IMR’s 3S1000 10.00” Twin Disc clutch for the 3000GT VR4 and Stealth RTTT (Group Buy)

IMR’s 3S1000 is a 10.00” (254mm) Twin Disc clutch unit designed for high horsepower applications that performs well on the track and can even withstand heavy street use.  This application is known to hold 13000ftlbs of torque.

This group buy will ship products on April 24th or before.

The strap-driven plate design allows for smooth engagement and minimal clutch chatter while still being able to withstand hard launching, clutch kicking, and high RPM shifting. Designed for the enthusiast who pushes the limits of performance on their high powered vehicle and wants to maintain excellent pedal feel. The 3S1000 Twin Disc is ideal for applications with large bell housings such as the Toyota 2JZ or the GM LS engines.        

The cover assembly is machined from billet aluminum and is then Type 3 hard anodized. Our billet covers have roughly 25% more tensile strength than the competition’s cast unit. By focusing our ability on machining the strongest cover possible while maintaining minimal weight, we are basically able to eliminate any flex in the cover. Our billet covers see only .003" of flex where as a cast or stamped unit can see as much as .030" of flex. By eliminating this flex in the cover, the driver is able to operate the clutch much more consistently and confidently. All the movement being applied to the diaphragm of the clutch from the throwout bearing is used solely to engage and disengage the clutch and isn't wasted by the cover flexing first. The strength of our covers also results in greater clamping force over the same amount of area vs. a cast or stamped cover. This means our twin discs are easy to drive and have superior clamping force to make sure all the power your engine is making is being utilized. 

Flywheels are made for each specific application in either aluminum or steel. Our aluminum flywheels are machined from billet 6061-T6 aluminum to meet SFI spec 1.2 for competition in NHRA, NDRA, IDRC, IHRA, SCCA and NASA. Aluminum flywheels are Type 3 hard coat anodized to ensure their durability and performance lasts. Each aluminum flywheel includes a replaceable insert. Steel flywheels are machined from 1045 billet cores and are then black oxide treated for rust prevention

Engagement is smooth, the peddle force is reduced, and it has insane holding power. Best of all worlds
