Competition Clutch Triple Disc Clutch Kit for K-Series

Competition Clutch Triple Disc Clutch Kit for K-Series

The Competition Clutch triple disc 1848037-3 (Old SKU: 4T-8037-C) is the top of the K-series clutch ladder, the kit you buy when a twin disc is no longer enough. Three 184mm ceramic discs stack the friction area needed to put four-digit power through a K20 or K24 without slip, which is why these end up in big turbo DC5 RSX drag builds, K swapped EG and EK hatches, and roll race Civics far more often than in anything with a license plate frame from a dealership. This is a full race clutch, and Competition Clutch does not pretend otherwise.

What It Is and Why It Works

Multi-disc clutches solve the physics problem of small-diameter Honda gearboxes: instead of one huge disc, you multiply surface area with several compact ones, keeping rotating mass and inertia low so the engine still revs like a race motor. Here you get three 184mm ceramic friction discs with rigid hubs, a 4140 forged steel flywheel, a 6061 T6 aluminum cover, and a 6150 steel diaphragm, with the release bearing included in the kit. Per manufacturer, the package is rated in the 1000 to 1500 horsepower range depending on application, and the 184mm full race series has been proven in heads-up drag racing for years.

Everything in the assembly is serviceable. Discs and floater plates are replaceable individually, so a worn clutch is a rebuild, not a repurchase. If your power goal is under roughly 900 horsepower, we would point you at the Competition Clutch twin disc instead; it is cheaper, quieter, and easier to drive, and we carry it as well. Buy the triple when your turbo, fuel system, and chassis actually demand it.

Fitment

Every application above is manual transmission only. The Accord, CR-V, and Element rows are the 2.4L K24 manual cars and come straight from the manufacturer catalog. Because this clutch bolts to the K-series crank and works with the K-series gearbox, it is also the right part for K20 and K24 engine swaps into EG, EK, and other chassis running a K-series transmission, which is where a lot of these kits actually end up.

What to Know Before You Buy

Know what you are signing up for. Multi-disc race clutches rattle at idle in neutral; that is the floater plates moving on their stands and it is normal, not a defect. The rigid ceramic discs engage abruptly, chatter in traffic, and make gear noise a stock clutch never will. This kit belongs in a car built around it: built axles, upgraded engine mounts, a real fuel system, and a driver who accepts race car manners. If any of that gives you pause, step down to the twin disc or the Super Single and be happier.

Give it a proper break-in of several hundred easy street miles (roughly 400 to 500 per manufacturer guidance) before hard launches so the discs seat evenly. While the transmission is out, replace the slave cylinder and flush the hydraulic fluid; consistent pedal feel matters even more with three discs than with one. Our direct recommendation: for a dedicated 1000 plus horsepower K-series drag or roll race build, this kit is the honest choice at its price, and the included forged flywheel and bearing mean there are no surprise add-ons at install time.
