GKTech Scion Subaru Toyota FR-S / GR86 / BR-Z chassis Solid diff bushings - Raised 20mm

The GKTech Solid Diff Bushings – Raised 20mm for the Toyota FR-S, GR86, and Subaru BRZ are designed to eliminate drivetrain movement and raise the rear differential by 20mm, optimizing CV axle angles and driveline geometry—especially important for lowered vehicles and track builds.

By replacing the factory rubber diff bushings with CNC-machined solid aluminum units, these bushings offer zero flex, significantly improving power transfer, rear-end stability, and response under load. Raising the differential also helps to reduce axle wear and binding, making it ideal for drift and grip applications alike.

Key Features:

• 20mm Raised Geometry – Lifts the differential for better CV axle alignment on lowered cars.

• Solid Mount Design – Eliminates bushing flex for precise power delivery and consistent rear-end behavior.

• CNC-Machined Billet Aluminum – High-strength and lightweight construction for motorsport reliability.

• Direct Replacement – Bolts into the OEM subframe without modification.

• Ideal for Performance Builds – Great for track, drift, and high-horsepower street applications.

Specifications:

• Material: 6061-T6 Billet Aluminum

• Raise Height: 20mm

• Fitment Type: Direct OEM bushing replacement

Compatibility:

• Toyota FR-S – 2013–2016

• Toyota GR86 – 2022+

• Subaru BRZ – 2013+

What’s Included:

• (4) Solid differential bushings (front and rear positions)

• (1) Complete set of installation hardware

Notes:

• Increased NVH (Noise, Vibration, Harshness) is expected due to solid mount design.

• Professional installation is recommended—press tools required to remove OEM bushings.

• Best paired with solid subframe and transmission mounts for a fully rigid drivetrain.

Upgrade your FR-S, GR86, or BRZ with the GKTech Raised Solid Diff Bushings for improved axle alignment, sharper drivetrain response, and track-proven durability.
