SuperPro SPF2582K Rear Differential Pinion Mount Bushings for Nissan S14/S15/R32

Vehicle Fitment

• 1995-1998 Nissan 240SX / 200SX (S14 chassis, R200 differential)
• 1999-2002 Nissan Silvia S15 / 200SX (JDM, R200 differential)
• 1989-1994 Nissan Skyline R32 GTS-t / GT-R (R200 differential)

Fitment Notes

• This bushing is fitted to the R200 differential housing's pinion mount rather than being specific to one chassis, which is why it's shared across multiple Nissan S-chassis and Skyline applications that use the same differential
• Confirm your vehicle uses the R200 differential before ordering
• Original inner tube is reused - this kit does not include a replacement tube for that position
• I found consistent confirmation for S14, S15, and R32 fitment across independent sources, but could not verify S13 (1989-1994 240SX) fitment specifically, so it's not included here - confirm with SuperPro or a fitment lookup if you have an S13

Features

• Premium polyurethane construction resists heat, oil, and weather-related degradation far better than factory rubber
• Tightens the differential-to-mount connection for a more direct, flex-free power delivery
• Improves throttle response and launch feel by reducing driveline movement under load
• Helps maintain consistent drivetrain alignment over time
• Provides a stiffness level between factory rubber and a solid differential mount, balancing performance with some vibration dampening
• Suitable for street, drift, and track applications
• Covered by SuperPro's lifetime warranty with no exclusions for off-road, track, or competition use

Specifications

• Fitting Position: Rear Differential, Pinion Mount
• Bushing Material: Polyurethane
• Bush Outer Diameter: 49.5mm
• Warranty: Lifetime (no exclusions for off-road/track/competition use)

Included Components

• 4x Polyurethane Bushings
• 2x Washers (for steel and/or polyurethane use)

Product Description

The differential pinion mount on Nissan's S-chassis and Skyline platforms uses a rubber bushing to isolate the R200 differential from the chassis while still allowing it to transmit power cleanly. As that rubber ages, it softens and lets the differential shift under acceleration and braking loads, which shows up as inconsistent throttle response, wheel hop under hard launches, and a generally looser feel through the drivetrain. The SuperPro SPF2582K replaces this bushing with a polyurethane design built to resist that kind of flex.

Because the part is defined by the R200 differential rather than a single body style, it applies across the S14 240SX, JDM S15 Silvia, and R32 Skyline GTS-t/GT-R - any platform running that differential housing shares the same pinion mount bushing. The kit reuses the original inner tube, so this is a bushing-and-washer replacement rather than a full hardware overhaul.

This kit suits drift, track, and street-driven S-chassis or Skyline owners looking to tighten up a drivetrain that's developed play from worn factory rubber, particularly on cars used for hard launches or repeated on-throttle/off-throttle transitions. It's commonly installed alongside other rear subframe and differential mount bushings for a complete rear-end refresh.
