South Bend Stage Clutches


Southbend clutches for the '05-10 Cobalt, '04-07 Redline, and '08+ HHR SS with the F35 transmission. This is the preferred brand used by ZZP in our builds where customers let us choose the clutch. We use these in our own cars.

Just because a clutch pedal is harder to push, does not mean that the pressure plate is heavier. It just means that the pressure plate was built a different way. The ZZP Stage 4 clutch has a similar to stock pedal feel but has held over 550 ft lbs at the wheels in Matt's ‘08 LNF Cobalt SS without slipping.

Stock pressure plate is 1200#s.

Stage 2 (up to 300 ft lbs)- Discontinued - Used a stock modified pressure plate to increase clamp load. The discs metal backed Kevlar® linings provide a smooth engagement and have the torque capacity to handle high horse power, high revving engines . These clutch kits maintain a stock feel at the pedal and have unmatched durability. Front and back of metal backed TZ Kelvar® lining. The steel backing gives this lining the ability to spin up to 15,000 rpm. Will not support the extra torque of turbo applications.

Stage 3 (up to 350 ft lbs)- New Sachs upgraded pressure plate, increased clamp load above what the stock pressure plate and is rated at about 1600#s. It comes with a full face ceramic sprung disc.

Stage 4 (up to 400 ft lbs)-
New Sachs upgraded pressure plate, increased clamp load above what the stock pressure plate and is rated at about 2100#s. It comes with a full face ceramic sprung disc.

Stage 4 plus (up to 475 ft lbs)- 2200-2300# intended for 400+whp setups.

'04-07 Cobalt/Redline S/C (LSJ) we recommend a Stage 3, or a Stage 4 or 4 plus for large builds(usually turbo).

'08+ Cobalt SS T/C (LNF) we recommend a Stage 4 or 4 plus (LNF's make much more low end torque than the LSJ).


Torque Spec Flywheel to crank 39 ft lbs and 25 degrees. (OEM flywheel bolts)
Torque Spec Pressure plate to Flywheel is 22 ft lbs.
