Show original supplier description
The Nismo GT LSD Pro is a 1.5-way limited-slip differential engineered for versatility, balancing the demands of daily city driving with the increased performance needs of track days and autocross events. Its robust construction features a four-pinion gear design, offering superior strength and durability over standard two-pinion differentials. This comprehensive kit includes everything required for a seamless installation: LSD oil, side bearings, oil seals, cover gaskets, ring gear bolts, and side flanges. The initial torque is pre-set to an optimal setting for each specific vehicle application, ensuring immediate performance benefits without the need for further tuning. While the primary focus is on 1.5-way operation for improved acceleration lock, the plate type allows for conversion to a 2-way LSD. A 1.5-way differential provides stronger lock during acceleration than deceleration, making it particularly adept for gymkhana-style racing, offering a significant change in behavior between the two states. This unit is specifically designed for various Nissan S13, S14, S15 Silvia, 180SX/200SX models, and R33 Skyline GTS models with A/T RB25DE engines produced around January 1996. Compatibility notes indicate potential variations based on engine or transmission changes, advising consultation of chassis number, diff ratio, and rear driveshaft bolt type for certainty.
