Genuine NISMO Rear Differential Mount Bush – R32 R33 R34 GT-R S14 S15 – 55470-RS580
Improve drivetrain response and reduce unwanted differential movement with a Genuine NISMO Reinforced Rear Differential Mount Bush, designed for compatible Nissan Skyline GT-R, Silvia and other Nissan performance vehicle applications.
Developed as a performance-focused replacement for the original factory differential mounting bush, this genuine NISMO component features reinforced, higher-durometer rubber construction to provide increased resistance to differential movement under load.
During acceleration, braking and rapid gear changes, the rear differential is subjected to significant drivetrain forces. Worn or deteriorated mounting bushes can allow excessive movement, contributing to unwanted drivetrain movement, clunks and reduced drivetrain responsiveness.
The NISMO Reinforced Rear Differential Mount Bush helps control this movement, supporting more consistent differential positioning and improved drivetrain response during spirited driving.
Unlike solid differential mounting solutions, NISMO's reinforced rubber construction retains a degree of compliance, providing an excellent balance between increased mounting firmness, everyday drivability and long-term durability.
Whether you're refreshing the rear differential mounts on your Skyline GT-R, rebuilding a compatible NISMO differential mounting assembly or preparing your Silvia for performance street or track use, genuine NISMO bushes offer a quality upgrade over ageing factory rubber components.

Why Upgrade Your Rear Differential Mount Bushes?
The factory differential mounting bushes are designed to support the rear differential while absorbing vibration and drivetrain movement during normal driving.
Over time, the original rubber can deteriorate, crack, soften or separate from its mounting sleeve, allowing excessive movement within the differential mounting assembly.
Common symptoms of worn differential mounting bushes may include:
- Excessive differential movement during acceleration
- Drivetrain clunks when changing gears or applying throttle
- Unwanted movement during rapid throttle transitions
- Cracked, deteriorated or separated rubber bushes
- Reduced drivetrain refinement due to worn mounting components
The NISMO Reinforced Rear Differential Mount Bush provides an uprated rubber replacement designed to better control differential movement while retaining the benefits of rubber-mounted drivetrain components.
This makes it an excellent choice for Nissan enthusiasts seeking improved drivetrain control without moving to completely solid differential mounts.
Quantity Required
This listing includes one (1) genuine NISMO rear differential mount bush only.
Two (2) bushes are required per compatible vehicle for the applicable rear differential mounting arrangement.
If replacing both rear differential mounting bushes, please add a quantity of 2 to your cart.
Additional Parts That May Be Required
Depending on the original differential mounting configuration, additional genuine Nissan components may be required during installation.
- Genuine Nissan Washer – 55482-60U1A – May be required for certain factory bush configurations
These washers are not included with this listing and must be purchased separately if required.
Please check the applicable Nissan or NISMO installation information before ordering to determine whether additional washers or hardware are necessary for your vehicle.
Important Installation Information
This bush requires press-fit installation into a compatible rear differential mounting assembly.
Suitable pressing equipment and correct installation procedures are required to avoid damaging the new bush or its mounting location.
Professional installation is recommended. Inspect the condition of the differential mounting assembly, associated brackets, bolts and washers during replacement.
Follow the applicable Nissan or NISMO workshop procedures and factory torque specifications.
As these bushes are firmer than standard factory rubber, an increase in drivetrain noise, vibration and harshness (NVH) may be noticeable, particularly in modified or performance-focused vehicles.
