GKTech Infiniti Nissan Z34 370z/G37 Rear subframe slip-in collars - Solid

The GKTech Solid Rear Subframe Slip-In Collars for the Nissan 370Z (Z34) and Infiniti G37 are a quick, effective way to eliminate subframe movement without the need to fully remove and replace your factory bushings. These solid aluminum collars slip over the OEM subframe bushings, creating a metal-to-metal interface that locks the subframe firmly in place—greatly improving rear-end stability, traction, and suspension response.

Ideal for drift, grip, and high-performance street builds, these collars are a bolt-on solution for drivers looking for solid mount performance without the effort of a full bushing press job.

Key Features:

• Solid Mount Feel Without the Hassle – Slip-in design mimics the rigidity of full solid bushings.

• Reduces Subframe Flex and Movement – Improves suspension geometry consistency under load.

• CNC-Machined 6061-T6 Aluminum – Lightweight, strong, and corrosion-resistant.

• Easy Installation – Installs without removing the subframe; no press tools required.
