Clutch Kits by Application

A clutch kit is not bought by brand or by price - it is bought by application, and the application is written in three numbers: disc diameter, input-shaft spline, and the car and years the kit was built for. This page pulls together 24 in-stock clutch kits from Ram, McLeod, Centerforce, Advanced Clutch and Tilton, from $219.00 to $1,895.00: stock-style OEM replacements, street-performance single discs, off-road kits, and twin-disc kits, for GM cars old and new, Ford Mustang across four generations, Mopar including the modern Challenger, Jeep Cherokee and Wrangler, and a pair of import applications. Every diameter, spline and material quoted below comes from that product’s own listing. Every order over $200 ships free.

OUR CLUTCH KIT PICKS

Product	Spec (from the product listing)	Price	Why it is here
GM 10.5 Clutch Kit 1-1/8 x 10 Spline	OEM single-disc kit: 10.5 in diameter, 1-1/8 in x 10 spline, sprung hub, organic disc, Ram, built for GM (per listing)	$219.00	The value pick and the floor of this page: a stock-style replacement kit in the classic GM 10.5 in / 10-spline pattern, for the car that just needs its clutch back.
Clutch Kit- Super Street Pro GM	Super Street Pro single-disc kit: 11 in diameter, 1-1/8 in x 26 spline, sprung hub, organic / ceramic disc, McLeod, built for GM V8 (per listing)	$450.00	The street-performance pick, and one of the deepest-stocked kits on this page when it was built: the same GM application in the later 26-spline pattern, with an organic/ceramic disc.
Clutch Kit - RST Street Twin Ford/GM	RST twin-disc kit: dual disc, 9.687 in diameter, 1-1/8 in x 26 spline, rigid hub, organic discs, McLeod, built for Ford / GM (per listing)	$925.00	The twin-disc entry point, and the deepest-stocked twin here: two organic discs share the load instead of one, which is the whole idea of the twin-disc shelf below.
Concept 10.5 Clutch Dodge Challenger	Concept 10.5 dual-disc kit: 10.5 in diameter, 1-1/8 in x 26 spline, sprung hub, organic discs, Ram, built for Dodge Challenger 2008-20 with the Gen III Hemi (per listing)	$1,149.00	The modern-Mopar pick: a dual-disc kit whose listing names its car and its engine family outright - Challenger, 2008-20, Gen III Hemi.
Clutch Kit RXT Street Twin GM	RXT 1200 twin-disc kit: dual disc, 9.687 in diameter, 1-1/8 in x 26 spline, rigid hub, organic discs, steel flywheel, McLeod, built for GM LS-Series / Gen V LT-Series (per listing)	$1,895.00	The ceiling of this page’s ladder: McLeod’s RXT 1200 kit for LS and LT cars, the one kit here whose listing also states a steel flywheel in the box.

THE THREE NUMBERS THAT DECIDE FITMENT

Diameter runs from 8.4 in on the Honda Civic / Acura RSX kit here to 12 in on the LS kits - it is set by the car and its flywheel, not by preference. Spline is the input shaft of YOUR transmission, written as shaft diameter x spline count, and it is where most wrong orders happen: GM alone appears on this page as 1-1/8 in x 10 spline (the early pattern, on the Ram OEM kits) and 1-1/8 in x 26 spline (the later pattern, on the McLeod, Centerforce and ACT LS kits). Same make, same disc diameter family, two different shafts - a 10-spline disc does not go on a 26-spline shaft. Ford tells the same story: the 1986-2000 Mustang kits here are mostly 1-1/16 in x 10 spline, while McLeod’s Super Street Pro Ford kit is 1-1/8 in x 26 spline - the pattern of the transmission behind the engine, which is exactly the kit a transmission-swapped car needs and a stock car does not. Mopar’s single-disc kit here is 1 in x 23 spline; the Jeep kits are 1-1/8 in x 10 spline; the Miata kit is 22 spline. Count your shaft, or read it off the transmission, before you order. Application - the car and years in the listing’s fitment line - is the final check, and every listing on this page closes with the same advice, which is worth following: check the manufacturer’s application guide for your specific vehicle. Questions before you order? Call 213-549-4279 (Mon-Fri, 9am-5pm PT) and we will read the listing with you.

SINGLE DISC OR TWIN DISC

Nineteen of the kits here are single disc - one friction disc between flywheel and pressure plate, in diameters from 8.4 to 12 in. The five twin-disc kits (McLeod’s RST and RXT lines, Ram’s Concept 10.5 for the Challenger, and Tilton’s ST-246 for LT1/LT4 cars) put two smaller discs - 9.687 to 10.5 in - in the same space, so the friction area roughly doubles without a bigger flywheel. That is the honest, mechanical reason twins exist; what this page will not do is quote a horsepower or torque number for any kit here, because none of these listings publishes one - a rating a listing does not state is a rating we do not invent. If a number decides your order, call us and we will check the maker’s data for the exact kit.

WHAT THE DISC IS MADE OF, AND THE HUB UNDER IT

The listings state each disc’s friction material, and the spread on this page is the category in miniature: organic on the OEM replacements, the Jeep kits and the twins; organic / ceramic on McLeod’s Super Street Pro and Extreme Street singles; metallic / organic on Ram’s Power Grip F-Body set; full metallic on Ram’s HD Power Grip Corvette kit; ceramic / metallic on Centerforce’s DFX; and plain ceramic on McLeod’s Street Extreme Mustang kit and the RXT twin. Hubs split the page the same way: nearly every single-disc kit here is a sprung hub (the disc’s springs absorb engagement shock), while the McLeod RST and RXT twins are listed as rigid hub - both facts are printed in each kit’s own spec line, so compare the line, not the headline.

THE APPLICATION MAP

GM, early: Ram’s 10.5 in and 11 in OEM kits in the 10-spline pattern, and Centerforce’s DFX, whose listing dates its GM applications 1962-84. GM, LS era: McLeod’s 12 in Super Street-Pro for 97-13 LS cars, Ram’s HD Power Grip for the 97-09 Corvette, Ram’s complete LS kit with a 168-tooth steel flywheel for a 6-bolt crank, and the RST / RXT / RXT 1200 twins. Ford Mustang: Ram’s OEM replacement and McLeod’s Extreme Street for the 1986-2000 5.0L cars, McLeod’s Street Extreme for 2005-10, and Centerforce’s Dual Friction for the 2011-14 GT 5.0L. Mopar: McLeod’s Super Street Pro single in the 23-spline pattern, and Ram’s Concept 10.5 twin for the 2008-20 Challenger. Jeep: Centerforce I for the 1994-99 Cherokee, Centerforce II and ACT’s HD Offroad kit for the Wrangler JK. Imports: ACT’s HD Street kits for the 1990-2005 Miata and the 2002-11 Civic / RSX - proof the same three-number rule runs the whole category, at 8.4 and 8.8 in diameters the V8 kits never see.

AN HONEST NOTE ON WHAT IS NOT ON THIS PAGE

The wider Clutch Kits range linked below also carries parts that wear a kit’s name loosely: clutch discs sold on their own, pressure plates and covers sold on their own, and UniClutch’s fitment kits and spline adapters, which adapt that system rather than replace a clutch. They are deliberately not on this page - every product here is a complete kit or set in its own listing’s spec line. One listing was excluded on exactly that test: a Centerforce Dual Friction product titled as a Mopar clutch kit whose own spec line describes a clutch disc only. Read the spec line before the title, on this page and everywhere else. The wider range also holds the small-diameter multi-disc racing clutches (Tilton and Quarter Master 5.5 and 7.25 in units) - real clutches, but a different shelf, organised by the Clutches and Components collection rather than by street application.

QUESTIONS DRIVERS ASK US

How do I know which spline I need? It is your transmission’s input shaft: diameter and spline count together, like 1-1/8 in x 26. Count the splines on the shaft (or read the transmission’s spec) and match both numbers to the kit’s spec line. If the car has had a transmission swap, the shaft - not the car’s year - decides.

Does the kit include a flywheel? Most listings here do not state one, so assume the flywheel is separate unless the spec line says otherwise. Two kits on this page do say it: Ram’s complete LS kit (steel flywheel, 168 tooth, 6-bolt crank) and Tilton’s ST-246 (chromoly flywheel), and McLeod’s RXT 1200 hero above states a steel flywheel. Everything else: read the exact listing, and plan the flywheel - new or resurfaced - as its own line item.

Sprung hub or rigid hub - does it matter? The listings state which each kit has. The sprung hub’s springs cushion the moment the disc engages; a rigid hub has no such springs. Nearly all the single-disc street kits here are sprung; the McLeod twins are rigid. Neither word is a quality grade - it is a design fact printed in the spec line, and worth knowing before the kit is in the car.

Why is there no horsepower rating on this page? Because none of these 24 listings publishes one. Clutch makers do rate their kits, but the rating lives in the maker’s own data for the exact part number - call us at 213-549-4279 with the kit you are considering and we will check it, rather than printing a number we cannot source.

Can I fit it myself? Every listing here closes with the same line: professional installation is recommended. A clutch swap means the transmission comes out, the flywheel face is judged, and the release system is set up - the listings’ advice is the advice.
