Genuine NISMO Differential Mount Bush Kit – 55401-RS590

Genuine NISMO Differential Mount Bush Kit to suit a range of Nissan performance models, including the R33 & R34 Skyline, BNR32, BCNR33 & BNR34 GT-R, and other compatible applications.

Designed as a complete upgrade over the factory differential mounting bushes, this genuine NISMO kit uses reinforced high-durometer rubber to significantly reduce differential movement under acceleration, braking and hard gear changes. The result is improved drivetrain response, more consistent power delivery and enhanced rear-end stability, while maintaining the refinement and durability expected from genuine NISMO components. The kit includes all bushes required to refresh the differential mounting system on one vehicle.

Perfect for suspension refreshes, performance street cars or track-focused builds using genuine NISMO components.
