McLeod Tuner Adventure Series 12-18 Jeep Wrangler 3.6L Super Trail Pro Clutch Kit
McLeod 776004 is the Adventure Series Super Trail Pro clutch kit for the 2012-2018 Jeep Wrangler JK with the 3.6L Pentastar V6 and the six-speed manual. It is aimed at the JK that has outgrown a stock-style clutch: 37 inch or larger tires, heavy armor, a supercharger or turbo kit, or a stroker build. If your Wrangler slips in the upper gears on the highway, smells hot after a climb, or a stock replacement clutch did not last, this is the heavier-duty step McLeod makes for that Jeep.
The clutch sits between the flywheel and the input shaft of the JK's NSG370 gearbox. Every time you launch on a grade, crawl in low range or tow, it has to hold engine torque multiplied by tire size and axle gearing. McLeod builds the Super Trail Pro with a high clamp load pressure plate and a dual-performance disc that uses organic friction on one side and ceramic on the other. The organic side keeps engagement smooth enough for a daily driver, while the ceramic side adds holding power and heat tolerance. McLeod recommends it for serious truck and off-road use with engine mods, added vehicle weight and tires from 37 in up.
If your Jeep is closer to stock, with mild mods and moderately larger tires, McLeod's lighter-duty option is the Trail Pro 775004, which uses a steel-backed full organic disc for softer engagement.
Rule out the release side first. McLeod's own tech tip on 2007-2018 JK bearing noise says the factory mechanical release system uses a plastic pivot ball, a thin release bearing collar, a fork pivot and an external slave, and wear in any of them changes the release ratio and causes rattle and poor release. A soft or leaking slave can mimic a failing clutch. To test for true slip, pull from low rpm in sixth at firm throttle and watch whether rpm climbs ahead of road speed; our slipping diagnosis guide walks through it. Gearbox noise and shifting complaints are covered in the Wrangler JK and JL transmission service guide.
McLeod lists 776004 for the 2012-2018 Wrangler JK with the 3.6L engine and manual transmission, two-door and four-door Unlimited, all trims. It does not fit the 2007-2011 JK with the 3.8L, which uses McLeod 776002, or the 2018-and-later JL. Because 2018 was a split year with both JK and JL on sale, confirm your body style. This part number is the clutch kit only; McLeod sells a separate pack with a flywheel under 776004K. If your Jeep has a swapped engine or gearbox, send us the year and VIN before ordering. Other JK clutch options are in our rebuild kits collection, and the JK clutch replacement cost guide lays out the labor.

No. The 776004 is for the 2012-2018 JK with the 3.6L V6. The 2007-2011 JK has the 3.8L engine and takes McLeod's 776002 Super Trail Pro kit instead. It also does not fit the 2018-and-later JL.
Trail Pro uses a steel-backed organic disc for mild mods and larger tires. Super Trail Pro adds a dual organic and ceramic disc with a high clamp load pressure plate, aimed at 37 in and larger tires, heavy rigs and forced induction or stroker engines.
No. 776004 is the clutch kit with pressure plate, disc, release bearing, pilot bushing and alignment tool. McLeod sells a pack with a flywheel under part number 776004K. Have your existing flywheel resurfaced or replaced during the install.
Often it is the release system. McLeod's JK tech tip blames worn plastic pivot balls, grooved release bearing collars, fork pivots and weak slave springs. Its 1250 hydraulic release bearing replaces those parts and is worth doing at the same time as the clutch.
Expect most of a day. The transmission has to come out, and the transfer case and driveshafts come with it or are separated. A shop typically quotes around six hours, longer if the release system is also upgraded.
