Broken diff ears? This is how you prevent it.

The factory cast alloy rear covers on E36 diffs are a known weak point. Once you start adding load through harder driving or upgraded bushings, it’s not uncommon for the mounting ears to crack or snap completely.

KAZZ Engineering rear differential brace plates are designed to reinforce this area and eliminate one of the most common failure points in the drivetrain.

What you’re getting:

• 5mm steel brace plate
• Precision profile cut and CNC bent
• Powder coated for durability
• Supplied with high tensile mounting hardware

About the design:
✔ Reinforces factory diff mounting ears
✔ Reduces stress under load and shock
✔ Helps prevent cracking and failure
✔ Designed to suit small and medium case E36 differentials (excluding compact)

This brace supports the rear cover and distributes load more effectively, especially under high stress conditions. For anyone running or planning to run stiffer differential bushings, this is an essential preventative upgrade to avoid damaging the factory rear cover.

No more relying on weak cast alloy to hold everything together.

Installation notes:

• Professional installation recommended
• Use supplied hardware only
• Compatible with standard or KAZZ Engineering bushings
• May not suit some aftermarket bushings
