Quiet Street Dual Disc Clutch - 550HP & 1100 Ft-lbs - The Quiet Street Dual Disc offers more holding power and a wider range of use over a single disc clutch, while retaining similar driving characteristics. With a 3800lb diaphragm style pressure plate quick shifts are still possible while pedal pressure will be just over stock.

Organic: The Organic Street Dual Disc is ideal for trucks from stock to 550HP that tow heavy on a regular basis. Clutch engagement will be very close to stock feel. (Not recommended for Racing). Quiet: This clutch has proven in testing to be the answer to the center plate noise that our customers have been asking for. The drive straps installed from the floater plate to the flywheel will eliminate rattle when the clutch pedal is pressed in. This clutch requires extra care during the installation to ensure that the drive straps are properly installed.

  • Organic Clutch Discs

G56 Gear rollover facts: When converting a G56 transmission over to a solid mass flywheel vs. dual mass flywheel, gear rollover is inevitable. Gear rollover noise is often heard when the vehicle is idling or under a load in low RPM ranges (often referred to as sounding like marbles in the transmission). This is completely normal.

Gear rollover noise is caused by reverse engine spike and can in most cases be drastically reduced by simply changing the oil in the transmission or reducing engine spike produced by inadequate engine components (ex. misfiring injector, FCA problems, Electronic programming). The oil recommended by the transmission manufacture Mercedes-Benz is Mobil Delvac Synthetic Transmission Fluid 50. Valair Inc. recommend draining completely and refilling with 7 quarts. Only 6 quarts will fit when utilizing the fill hole, the final quart will need to be filled through the shift tower.


  • Can you tell me for the torque specs for the bolts. I’m putting a different motor in my truck and lost the instructions since the clutch has been installed for almost a year
