Show original supplier description
The NISMO 38420-RS661 is a limited slip differential (LSD) engineered for performance enhancement in the Nissan 240SX. This component features a robust 4-pinion design, intended to provide enhanced traction and handling characteristics. With a specified breakaway torque of 70 lb-ft, this LSD is designed to distribute power more effectively between the rear wheels, particularly during acceleration and cornering. This leads to improved stability and reduced wheelspin. This particular NISMO LSD is compatible with 1989-1998 Nissan 240SX models. It is crucial to note that this differential is intended for vehicles that *do not* come equipped with an original equipment (OE) limited slip differential from the factory.
