OE-Quality CV Boot Kit for Audi and Volkswagen

The GKN Loebro 305756 CV joint boot kit is built for OE-style driveline repair where exact fit and material choice matter. It uses TPE construction to match modern high-torque axles and help protect the joint from contamination, heat, and grease loss.

The GKN Loebro 305756 is designed for vehicles that originally used a TPE boot, including Audi A3 front right inner and front left inner applications.

Detailed Description

GKN Automotive supplies driveline components engineered around the original joint design, and this boot kit follows that approach with a precise TPE replacement boot. TPE is commonly used on factory driveline assemblies because it handles elevated operating temperatures from modern torque loads, making it a strong choice for maintaining CV joint protection. If the original driveshaft uses a TPE boot, the matching replacement boot kit is the correct service path. Part number 305756 is also referenced for the same application under OE cross numbers 1K0407283D and 3C0498201A.

What This Part Helps Address

• Torn CV boot material
• Slipped boot that no longer seals the joint
