Why choose the RacingDiffs LSD conversion kit over cheap alternatives?
Uncompromising material quality:
Our discs are manufactured from the highest quality tool steel, heat-treated and nitrided for maximum wear resistance. We include friction discs between the discs and the planetary gears, made from the same material as our LSD clutch discs. This design eliminates the issue of metal shavings often found in cheap LSD kits like Phantom Grip.
Maximized performance:
Our progressive LSD conversion kit incorporates the design principles of ZF-style LSD units and ramp angles, providing low preload without sacrificing progressive locking capability. This means your vehicle will behave like an open differential in slow corners and city driving, but will transfer torque to both drive wheels under load (at high RPM). Dynamic locking thanks to ramp angles, combined with high-load springs, ensures optimal performance.
Key features:
Advanced design: Achieves progressive locking with low preload for superior handling.
Durability: Made from high-quality tool steel, heat-treated and nitrided for exceptional wear resistance.
Improved traction: Eliminates one-wheel peel and improves grip in various driving conditions.
Installation: The kit includes all necessary parts for installation, making it easy to upgrade your differential.
Upgrade your Mazda's differential with RacingDiffs and experience maximum performance and reliability. Order now and transform your driving experience!
