The Valair Street Dual Disc Clutch NMU70G56DDSN for your 2005.5-2017 Dodge 5.9L/6.7L Cummins 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.

Very good clutch plenty of holding power. easy to install as long as you know what your doing and have the right tools. will take some getting used to with hd hydraulics and solid flywheel. will recommend if you plan on putting a programmer on because the stock clutch isnt worth a shit. 07 5.9l w/ edge juice w/ attitude s&b cold air intake with scoop, 5in straight pipe exhaust

What is light towing is it 5k or 15k lbs Just want to know how much I can tow safely
View Staff Answer 
7,500-10,000lbs is considered light towing. Anything more than that and an oganic clutch would be recommended.
Would I be able to town up to 20-25,000lbs with this clutch
View Staff Answer 
This clutch is designed for trucks with performance modifications up to 650HP that compete in racing or see hard use. While light towing is possible, this clutch is too aggressive for heavy towing.
