PRE-ORDER: Available in October
When a belt lets go on your 3.0T, the stock front main seal usually goes with it. That thin stamped-steel wiper seal can shred and ingest belt fragments, and once it does, you're looking at an oil leak, a mess in the engine bay, and possibly a misfire that catches you off guard.
The Vorsprung Autowerk Billet Aluminum Front Main Seal replaces that weak point with a CNC-machined 6061-T6 aluminum holder finished in gloss black anodizing, paired with an OEM Viton Elring seal and integral tension spring. It holds up to higher crankcase pressures than the factory seal, so you get a tighter, more dependable seal around your crank pulley even when your engine is working hard. Grade 12.8 hardware is included, so the whole kit is ready to install.
Built for B8/B8.5/C7 Audi A4, A5, A6, A7, Q5, SQ5, S4, and S5 owners running the EA837 3.0T supercharged engine, this is the same proven design already trusted across the Audi tuning community.

Install it once during your next belt service, and stop worrying about what a bad belt might take with it. Give your 3.0T a seal built to outlast the belt.
Front Main Seal FAQ
Do I need to replace anything else while I'm in there?
Since you're already removing the crank pulley and belt to access this area, it's a good time to inspect or replace your supercharger belt and check your tensioner pulley for play.
What's included in the kit?
The CNC-machined 6061-T6 aluminum seal holder (gloss black anodized), an OEM Viton Elring seal, integral tension spring, and Grade 12.8 mounting hardware.
Does this fit the EA839 2.9T/3.0T twin-turbo engine?
No. This seal is designed specifically for the EA837 3.0 TFSI supercharged engine and does not fit the EA839 twin-turbo engine.
Can I install this myself?
Yes, if you're comfortable removing the crank pulley and accessory belt. No special tools beyond standard hand tools are required.
