Description
Eliminate common oil leaks and enhance engine reliability with the 034Motorsport Billet Aluminum Rear Main Seal Upgrade for Volkswagen and Audi 1.8T and 2.0T FSI engines. Designed as a direct replacement for the failure-prone stamped steel OEM rear main seal, this billet solution is built to endure the extreme conditions found in both street and performance driving.
Manufactured from high-quality 6061-T6 billet aluminum and anodized in gloss black for durability and corrosion resistance, this rear main seal housing provides a significantly stronger and more precise fit than the stock unit. It includes a premium OEM Elring Viton FPM (fluoroelastomer) seal with an integrated tension spring, ensuring a long-lasting, leak-free seal against the crankshaft.
The OEM PTFE-style seal is notorious for premature failure, leading to oil leaks, crankcase pressure issues, and even misfires. The 034Motorsport rear main seal upgrade is a proven solution designed to eliminate these problems permanently. Whether you're performing a repair or looking for preventative maintenance, this upgrade is a must-have to protect your engine and maintain peak performance.
