Action Clutch Stage 3 Clutch Kit for 90-93 Integra

Action Clutch Stage 3 Clutch Kit - 1990-1993 Acura Integra

When a Kevlar Stage 2 isn't enough, the Action Clutch Stage 3 (1MS) kit is the next step for your 1990-1993 Integra (DA). It's built to take abuse: a heavy-duty single-diaphragm pressure plate, reinforced drive straps, and a sprung MIBA ceramic disc, available in 4-puck or 6-puck. Rated for 170% more holding capacity than the factory clutch, it's the one you run when you're putting down real power and need the grip to match, with little compromise on reliability.

Pick The Right Year Range

Read this before you order: the 1990-1991 Integra uses a different clutch than the 1992-1993 model years, so select the year range that matches your chassis. The good news on the later cars is that the 1992-1993 kit fits both the B17 (GS-R) and B18 engines, so you're covered either way as long as you pick the correct year range. If you're unsure which you have, confirm before ordering.

Sprung MIBA Ceramic Disc

The heart of this kit is a sprung MIBA ceramic puck disc. Ceramic grabs harder and engages quicker than an organic or Kevlar disc, which is what gives the Stage 3 its holding capacity, and the sprung hub still soaks up some driveline shock to keep it livable. Be honest with yourself about the trade: a puck-style ceramic disc engages more abruptly and will introduce some clutch chatter, especially at low speed. That chatter minimizes after a proper break-in, but this is a more aggressive clutch than the Stage 1 or Stage 2 and it drives like one.

4-Puck Or 6-Puck

You can run this disc as a 4-puck or a 6-puck. The 4-puck is a bit more forgiving on engagement and the easier of the two to modulate, while the 6-puck adds more surface for holding capacity and a slightly firmer grab. Pick based on how aggressive your setup is and how much low-speed smoothness you're willing to give up, since both are a step up in bite from the Kevlar discs.

Know The Intended Use

This kit is rated for heavy-duty street use and occasional drag, road, or drift racing, the step up from the Stage 2's street-and-road-course rating. It can take the shock-loading those uses put on a clutch, so if you're launching hard at the strip or doing the occasional drift or track event on top of daily driving, the Stage 3 is built for it.

Action Clutch's Enclosed Spring Retainer

One engineering detail worth knowing: Action Clutch uses patented fully enclosed spring retainers on the disc. On conventional discs, the torsional springs inside the hub can dislodge under stress and fly into your transmission or engine internals. Action Clutch's enclosed design prevents that failure mode entirely. Their engineering team carries over 60 years of combined experience, and every kit is inspected and certified before it ships.

Fitment

Fits the 1990-1993 Acura Integra. Select your year range at checkout, 1990-1991 or 1992-1993, since the two use different clutches. The 1992-1993 kit covers both B17 and B18 engines. If you're unsure about compatibility with a swap or a non-stock transmission, contact us first.

Break-In

A proper break-in matters even more on a ceramic disc. Easy driving for the first several hundred miles lets the friction surfaces seat and heat cycle evenly, which is what settles the engagement and reduces the initial chatter. Avoid riding the clutch, and don't lean on it hard until it's broken in, since repeated slipping works against building its holding capacity.

Best For

• 1990-1993 Integra making real power beyond bolt-ons
• Drivers who want maximum holding capacity and will accept a grabbier, chattier clutch
• Heavy-duty street use plus occasional drag, road, or drift events

Not Ideal For

• Daily drivers who want OEM-smooth, chatter-free engagement, look at the Stage 1 or Stage 2
• Anyone not prepared for the more aggressive pedal and low-speed feel of a ceramic puck disc

If your Integra has the power to need it, the Stage 3 is the one that holds on: 170% more capacity, a MIBA ceramic disc in your choice of 4 or 6 puck, and the durability for occasional strip and track duty. Just pick the right year range for your chassis, go in knowing it's an aggressive clutch, and break it in right.
