Whiteline Performance Rear Axle Trailing Arm - Rear Bushing Kit - 350Z / 370Z
W62998
The trailing arm rear bushing sits at the hub end of the trailing arm, it's the point where the arm locates the wheel. When it wears, the rear wheel loses its precise location under load and the whole rear end becomes vague and unpredictable. The Whiteline W62998 replaces both sides with advanced synthetic elastomer that restores control and confidence immediately.
The rear bushing carries the lateral and fore-aft loads closest to the wheel, it's where sloppy geometry is felt most directly. A worn rear trailing arm bushing undermines every other suspension component behind it.
Engineered specifically for the rear axle trailing arm rear position across the 350Z, 370Z, and the full Z/Skyline/Stagea family, this kit covers both sides in a single purchase. Whiteline's synthetic elastomer delivers genuine rigidity under load while remaining compliant enough for daily use, and is backed by a lifetime warranty.

Installation guide
Included
What it does for your car
- Restores precise rear wheel location, eliminates the compliance that causes rear instability
- More planted, confident rear-end feel through corners and under braking
- Eliminates the vagueness that builds up as OEM rubber fatigues over time
- Reduces uneven rear tyre wear caused by trailing arm deflection at the hub end
- Synthetic elastomer is compliant at low loads, firms up under driving 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 shell design for high load-bearing strength and long service life
Installation

Difficulty
DIY — specialist tools needed
Press tool required. Bushing installation requires a press. Whiteline recommends using the WTK001 Press In/Out Kit with the specified sleeves and plates for correct fitment (M12 threaded rod). Professional installation recommended if you don't have access to a press.

• Nissan 350Z Z33 · 2003–2009 (all variants)
• Nissan 370Z Z34 · 2009–2020 (all variants)
• Nissan Z RZ34 · 2022+
• Infiniti G35 · 2002–2007
• Infiniti G37 · 2008–2013
• Nissan Skyline V35 · 2001–2007
• Nissan Skyline V36 · 2006–2015
Pair with W62985 (trailing arm front bushing) for a complete trailing arm rebuild while the arm is already off. Tackling both positions at once saves significant labour time and ensures the entire arm is back to factory spec — or better.
