ACT 1990 Eagle Talon HD/Perf Street Sprung Clutch Kit
The ACT MB1-HDSS is the mildest step up from a factory clutch for the 1990 Eagle Talon and the rest of the first-generation DSM family. If your Talon TSi, Eclipse GSX or Laser RS has started to slip when boost comes in, chatters leaving a light, or smells hot after a spirited drive, and the car is stock or lightly modified, this kit restores the clutch with more clamp than original while keeping a soft street disc and an easy pedal.
The kit replaces the friction parts between the 2.0L and the five-speed transaxle. ACT's MB010 Heavy Duty pressure plate uses its own diaphragm design to raise clamp load and reduce deflection, and every diaphragm is heat-treated in four stages so clamp does not fade as the spring heats up. It is matched to the 3000303 Performance Street sprung disc: a full-face organic lining with high copper content for heat transfer and a steel backing for burst strength, mounted on a sprung hub that damps driveline shock before it reaches the transaxle.
ACT rates the kit at 320 ft-lb at the crank, 27 percent over the factory clutch, on a 224 mm (8.8 in) disc with a 0.875 in input spline. That makes it the right size for a healthy stock turbo car or one with a boost controller and basic bolt-ons. Owners planning bigger turbos usually step to the Xtreme-plate kits instead. ACT describes the HD kit's feel as light to moderate pedal effort, smooth engagement and OE to mild gear rattle, so it drives like a fresh factory clutch with more bite.
First rule out the release side. DSMs are known for worn clutch forks and pivot balls, which leave the pedal feeling wrong and can stop the clutch from fully releasing; our fork and pivot ball guide covers what to look for. Bleed the hydraulics and make sure the pedal returns fully so the plate clamps all the way. Then do a low-rpm, full-throttle pull in third and watch whether the tach runs ahead of road speed. Our slipping diagnosis guide walks through that test, and flare versus slip helps tell a real slip from a misfire or boost cut.
Our listing is titled for the 1990 Eagle Talon, and ACT's own application list confirms the 1990 Talon Base and TSi 2.0L. The same MB1-HDSS number is listed by ACT for the 1990-1998 Talon 2.0L turbo, the 1990-1999 Mitsubishi Eclipse 2.0L turbo (4G63T), the 1990-1994 Plymouth Laser 2.0L turbo, the 1991-1992 Galant VR-4, and several 2.4L and non-turbo 3.0L V6 front-drive cars, including the 3000GT and Dodge Stealth. The clutch is shared, but early and late DSMs use different flywheels and crank bolt patterns, and decades of engine swaps mean the parts on your car may not match the title on its registration. Check what is bolted to your crank, and send us your year, VIN and engine if unsure. All of our DSM clutch options are in the rebuild kits collection.
If the car makes more power than this kit is rated for, the MB1-XTSS Xtreme street kit holds 415 ft-lb with the same disc. The MB1-HDSS is new, in stock, ships the same business day from the USA and carries a 1-year warranty.

ACT lists the same kit for the 1990-1999 Eclipse 2.0L turbo, the 1990-1994 Laser 2.0L turbo and the 1990-1998 Talon 2.0L turbo, front or all-wheel drive. Early and late cars use different flywheels, so check what is on your crank and send us the year and VIN if unsure.
ACT rates it at 320 ft-lb at the crank, 27 percent over the factory clutch. That suits a stock or lightly modified turbo car. For a bigger turbo, step up to an Xtreme-plate kit such as MB1-XTSS.
No. ACT describes the Heavy Duty plate as light to moderate pedal effort, so it feels close to a fresh factory clutch.
No. The kit includes the pressure plate, disc, release bearing and alignment tool. Resurface your flywheel or fit a new one at the same time.
Inspect the clutch fork, pivot ball and fork pin, which wear on DSMs. Check the rear main seal for leaks, replace any worn flywheel bolts, and bleed the hydraulics with fresh fluid.
Drive normally with plenty of stop-and-go shifting for the first few hundred miles before any launches or full-boost pulls, so the disc beds evenly into the flywheel and pressure plate.
