Street Dual Disc Clutch - 650HP & 1200 Ft-lbs 
The 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.


The Ceramic Street Dual Disc is best suited for daily driven trucks that have performance modifications up to 650HP that do see some racing or hard use. Light towing is possible; clutch engagement will be somewhat aggressive but tolerable.


  • Dual Disc Kit - up to 650HP
  • Ceramic Buttons
  • Nodular Iron Flywheel and Billet Floater plate
  • Pressure Plate Load - 3800#
  • Not for competition use

Kit includes: New Nodular Sprung hub G56 Dual Disc Flywheel, 3800# Pressure Plate, Ceramic Clutch Discs, Release Bearing, HD Pilot Bearing, Modified Clutch Fork, Bolt Kit, and Alignment Tool & HD Hydraulic Kit NMU70HYD-03

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.” We at 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.

Disengagement noise:
On all dual and triple disc clutches, a noise will be associated with the disengagement of the clutch. This is due to the intermediate plate(s) floating freely in the lugs of the flywheel. This is NOT a bad throw out bearing!!! The noise can possibly get more noticeable during the break-in period of the clutch due to the intermediate plate(s) seating in.
