McLeod RXT Clutch 12-15 Camaro ZL1 Aluminum Flywheel 8 Bolt
The 2012-2015 Camaro ZL1 left the factory with a supercharged 6.2L LSA, and once the pulley, tune and intake are done, the stock clutch is usually the first part to give up. Owners searching for a fix are typically chasing slip in the upper gears, a clutch that smells hot after a track day, or a pedal that no longer releases cleanly. McLeod 6306807M is the RXT twin disc clutch on a 168-tooth billet aluminum flywheel for the LSA's 8-bolt crank and a 1-1/8 x 26 spline input shaft.
The ZL1 manual pairs the LSA with a six-speed Tremec TR-6060. The RXT replaces the factory clutch and flywheel with a modular assembly: a strap-drive pressure plate, two ceramic-faced discs on a sprung hub, a floater plate between them, and a dedicated aluminum flywheel. Splitting the work across two discs gives the clutch its holding capacity without a heavy pedal. McLeod's older copy rated the RXT at 1,000 horsepower and current copy states up to 1,100, so it suits pulley, cam and E85 builds on the LSA. The lighter aluminum flywheel lets the engine rev and fall quickly between shifts, which helps on track but takes a little more throttle when pulling away in traffic.
Start with the hydraulics: check the fluid level and color, bleed the system, and confirm the pedal returns fully, because a leaking slave can fake a worn clutch. Then load the car in a high gear at low RPM and squeeze into boost. If engine speed climbs ahead of vehicle speed, the disc is slipping; a datalog showing RPM rising with flat vehicle speed confirms it. The slipping diagnosis guide walks through separating clutch slip from other faults, and our rebuild vs replace guide helps if the TR-6060 itself has synchro or bearing damage while it is out.
This listing is for the 2012-2015 Chevrolet Camaro ZL1 with the LSA engine and six-speed manual. It is not for the 2010-2015 Camaro SS, whose LS3 uses a different 6-bolt crank flange, and it is not for automatic cars. McLeod's catalog line for this part number also lists 2009-2015 Cadillac CTS-V LSA, LT1 Camaros from 2016 and later ZL1s, but this listing is sold for the 2012-2015 ZL1. If your car has had a crank, flywheel or transmission swap, count the input shaft splines and confirm the 8-bolt flange, or send us your year and VIN. Browse other options for this engine, including the organic McLeod RST 6306807 for street-only cars and the RXT HD 6306807HD for builds beyond the RXT's rating.
The pressure plate, floater and discs are marked as a balanced set, so keep them in that orientation and follow McLeod's washer order. No thread locker on the pressure plate studs or nuts; tighten them in a star pattern to 25 ft-lb and then 35 ft-lb. Use the supplied pilot tool to align the discs and check the pilot bearing, replacing it if it is worn; the Lisle pilot bushing remover makes that job easy. McLeod recommends replacing the slave cylinder at the same time, since the labor is already done. Bleed with fresh brake fluid of the grade on your reservoir cap. Break in with about 1,200 normal street engagements before any hard launches, and do not break it in on a chassis dyno. Street cars that want the factory-style flywheel mass can step to the steel flywheel RXT HD 6406807HD instead.

No. This kit is for the LSA engine's 8-bolt crank. The fifth-generation Camaro SS manual uses the LS3 with a 6-bolt crank flange, which needs a different McLeod part number.
A strap-drive pressure plate, two ceramic friction discs, a floater plate, a 168-tooth 8-bolt aluminum flywheel and a pilot tool. A release bearing is not included, so budget for a new slave cylinder.
McLeod has rated the RXT at 1,000 horsepower in older copy and up to 1,100 horsepower in current copy. For more than that, the RXT HD adds a higher clamp load pressure plate.
McLeod describes the RXT pedal as lighter than stock. The two discs provide the holding power, so the diaphragm spring does not need to be stiffer.
No. McLeod says to break the clutch in with about 1,200 normal street engagements, not on a chassis dyno, and to avoid launches until that is complete.
