of overheating on long drives or towing heavy loads? Introducing the ultimate solution for your Musso or Rexton—the Peak4x4 Bolt-On Transmission & Power Steering Cooler Kit. Designed to reduce temperatures by up to 30°C on highway drives, this essential upgrade is perfect for anyone planning long trips or hauling extra weight.
Both KGM Musso and Rexton models lack factory-fitted transmission coolers, leading to common issues like limp mode when the transmission overheats. Our cooler kit effectively manages these high temperatures, preventing torque limitations and erratic gear shifts caused by overheating. The bolt-on design fits seamlessly with both standard front-end setups and bullbar configurations, making installation straightforward and efficient.
This kit also includes a dedicated power steering cooler, an added bonus that ensures smoother, more responsive steering, especially under heavy load. By lowering the transmission and power steering temperatures, you’ll extend the service life of both systems, reducing wear and saving on costly maintenance.
Protect your gearbox and enhance driving performance with our Transmission & Power Steering Cooler Kit—a must-have upgrade for long-haul durability and peace of mind.
Please Note: Installation requires approximately 350ml of additional transmission fluid and 100ml of additional power steering fluid.
