What exactly is included in this kit?

This kit includes all the necessary solid bushings to replace the stock rubber mounts for the differential. You'll get the bushings for the front of the differential pumpkin and the bushing where the rear of the differential attaches to the subframe.

Why would I want solid differential bushings instead of rubber ones?

Stock rubber bushings can tear under hard driving, leading to differential movement. Solid bushings keep the differential held firmly in place, which helps prevent damage, reduces wheel hop, and improves how efficiently power gets to the wheels.

Is this a difficult installation?

Installation involves replacing the differential bushings. Refer to the manufacturer's installation instructions for detailed steps and any specific tool requirements.

About this part

Product Details

When you're pushing your 2019-2024 BMW Z4 hard, especially during launches or track use, the stock rubber differential bushings can tear and flex. This SPL Parts kit gives you solid aluminum bushings to replace those weak points. You get the front differential pumpkin bushings and the rear subframe bushing, all in one complete kit made right here in the USA.

These aren't just replacements; they're an upgrade. By holding the differential firmly in place, these CNC-machined 6061-T6 billet aluminum bushings prevent excessive movement. This means less chance of damage to your driveshaft and half-shafts, a noticeable reduction in wheel hop, and more of your engine's power making it to the wheels. It's a cost-effective way to get a solid differential setup without needing to buy a whole new subframe.
