Transform Your Datsun's Differential with Racing Diffs Progressive LSD Conversion Set Say goodbye to one-wheel spin and experience superior grip with our Progressive LSD Conversion Set, specifically designed for Datsun models equipped with the R200 differential. This kit transforms your standard differential into a clutch-type 25% lock limited slip differential, ensuring enhanced performance and traction. Fitment: Datsun 240Z, 260Z, 280Z, 280ZX, 300ZX, Z31 Why Choose Racing Diffs LSD Conversion Set Over Cheap Alternatives? Uncompromised Material Quality: Our plates are crafted from the highest quality tool steel, heat treated and nitrated for maximum wear resistance. We include friction discs between the plates and spider gears, made from the same material as our LSD clutch plates. This design eliminates the metal shavings problem commonly found in cheap LSD kits like Phantom grip. Maximized Performance: Our Progressive LSD Conversion Set incorporates the design principles from ZF plated LSD units with ramp angles, providing a low preload while retaining a progressive lock capability. This means your vehicle will handle like an open differential during slow turns and street driving but will transmit torque to both drive wheels under load (higher revs). The dynamic lock from ramp angles, along with high load springs, ensures optimal performance. Product Highlights: Advanced Design: Achieves a progressive lock with low preload for superior handling. Durability: Constructed from high-quality tool steel, heat-treated, and nitrated for exceptional wear resistance. Enhanced Traction: Eliminates one-wheel spin and improves grip under various driving conditions.
