What it is
This is a replacement single-mass flywheel clutch kit for TDI, built around a balanced 21 lb flywheel and a Sachs "Silent Design" clutch. It's built to run quiet at idle, no rattle in neutral, and it's rated to hold 275 ft-lbs of torque at the flywheel.
Who this is for
This is the value pick for a stock TDI on the stock turbo. If your car already has upgraded injectors and an ECU tune, or you're planning to add a turbo, cam, or exhaust upgrade later, KermaTDI recommends stepping up to the South Bend Silent Design clutch instead, it holds meaningfully more torque.
A key distinction on torque ratings
This clutch's 275 ft-lb rating is measured at the flywheel. South Bend Silent Design clutches are rated at the wheels, the number you'd see on a dyno. That means this Sachs kit can slip with even a basic chip-and-injector upgrade on the stock turbo, it's not built for a tuned car the way the South Bend option is.
Kit includes
Fitment
Mk3, Mk4, B4, A4, and A5 TDI, all with 5-speed manual transmission.
Common questions
Will this hold up to a tune? Not reliably. Its torque rating is measured at the flywheel, not the wheels, and it can slip with even a basic chip-and-injector combo on the stock turbo. For a tuned car, or one headed toward a turbo, cam, or exhaust upgrade, the South Bend Silent Design clutch is the better fit.
Is this clutch actually quiet? Yes, that's the point of the Sachs "Silent Design," it runs quiet at idle with no rattle in neutral, unlike older high-torque TDI clutches.
Does this include the flywheel, or just the clutch disc and pressure plate? The full kit, 21 lb single-mass flywheel, pressure plate, disc, throw-out bearing, and mounting hardware are all included.
