Competition Clutch Stage 1 Gravity Clutch for K20A3/A4

Competition Clutch Stage 1 Gravity Series 2400 – RSX Base / EP3 Civic Si / Accord 5spd

The Competition Clutch Stage 1 Gravity Series 2400 is for mild K-series street cars where the stock clutch starts to tap out. Not because you built a drag car, but because you actually drive it hard, added bolt-ons, and put heat in it. Expect roughly a 40–50% bump in torque capacity with a pedal that’s very close to stock, so you can still slog through traffic and commute without hating life.

This Competition Clutch 2400 Acura RSX / Civic / Accord setup fits the K20A3 and similar K-series in:

• 2002–2005 Honda Civic Si (if you’re trying to buy Stage 1 Clutch Honda Civic or a Honda Civic Si Stage 1 Clutch, this is the one)
• 2002–2006 Acura RSX Base 5spd (perfect if you need an Acura RSX Base 5spd clutch or a Stage 1 Clutch Acura RSX)
• 2003–2006 Honda Accord 5spd (solid choice if you’re looking to buy clutch for Accord 5spd or a Stage 1 Clutch Honda Accord)

Trade-offs matter, so here’s the blunt part. This clutch is not for forced induction. No turbos, no superchargers, no nitrous. Boost and spray hit the drivetrain with sharp torque spikes and extra heat that an organic Stage 1 clutch won’t be happy with over time. If you’re planning boost “eventually,” just skip this now and move up a stage instead of buying twice.

Where the Gravity Clutch K20A3 / K20A4 setup really works is naturally aspirated K-series builds. A K20A3 or K24A4 with intake, header, exhaust, and a decent tune sits right in its sweet spot. It handles the extra torque and temperature without slipping, but it won’t hammer you with a heavy pedal, nasty chatter, or an on/off engagement.

That balance is the whole story. You get a clutch that hangs on when you lean into it, stays predictable in traffic, and doesn’t chew up the gearbox or your left leg. We still run Competition Clutch Stage 1 setups on our own mild K builds for exactly that reason, they just work without making the car feel like a chore to drive.

Stick to the recommended 300-mile easy break-in if you want it to last. Let the disc bed in properly, then beat on it. If you launch it hard right out of the shop, you’re just throwing away lifespan for nothing.

Fitment note (read this before you hit “buy”):
The SKU: COC-8036-2400 Gravity Clutch is only meant to run on the OEM flywheel. If you’ve got a 2-800-ST flywheel, you’ll need an 8037-xxxx series Competition Clutch instead. So if you’re about to Purchase Competition Clutch K20A3 or a Gravity Clutch K20A3 buy / Gravity Clutch K20A4 purchase, double-check which flywheel is on the car before you order.
