XClutch 02-04 Lexus IS300 Base 3.0L Stage 2 Cushioned Ceramic Clutch Kit
The XClutch XKTY24007-1C is a Stage 2 clutch kit for the manual 2002-2004 Lexus IS300 with the 3.0L 2JZ-GE. It suits owners whose factory-style clutch slips under boost or after power upgrades, and who want a ceramic disc that still behaves on the street. XClutch rates it at 420 ft-lb of torque capacity, including its safety factor, so there is real headroom over a stock clutch. It ships the same business day from the USA.
The pressure plate bolts to the flywheel and squeezes the disc so the 2JZ-GE can drive the gearbox input shaft. XClutch says this kit raises clamping force by 100 percent over stock, which is what stops slip once a turbo or other upgrades push torque past the factory clutch.
What sets the -1C apart is the cushioned disc. A plain ceramic button disc grabs hard, which makes stop-and-go driving tiring. This one keeps a sprung hub and adds a dampening layer between the friction faces, so the clutch takes up more gradually and the pedal is easier to modulate. XClutch recommends it for performance street use where high heat capacity is needed. If you need the most bite and do not mind a sharper engagement, the uncushioned sprung ceramic version is the -1B. For a near-stock car, the Exedy OE replacement kit keeps factory feel.
Do a slip test in fourth gear from low rpm at full throttle and compare the tach with road speed; if engine speed jumps ahead, the clutch is slipping. Our slipping diagnosis guide covers the test. Before pulling the gearbox, check the master and slave cylinders for leaks and bleed the system, because a release that drags or does not return fully can feel like a worn clutch. XClutch also says worn forks, pivot balls and hydraulics play a big part in clutch feel, so inspect them during the job.
XClutch lists XKTY24007-1C for the 2002, 2003 and 2004 Lexus IS300 Base with the 3.0L 2JZ-GE. The same kit is also catalogued for non-turbo 2JZ-GE Toyota Supra and Lexus SC300 manual cars. Key specs from XClutch:
The 2005 IS300 is not on XClutch's list for this kit. Some IS300s have been converted between transmissions, so if yours is a swap or you are unsure, send us the year and VIN and we will check before it ships. You can compare other IS300 options, such as the ACT TS5-XTSS and TS5-HDSS, before you decide.
