Front Lower Compression Arm Rearward Bushing Set

Precision Suspension Restoration for 2003–2009 Nissan 350Z and Infiniti G35

Restore the sharp handling and steering precision of your vehicle with this 2-Piece Front Lower Compression Arm Bushing Set. On the Nissan FM chassis, the compression arm (radius arm) bushings are a critical point of failure. These rearward bushings are responsible for absorbing longitudinal road force; when they tear or leak, it results in vague steering, increased vibration, and audible clunking during braking or cornering.

This set is engineered as a direct-fit replacement for the high-wear outer bushings on the compression arms. By replacing only the bushings rather than the entire aluminum arm assembly, you can restore your suspension's geometry and eliminate tire-wearing "play" while maintaining a cost-effective repair.

Fitment Verification and Vehicle Applications

Installation and Technical Tips

• Hydraulic Press Requirement: These bushings are designed for a high-interference fit within the aluminum compression arm. A hydraulic shop press and the correct driver cups are required for removal and installation. Do not attempt to hammer these bushings into place, as it can damage the arm or the new bushing casing.

• Bushing Orientation: Before pressing out the original bushings, observe the orientation of any gaps or markers on the rubber. To ensure proper suspension articulation, the new bushings should be "clocked" or indexed to match the factory position.

• Tighten at Ride Height: To prevent premature bushing failure, do not perform the final torque of the mounting bolts while the vehicle is on jack stands with the suspension hanging. Lower the car onto its wheels or use a floor jack to load the suspension to its normal ride height before tightening.

• Post-Repair Alignment: Because the compression arm directly influences the caster and toe settings of your front wheels, a professional four-wheel alignment is mandatory after installation to prevent rapid tire wear.
