OE-Quality CV Boot Kit for Audi and Porsche

GKN Loebro 306619 is an OE-quality TPE CV joint boot kit built for exact-fit replacement on select Audi and Porsche driveline applications. It is designed for outer CV joints where a torn, slipped, or porous boot can quickly lead to joint contamination and failure.

• Thermoplastic elastomer (TPE) boot for heat resistance in modern driveline use
• Solid black boot design with one rib
• Joint end inside diameter: 3.322 in.
• Shaft end inside diameter: 1.043 in.
• Vented boot: No
• OE-style replacement for precise fit on the specified applications

Fitment and Application Details

Compatible with Audi A4 allroad front right outer CV joint applications for 2013-2016, 2021, and 2023-2024 models, as well as Audi A4 Quattro front right outer applications for the same year groups. It also fits Audi A5 Quattro front left outer on 2023 models, Audi A5 Quattro front outer on 2022 models, Audi A5 Sportback front outer on 2022 models, Porsche Cayenne front outer on 2019-2021 models with the listed equipment notes, Porsche Macan front outer on 2015-2021 models, and Audi allroad front right outer on 2013-2016 models.

This part cross-references Audi 8T0498203 for the same application. GKN Loebro 306619 is the correct style of replacement when the original driveshaft uses a TPE boot, helping maintain the intended joint protection and fit.

What This Boot Kit Helps Address

• Torn CV boots that expose the joint to dirt and moisture
• Slipped boots that no longer seal the joint properly
• Porous boots that allow grease loss and contamination
• Heat-related boot deterioration in high-torque driveline use
• Outer CV joint protection issues on Audi A4 allroad, Audi A4 Quattro, Audi A5, Audi allroad, Porsche Cayenne, and Porsche Macan applications

Installation Notes and Tips

Match the replacement boot to the original joint design before installation, especially on vehicles originally equipped with TPE boots. Confirm the joint end and shaft end dimensions, and verify the vehicle position and notes for your specific Audi or Porsche application before service. Professional installation is recommended for proper sealing and driveline protection.
