Spec 89-94 Nissan Skyline R32/93-98 Skyline R33 Super Twin SS Trim Clutch Kit
The RB26DETT left the factory with about 260 lb-ft, and a modern single or twin turbo conversion can triple that. When an R32 or R33 GT-R starts slipping on boost, the stock twin plate or an older upgrade is simply out of capacity. SPEC SN26SST is the Super Twin in SS-Trim for the R32 and R33 GT-R with the pull type release, rated by SPEC at 1086 ft-lb for high power builds that still see street miles.
A Super Twin stacks two friction discs between the flywheel and pressure plate, so the clamp load works on twice the surface area without growing the diameter or making the pedal unbearable. SPEC aims the line at street and track cars in the 700 to 1500 ft-lb range and promotes near stock drivability, long life and a bolt in install with no shimming. SS-Trim sits in the middle of SPEC's Super Twin range: it carries a higher torque rating than the Organic Trim version (SN26SST-O, 847 ft-lb) while staying below the E-Trim and ST-Trim race versions, which suits a GT-R that is driven to events rather than trailered. SPEC lists the assembly at 37 lb. Our twin disc vs single disc guide covers why twin discs are the usual answer on big power RB builds.
On cars this age the hydraulics and release parts fail as often as the clutch. Check the master and slave cylinders, replace old fluid, inspect the release fork and the pull type bearing retainer, and look for oil from the rear main seal on the bellhousing. Our clutch slipping guide covers a load test that separates real slip from release problems, and the manual transmission repair cost guide helps you plan the full job.
SPEC lists SN26SST for the Nissan Skyline R32 GT-R pull type (1989-1994) and the R33 GT-R pull type (1993-1998). It is a GT-R RB26DETT part, not for GTS-t RB25DET or RB20 cars, which use different clutches such as the SPEC RB25/RB20 Stage 2. It is also not for cars converted to a push type release; those use push style kits like the Clutch Masters FX850 Street twin disc. If you are not sure what release your car runs, send us the chassis code and conversion history. For a lighter build, the SPEC Stage 2 single disc for R32, R33 and R34 and the rest of our clutch kit collection are worth a look.
