Detailed Product Overview

This GKN Loebro 305951 CV joint boot kit is engineered for vehicles that use a TPE boot from the factory. GKN Automotive notes that matching the original boot material and fit is important because modern drivetrains generate high torque and heat at the joint. For that reason, this boot kit is intended for exact replacement on applications such as Volkswagen e-Golf and Audi A3 Sportback e-tron front outer CV joints, as well as select Audi A3 models.

This part cross-references 1K0498203C and 81A 498 203 for the same application.

Installation Notes and Tips

• Confirm the original boot is TPE before ordering a replacement.
