AISIN Clutch Master Cylinder (1984-95 4Runner)

AISIN Clutch Master Cylinder

For 1984–1995 Toyota 4Runner with Manual Transmission

Overview

AISIN clutch master cylinders are manufactured to original-equipment hydraulic standards for factory-style fit, function, and durability in Toyota 4Runner clutch systems. Three application-specific configurations cover the manual-transmission clutch hydraulic systems used across the 1984–1995 U.S.-market 4Runner range.

The correct configuration changes by generation and engine family. The early 2.4L applications use one configuration, the 1988–1989 3.0L V6 uses a separate first-generation V6 configuration, and 1990–1995 second-generation 4Runners use the later configuration with either the 2.4L 22RE or 3.0L 3VZ-E V6.

Key Features

• OE-standard hydraulic construction — manufactured for factory-style fit and clutch-hydraulic operation
• 5/8-inch bore — 15.875 mm hydraulic bore
• Precision-honed cylinder bore — supports smooth piston travel and consistent clutch actuation
• Corrosion-resistant cylinder treatment — helps protect the bore and cylinder body during long-term service
• High-heat EPDM seals — designed for durable hydraulic sealing and leak resistance
• Application-specific configurations — separates early 4-cylinder, first-generation V6, and later second-generation applications

Vehicle Fitment

All applications require a factory-style manual clutch hydraulic system.

Toyota 4Runner

• 1984 Toyota 4Runner – 1st Gen – 2.4L 22R – Manual – 4WD
• 1985–1989 Toyota 4Runner – 1st Gen – 2.4L 22RE – Manual – 4WD
• 1988–1989 Toyota 4Runner – 1st Gen – 3.0L 3VZ-E V6 – Manual – 4WD
• 1990–1995 Toyota 4Runner – 2nd Gen – 2.4L 22RE – Manual – 2WD / 4WD
• 1990–1995 Toyota 4Runner – 2nd Gen – 3.0L 3VZ-E V6 – Manual – 2WD / 4WD

Fitment Notes

• Match the selected configuration to the vehicle year and engine family shown above.
• 1984–1989 2.4L 4-cylinder models use the early 4-cylinder configuration.
• 1988–1989 3.0L V6 models use the first-generation V6 configuration.
• 1990–1995 2.4L and 3.0L second-generation 4Runners use the same later configuration.
• The 22R-TE turbocharged 4Runner is excluded because U.S.-market turbo 4Runners were not offered with a factory manual transmission.
• For engine- or transmission-swapped vehicles, match the master cylinder to the installed clutch-hydraulic configuration rather than chassis year alone.
• After installation, bleed the clutch hydraulic system completely and inspect the AISIN Clutch Slave Cylinder, hose, and hard line for leakage or deterioration.
