Genuine NISMO Rear A-Arm Set – R32 GT-R / S13 Silvia / 180SX – 55550-RS580
Upgrade the rear suspension of your Nissan with a Genuine NISMO Rear A-Arm Set, designed for compatible R32 Skyline GT-R, HNR32 GTS-4, S13 Silvia and 180SX applications.
Developed as a performance-focused replacement for the original factory rear suspension arms, this genuine NISMO set features reinforced rubber bushes pre-installed, helping reduce unwanted suspension movement and improve rear-end stability under load.
Compared with ageing factory rubber bushes, the uprated NISMO components provide more controlled suspension movement, helping deliver improved rear suspension response, greater consistency during cornering and a more connected driving experience.
Unlike solid-mounted or polyurethane alternatives, NISMO's reinforced rubber construction retains a degree of compliance, offering an excellent balance between performance, comfort and everyday drivability.
Whether you're restoring an R32 GT-R, refreshing the suspension on your S13 Silvia or building a responsive street or track-focused 180SX, genuine NISMO suspension components provide the quality and factory-style fitment expected from Nissan's official motorsport brand.

Why Upgrade to NISMO Reinforced Rear A-Arms?
Factory rear suspension bushes are designed to provide a balance of comfort and handling. However, after decades of use, the original rubber bushes can deteriorate, crack or soften, allowing excessive movement within the rear suspension.
This unwanted movement can contribute to less consistent suspension geometry, reduced steering response from the rear of the vehicle and a less predictable feel during cornering and acceleration.
The NISMO Rear A-Arm Set uses uprated rubber bushes to help control suspension movement more effectively, providing improved stability and responsiveness while retaining the benefits of rubber-mounted suspension components.
For enthusiasts seeking a genuine Nissan Motorsport upgrade without moving to rigid aftermarket arms, this NISMO set offers an excellent combination of performance and factory-style fitment.

Important Installation Information
These arms are designed for compatible factory Nissan rear suspension arrangements.
Factory mounting collars must be reused from the original arms where applicable. Please inspect and retain the required original hardware before installation.
Mounting bolts, nuts and additional suspension hardware are not included.
Installation should be carried out using the correct Nissan workshop procedures and factory torque specifications. A professional wheel alignment is recommended after replacing rear suspension components.
As the NISMO bushes are firmer than standard factory rubber, a slight increase in road feedback or noise, vibration and harshness (NVH) may be noticeable.
