MMX Rear Diff Output Shaft CV Boot Heat Shields (Pair) for BMW M3 G80 G81, M4 G82 G83, M2 G87

Rear axle CV boot protection for BMW G80 G81 G82 G83 G87

Track use and hot exhaust systems can cook the rubber gaiters on the rear output shafts of the latest BMW M cars. This pair of MMX thermal guards adds a robust heat barrier for the diff-side joints, helping keep grease in, temperatures down and driveline components protected during hard use.

Perfect for owners who push their S58-powered M2, M3 and M4 on fast road, track days, time attack or drift sessions. We have installed these on our own builds and customer cars with excellent results and strong feedback on reliability and peace of mind.

Why upgrade

• Helps prevent split CV gaiters and grease sling caused by exhaust heat
• Shields the diff output joints from radiant heat soak during extended sessions
• Improves durability of the rear half-shafts under extreme driving
• Cost-effective protection compared with replacing output shafts and boots
• Smart heat management solution for tuned S58 platforms running performance exhausts

Compatibility

Designed for the G-series BMW M platform:

• BMW M3 G80 Saloon and G81 Touring
• BMW M4 G82 Coupe and G83 Convertible
• BMW M2 G87
• Including Competition variants

What BMW says about heat at the rear output shafts

BMW has noted that extreme circuit use on G80, G81, G82, G83 and G87 models can lead to very high temperatures at the rear final-drive output gaiters. For cars used in this way, BMW references more temperature-resistant output shafts fitted to special models as an alternative. These MMX shields address the same heat exposure by deflecting radiant energy away from the gaiters to support long-term reliability.

Built for enthusiasts

• Pair of rear output shaft thermal shields for left and right sides
• Radiant heat deflector design to protect CV joint boots on the diff side
• Ideal for track days, fast road, sprint, hill climb and Nürburgring trips
