ACT HDSS Performance Street Clutch Kit | 4-Cylinder (1984-95 4Runner)

ACT HDSS Heavy Duty Performance Street Clutch Kit

For 1984–1995 Toyota 4Runner 2.4L 22R / 22RE Manual Models

Overview

The ACT HDSS Heavy Duty Performance Street Clutch Kit combines a heavy-duty pressure plate with a sprung, full-face organic performance street disc. The design increases clutch holding capacity while retaining smooth, positive engagement and a light-to-moderate pedal feel suitable for street-driven and off-road Toyota 4Runners.

This listing covers multiple application-specific configurations for naturally aspirated 2.4L 4-cylinder 4Runners. Choose the configuration by model year and drivetrain, as clutch sizing and fitment differ between 1st Gen and 2nd Gen models.

Key Features

• Heavy Duty pressure plate designed for increased clamp load and reduced diaphragm deflection.
• Sprung full-face organic Performance Street clutch disc for smooth, positive engagement.
• Light-to-moderate pedal effort for street-friendly drivability.
• Steel-backed organic friction material provides improved heat capacity and durability.
• Pressure plate assemblies are clamp-load tested and dynamically computer balanced.
• Designed for increased torque capacity over the factory clutch while maintaining an organic street-disc configuration.

HDSS vs. HDG4

Choose the HDSS when smooth launches, daily driving, and progressive clutch control are your priorities.

Choose the HDG4 when your build needs a ceramic race clutch and you accept abrupt takeup and possible gear rattle. The HDG4’s sprung hub helps damp vibration, but it does not provide the smooth engagement of the HDSS organic street disc.
