GKTech Nissan Z34 370z Diff Brace

The GKTech Differential Brace for the Nissan 370Z (Z34) is designed to reduce wheel hop and rear-end instability by reinforcing the OEM differential mount. The factory diff cover uses only a single bush and stud, which can flex under hard acceleration or aggressive driving—leading to premature wear or even failure. This brace ties the differential directly to the subframe using an existing hole, eliminating excess movement and increasing drivetrain rigidity.

Made from TIG-welded steel and e-coated for corrosion resistance, this is a lightweight, effective solution that takes just minutes to install and makes a noticeable difference in how your car puts power down.

Key Features:

• Reduces Differential Movement – Limits flex and wheel hop during acceleration and shifting.

• Bolt-On Install – Uses existing subframe holes, no drilling or cutting required.

• Durable Construction – TIG-welded steel with e-coated finish for corrosion resistance.

• Quick Installation – Can be installed in under 15 minutes with hand tools.

• Improves Traction & Stability – Ideal for spirited driving, drifting, and track use.
