Whiteline Performance Rear Axle Control Arm Lower Rear - Inner Bushing Kit
W63626
The rear inner bushing on the rear lower control arm governs how the arm pivots under acceleration, braking, and cornering. When it wears out, the rear end loses composure exactly when you need it most. The Whiteline W63626 replaces it with advanced synthetic elastomer engineered to hold geometry precisely through every load condition.
Worn rear lower arm bushings are one of the most common and most overlooked causes of rear instability on the 370Z platform, especially on higher-mileage cars.
Engineered specifically for the rear axle lower control arm rear inner position on the 370Z, G37, and Z RZ34, this kit delivers the hallmark Whiteline balance: compliant enough for comfortable daily use, firm and controlled under hard driving. Backed by a lifetime warranty.

Installation guide
Included
What it does for your car
- Restores rear lower arm pivot geometry, eliminates compliance that causes rear instability
- More consistent, predictable rear-end behaviour under acceleration and braking
- Sharper rear response through corners, less lag between input and reaction
- Reduces uneven rear tyre wear caused by geometry shift under load
- Synthetic elastomer is compliant at low loads, firms up under cornering and braking pressure
- Superior resistance to oil, grease, ozone, and weathering vs OEM rubber
- Internal grease reservoirs for continual self-lubrication, quiet and maintenance-free
- Specially bonded design for high load-bearing strength and long service life

Press tool required. Shell bushings must be pressed in and out. Professional installation is recommended if you don't have access to a hydraulic press and the correct press sleeves.
Fitment
• Nissan 370Z Z34 · 2009–2020 (all variants)
• Nissan Z RZ34 · 2022+
• Infiniti G37 · 2008–2013
Best paired with W63625 (rear lower front inner) for a complete rear lower control arm bushing refresh. Tackle both positions at the same time while the arm is off, saves labour and ensures the whole arm is back to spec. Combine with the Whiteline BNK014 sway bar kit for a full rear handling overhaul.
