Clutch Masters 89-98 Nissan Skyline 2.5L RB25DET/2.6L RB26DETT 850 PRO Series Twin Disc w/Steel FW
An RB26DETT or RB25DET Skyline with bigger turbos, a tune and E85 will overwhelm a single-disc clutch long before the engine runs out of breath. Clutch Masters 06045PTD80S is the FX850 PRO Series twin disc for the 1989-1998 Skyline with either engine, supplied with a steel flywheel, release bearing and alignment tool. If your R32 or R33 slips in third and fourth on boost, smells of hot friction after a hard run, or you are building past what the factory clutch was ever meant to hold, this is the kit built for that job.
The FX850 PRO is an 8.5 inch (216 mm) clutch that gets its holding power from two friction discs instead of a large single disc. This part number is the Sprung Race stage (PTD80): one sprung ceramic disc connected directly to a second ceramic disc, so both discs carry the load while the sprung center softens driveline shock on launches and gear changes. The PRO Series is the Clutch Masters redesign of the original FX850. It replaces the old six-post aluminum stand layout with twelve heat-treated 4140 steel stands on a 12-point nut and stud mount, and it uses a single driven hub that keeps even contact with the gearbox input shaft to cut spline wear. Clutch Masters gives an estimated torque capacity of 800 ft-lb for this kit, and every PRO unit is serviceable with rebuild parts.
Do a slip test: in fourth gear at low rpm, go to full throttle and watch for the tach to climb faster than the speedometer. Then rule out the hydraulics, because a weeping slave or master cylinder or air in the line can keep the clutch from fully releasing or fully clamping. Also be honest about use. A ceramic Race-stage twin disc bites hard and is aimed at serious power and track work. If the car is mostly street driven at moderate power, the FX850 Street twin disc for the same cars or the smaller FX725 PRO twin disc may be the better match.

Clutch Masters lists 06045PTD80S for the 1989-1998 Nissan Skyline with the 2.5L RB25DET and the 2.6L RB26DETT, both push-style release. That covers the R32 and R33 GT-R with the RB26DETT and RB25DET cars from 1993 on. It is not listed for the RB20DET R32 GTS-t, and a 1998 car may be an R34, so if yours is a late build, has a swapped gearbox or uses a pull-style conversion, send us the chassis code, engine and gearbox before ordering. These are right-hand-drive import cars, so fitment by model year alone is not enough. Browse other drivetrain parts in our rebuild kits department.

The 8.5 inch sprung twin disc clutch pack, a steel flywheel, a release bearing and an alignment tool, per Clutch Masters.
Clutch Masters gives an estimated torque capacity of 800 ft-lb for this kit.
It can be driven on the street, but it is a ceramic Race-stage twin disc with a firmer pedal and quicker engagement than stock. Street-focused cars are often happier with the FX850 Street version.
Yes. Clutch Masters says every FX850 PRO unit is serviceable, with rebuild kits and replacement components available.
Twin disc clutches have a floating intermediate plate that can make a light rattle with the pedal pressed or at idle. That is normal for the design.
