E36 SOLID DELRIN DIFFERENTIAL BUSHING KIT

Description

Now available, the Garagistic E36 Delrin complete differential mounting kit! This kit contains all 3 of the bushings that you will need to replace the OEM soft rubber units. Have you ever heard a loud thud in the back of your car? Especially when starting into gear from a dead stop? It sounds like something is trying to escape your trunk! This is usually a sign of tired or worn-out differential bushings that are allowing your diff to thump against the rear subframe. Replace and upgrade from the factory rubber bushings to these Delrin mounts. These bushings will keep your differential under control, allowing better power delivery and reducing slop in the rear end. A must-have for any car making more than factory power, and a great upgrade even for a stock car. Keep that diff under control with Garagistic E36 differential mount bushings!

Garagistic 14mm Bolt Upgrade

If you plan on doing any serious driving, make sure to click the dropdown and select our Garagistic M14 Bolt Upgrade - a tried and tested solution to weak stock diff bolts! With a 14mm shank and threads that match the factory thread pitch of the holes on your differential, M12x1.5, our diff bolts are a fantastic upgrade that improves on both overall strength and fitment, while also not requiring you to drill and tap your differential to M14.

Upgraded M14 Bolt Specifications

• Shank Thickness: 14mm
• Thread Pitch: M12x1.5 (Same as the OEM threaded hole on the differential)
• Coating: Clear Zinc-Coated (for rust prevention)

*Note: This upgrade comes with a bushing pre-drilled to 14mm for ease of installation.

M14 Bolt Torque Spec

• Torque: 110 Nm (81 ft lb) with blue Loctite (242 or 243) on clean, dry threads. Do NOT exceed this.
• Why: The bolt threads into the factory M12x1.5 hole in your differential. Going past spec stretches the bolt and risks pulling the factory threads out of the housing, no matter how strong the bolt is.
• Install: Recheck torque after the first heat cycle or track day. If you run 80A bushings on a drift car, pair this bolt with a diff brace.

Differences Between Poly and Delrin/Solid Bushings In This Application

We offer the Garagistic E36 differential bushing kit in 3 different materials: 80A poly, 95A poly, and solid Delrin. Each material has its intended application and benefits. The 80A poly is the happy medium between upgraded bushings and plush OEM rubber. It is intended for the spirited street driver, and occasional Auto-X and track use. It offers a definite increase in performance with a limited increase in noise transfer and harshness. The 95A is the next tier up on the poly scale, offering a stiffer material than 80A and increased performance to match. If you have a car with a louder exhaust and or a car intended for only weekend use in the canyons or on Auto-X and track circuit this is the bushing for you. Finally, the solid Delrin bushings are for the ultimate in performance. It is designed for the truly hardcore racers and track enthusiasts.
