Description
The MMX Performance Rear Differential Output Shaft Heat Shield Set is engineered to solve a well-known heat-related issue on BMW G8X M vehicles. Increased exhaust temperatures from aftermarket exhaust systems or higher engine output place excessive radiant heat directly next to the rear CV boots, accelerating rubber degradation and leading to cracking, grease leaks, and premature driveline wear.
Under aggressive street or track use, this heat exposure can result in costly CV joint damage and reduced drivetrain reliability. MMX Performance delivers a purpose-built, cost-effective solution that protects critical components without resorting to expensive drivetrain replacements.
Effective Heat Protection Without Costly Upgrades
BMW’s factory solution to this issue is the installation of CS or CSL driveshafts, which come at a significantly higher cost. The MMX Performance heat shield set achieves comparable protection by creating a thermal barrier between the exhaust system and the rear differential output shaft CV boots.
By deflecting radiant heat away from sensitive rubber components, these shields help maintain proper lubrication, prevent grease leaks, and extend CV boot service life, even under demanding track conditions.
Precision Construction and OEM-Inspired Finish
Each MMX Performance heat shield is precision-crafted from lightweight and durable T6-6062 aluminum, offering excellent thermal resistance without unnecessary mass. The polished and anodized gloss black finish improves heat dissipation while delivering a clean, factory-like appearance that integrates seamlessly into the G8X chassis.
Simple Installation and Complete Kit
The MMX Performance Rear Differential Output Shaft Heat Shield Set installs quickly and easily using included hardware. No permanent modifications are required, and the installation is fully reversible, allowing the vehicle to be returned to stock configuration at any time.
