Rear Differential Cooler

The Willall Racing WR35DC is a comprehensive rear differential cooler engineered specifically for the R35 GTR, designed to manage high operating temperatures. This system is fully integrated and requires no cutting, shutting, moving, or modification for installation, making it suitable for track-oriented or hard-driven vehicles. The kit includes a 13-row cooler, high-pressure, high-temperature crimped lines, and all necessary hardware. It features a CNC-machined mounting bracket and mounts behind the rear differential before the exhaust system, utilizing existing holes in the factory crossmember. This placement ensures compatibility with any aftermarket exhaust system and benefits from airflow from the underbody transmission air scoop. Thoughtful engineering is evident in features like the new air deflector system that bolts in place of the factory part, providing adequate clearance. Additionally, a 'Jacking Point' adapter is included, allowing the use of the factory jacking point without damaging the cooler system when changing tires. The WR35DC system can be integrated with Willall Racing WR35TC or TC-F transmission coolers, utilizing a 'double pump' loom extension or triggering via the existing transmission temperature thermostat. For systems without these, a manual switch with an indicator light is provided.
