Product Details

This SPL Parts Solid Differential Mount Bushing Set fits the 2019+ BMW Z4.

Differential Mounting Bushings for the 2019-2024 BMW Z4 (G29) eliminate the stock mushy rubber bushings to hold the differential solidly to the subframe. The stock differential bushing is known to tearing under hard driving and track use. Our bushings will never break, and will keep the differential from "bouncing around" under hard launches/acceleration. This will help prevent damage the drive shaft and half shafts, reduce wheel hop, and improve power transfer to the ground. SPL Parts bushings are precision CNC machined from 6061-T6 Billet Aluminum for an accurate fit.

The kit includes the bushings on the front of the differential pumpkin as well as the bushing on the subframe where the rear of the differential attaches to. Since Toyota and BMW don't sell these bushings separately, our solid replacement bushings are a cost effective solution vs. purchasing a completely new subframe. Sold as complete kit for one car. Made in the USA.

Features

  • Improved Drivetrain Stability: Provides better support for the differential, reducing movement during acceleration and deceleration, which enhances overall stability.
  • Enhanced Power Transfer: Minimizes drivetrain flex and movement, allowing for more efficient power transfer from the engine to the wheels, improving performance.
  • Reduced Noise and Vibration: Often made from materials designed to absorb shocks and vibrations, leading to a quieter and more comfortable ride.
  • Increased Durability: High-quality materials ensure resistance to wear and environmental factors, extending the lifespan of the differential and surrounding components.
  • Better Handling Characteristics: Helps maintain proper alignment of the drivetrain, contributing to improved handling and responsiveness, especially during aggressive driving.
