ACT HDG4 Sprung 4-Pad Race Clutch Kit | 4-Cylinder (1989-95 Pickup)

ACT HDG4 Heavy Duty Sprung 4-Pad Race Clutch Kit

For 1989–1995 Toyota Pickup 4-Cylinder Manual Transmission Models

Overview

The ACT HDG4 Heavy Duty Sprung 4-Pad Race Clutch Kit pairs a Heavy Duty pressure plate with a ceramic race disc for 3rd Gen Toyota Pickup builds that demand increased clutch holding capacity.

Three selectable applications make it easier to match the kit to your truck. The early applications cover both drivetrains, while the later trucks are separated into 2WD and 4WD configurations.

Designed for race-focused use, the HDG4 has aggressive engagement and prioritizes performance over everyday driving comfort.

Key Features

• Heavy Duty pressure plate with increased clamping force
• Four-pad ceramic disc for high heat tolerance
• Spring-centered hub to help absorb torsional loads
• Reinforced spring windows and retainers
• Dynamically balanced clutch assembly
• Release bearing, pilot bearing, and alignment tool included

HDG4 vs. HDSS

Choose the HDG4 when your build needs a ceramic race clutch and you accept abrupt takeup and possible gear rattle.

Choose the HDSS when smooth launches, daily driving, and progressive clutch control matter more. The HDG4’s sprung hub helps damp vibration, but it does not make the ceramic disc behave like the HDSS organic street disc.
