PTT 7.25 Twin-Disc Clutch Kit for 7-Bolt AWD DSM
PTT PowerTrain Technology 7.25" twin disc clutch kits for 7-bolt AWD DSM are available with the standard or high torque pressure plate and with your choice of metallic or organic discs. Note, the OEM ring gear is NOT included, but is available for purchase below.
Vehicle Fitment:
7-Bolt 4G63 DSM AWD (Eclipse, Talon, Laser turbo)
• Fits 7-bolt engine in a 1G or 2G

This slave cylinder fits both 1G/2G with minor shaving of the cylinder.
Ring Gear Notes:
The flywheel does not include a ring gear. You can reuse your factory ring gear or we offer them new as well. It is helpful to put the flywheel in a freezer prior to install and/or warm the ring gear. It's a tight fit!
• OEM Mitsubishi Ring Gear for AWD DSM (MD030629)
Throwout Bearing Notes:
Keep your stock throwout bearing during install.
The factory backing plate is needed.
Spline Tool:
1G/2G DSM will use the 7/8" x 20 Clutch Alignment Tool.
Purchase Includes:
• Aluminum Flywheel
• Twin Discs
• Floater Plate

Additional Notes:

Get the maximum performance out of your Diamond Star! You've got the big turbo, huge intercooler, big injectors, a nitrous shot for good measure, and maybe even a big crank. Now get the best clutch and flywheel there is to put behind your hard earned horsepower. PTT's ultimate Mitsubishi drag clutch features race winning low MOI combined with PTT bullet-proof reliability.
In drag racing, the launch is everything. This is the clutch that will stand up to what you have to throw at it. Once you get the car launched is when the PTT MOI advantage starts to kick in. This is the low MOI clutch discs allow you to shift quicker, and the clutch allows your engine to rev faster. The result? Lower ET's, and higher trap speeds. We have had some racers report as much as 1 7/10 second reduction in ET after installing this clutch system. A half second ET reduction is very common.
This clutch features a billet aluminum clutch cover with flush mount fasteners and brutally strong .20" thick clutch discs, resulting in a clutch with a reduced overall height. (3/8" lower than our nearest competitor's clutch!) That means you have no need to grind on, (and weaken) your clutch fork. Everything clears! Specially engineered clutch hubs practically eliminate the problems caused by excessive input shaft run-out common to the diamond star cars. Specially designed diaphragm spring and internal mounting system eliminate the extremely high loads on your engine's thrust bearing. Small diameter, radius faced release bearing reduces pedal effort to round out the package.
Engineered in reliability; Race winning performance; Legendary PTT Quality; Turn-Key installation; Attention to all the 'little' details; Lifetime Guarantee against defects in material and workmanship. Put one in your car and discover how quick you can really go!
