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 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)
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

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.

I have put about 500 miles on this clutch so far. It is significantly quieter than other twin disk comp clutch that was in the truck.
Pedal feels a lot like stock. The clutch is very "driveable" versus some of the on/off ceramic set ups. The downside for some is that it is no good for drag racing or sled pulls.
I have it on a stock 3500 and I am very happy with it so far. Backing up with it is very smooth also. Where as with the ceramic clutches, it is very grabby ~ almost violent.
