Why Choose RacingDiffs Over Cheaper Alternatives?

• No Material Compromise: Our kit uses high-quality tool steel, heat-treated and nitrided for superior durability and wear resistance. Unlike cheap alternatives like Phantom Grip, we’ve integrated friction discs between plates and spider gears to prevent the generation of metal shavings, a common issue with lower-grade LSD kits.
• Maximized Performance with Progressive Locking: Designed using ZF LSD technology with Ramp Angles, our kit offers a progressive locking effect under load. You’ll experience smooth street driving, but when revs increase, torque is evenly distributed to both drive wheels for improved grip and performance.

Important Installation Note:

Before installing the kit, inspect the inner surface of the small spider gears. Ensure they are smooth and undamaged from previous use. If necessary, have the gears machined for a perfect fit, preventing premature wear and breakdown.
