MMX Performance G8X M2 / M3 / M4 Rear Differential Output Shaft Heat Shield Set

Upgrading to an aftermarket exhaust system or increasing engine performance generates significantly more heat in the drivetrain area. With the exhaust sitting closer to the CV boots, this excess heat leads to premature cracking and failure of the factory rubber boots. Over time, this can cause grease leaks, CV joint wear, and eventual driveline issues—especially under aggressive track conditions.

BMW’s response to this well-known issue is to fit CS/CSL driveshafts, which come at an eye-watering cost of over £2,000. MMX offers a smarter, cost-effective alternative that achieves the same level of protection without the need for expensive drivetrain replacements.

MMX heat shields are engineered to provide a strong, effective barrier between your CV boots and the intense heat radiating from your exhaust system. Whether you’re running a factory or aftermarket setup, these shields act as a protective layer to deflect heat away, ensuring your drivetrain components last longer under demanding conditions.

Precision-crafted from T6-6062 aluminum, our heat shields are both lightweight and durable. Our signature MMX polished and anodized gloss black finish not only enhances thermal dissipation but also provides a sleek, factory-like appearance.

With everything you need in one package, protecting your CV boots from excessive heat has never been easier.
