Tech-53 Rear Subframe Bushing Kit for Nissan 370Z

Tech-53 Rear Subframe Bushing Kit for Nissan 370Z Specifications

The Nissan 350Z, 370Z, Infiniti G35 and G37 share the same rear subframe bushings, which wear out quickly, affecting handling, stability and comfort. Tech-53 has developed a high-performance replacement kit, engineered for a perfect fit and exceptional durability.

This kit combines lightweight yet strong aerospace-grade 6061-T6 aluminum inner sleeves with rigid Delrin bushings that eliminate unwanted flex. Unlike solid aluminum mounts, Delrin offers outstanding stiffness while maintaining a level of comfort — minimizing noise and vibration without compromising performance.

In addition to improving chassis response and rear-end feel, these bushings preserve correct alignment under high loads. Tested on race cars, including drift builds making over 500 wheel horsepower, they’ve proven reliable on both track and street.

Two mounting options:

• Standard fitment: install all components to retain OEM subframe height.
• Raised fitment: omit the upper bushings to raise the subframe by 0.5" (1.27 cm).

Raising the subframe is especially beneficial on lowered vehicles. It helps reduce CV axle angles — extending their lifespan — and corrects suspension arm geometry, enhancing cornering stability.

Kit contents:

• 4x rear subframe bushings in Delrin
• 4x inner sleeves in 6061-T6 aluminum
• 4x upper bushings in 6061-T6 aluminum

Vehicle compatibility:

• Nissan 350Z / 370Z
• Infiniti G35 / G37

Installation tip: Freeze the aluminum sleeves before installation to ease fitment.
