SUMO Rear Differential Bushing Inserts – Subaru BRZ / Toyota 86

SUMO Rear Differential Bushing Inserts – Subaru BRZ / Toyota 86

The SUMO Rear Differential Bushing Insert Kit is designed to stabilize the differential by reinforcing the factory bushings. This helps maintain proper pinion angles under load, resulting in smoother gear shifts, reduced torque loss, and improved power delivery to the wheels.

Each kit includes inserts for both the differential cradle and the support outrigger, ensuring a complete upgrade for the rear differential mounting system.

Key Features:

• Application: Rear differential

• Position: Cradle + support outrigger inserts included

• Maintains correct pinion angle under load

• Reduces initial torque loss for stronger launches

• Improves power transfer to the wheels

• Enhances gear shift feel and driveline stability

Vehicle Compatibility:

• Subaru BRZ: 2013–2020

• Toyota 86: 2013–2020

• Toyota GR86: 2022–present

• Subaru BRZ (2nd Gen): 2022–present

⚙️ Note: Designed as an insert kit — works with existing OEM differential bushings to reduce compliance and improve driveline response.
