E36 / E46 (non-M) Polyurethane Front Differential Mount Bushing and M14 Bolt Upgrade Combo

Overview

Introducing Garagistic Polyurethane Differential Mounts for your BMW E36, E46, or E86 - the ultimate solution to eliminate those annoying clunks and thuds coming from your rear differential. If you've experienced loud noises while releasing the clutch from a dead stop or heard your differential trying to escape during quick shifts or hard driving, chances are your stock front differential bushings are worn out or failed. With our high-quality polyurethane mounts, you can bid farewell to these issues and enjoy a smoother driving experience.

Our M14 diff bolt is fantastic as it is stronger than OEM as it is grade 10.9 (OEM bolts are 8.8), and also has an increased shank thickness (14mm) while maintaining the OEM thread pitch of 12x1.5. This means that you do not need to drill and tap your differential threaded holes to M14, as we all know that these differentials are getting rarer and harder to find due to the increase in popularity of our chassis' for racing and drifting. 

Polyurethane vs Aluminum

We offer three different material options for our differential bushings to suit your specific needs:

• 80a (Soft Polyurethane): Ideal for those seeking an OEM+ feel and a subtle upgrade for their street car. Provides improved performance without compromising comfort. Perfect for street enthusiasts who want enhanced power transfer to the wheels.

• 95a (Hard Polyurethane): Great for dual-purpose aggressive street and track applications. Offers a noticeable performance upgrade with slightly more firmness compared to the 80a option. Still suitable for street use but provides better handling during spirited/track driving.

• Aluminum (Solid Bushing): Recommended for race applications only. Provides maximum rigidity and performance for hardcore track enthusiasts and competitive racers. Not intended for street use due to its extreme stiffness.
