ECS RA4 Clutch & Flywheel Systems Sale | Audi B6 A4

Give your Audi the clutch it deserves this Holiday season. We've assembled three very special clutch packages built around the ECS Tuning RA4 lightweight flywheel.

Mate our new, low mass flywheel to a bigger 240mm clutch. Choose S4, RS4, or Clutch Masters RS4 clutch kits for a smooth, powerful clutch/flywheel package that revs faster but won't forget its manners in traffic.

No modifications required. Bolt them on and go complete kits that include everything you need, right down to fresh bolts and a clutch alignment tool.
