AISIN Clutch Master Cylinder | Manual Transmission (1984-95 4Runner / Pickup)

AISIN Clutch Master Cylinder

For 1984–1995 Toyota 4Runner and Toyota Pickup manual-transmission applications with 2.4L R-series or 3.0L 3VZ-E engines, as detailed below.

Overview

AISIN builds these clutch master cylinders to original-equipment hydraulic standards for factory-style fit, function, and durability in classic Toyota 4Runner and Pickup clutch systems. Each configuration is matched by model year and engine family so the correct hydraulic cylinder can be selected without relying on a one-size-fits-all replacement.

Precision-honed hydraulic bores, corrosion-resistant cylinder-body plating, and high-heat EPDM seals are designed to provide smooth clutch-pedal operation, reliable hydraulic pressure, and long service life.

Key Features

• Original-equipment-standard engineering — designed for factory-style hydraulic fit and function
• 5/8-inch bore — 15.875 mm hydraulic bore across the listed configurations
• Precision-honed cylinder bore — supports smooth piston travel and consistent clutch actuation
• Corrosion-resistant finish — anodized and nickel-phosphorus-plated cylinder surfaces support smooth operation and durability
• High-heat EPDM seals — engineered for hydraulic sealing durability and leak resistance
• Direct-replacement design — three fitment-specific configurations cover the Toyota applications below

Vehicle Fitment

All applications require: Manual transmission.

Toyota 4Runner

• 1984 | 1st Gen — 2.4L 22R
• 1985 | 1st Gen — 2.4L 22R / 22RE
• 1986–1988 | 1st Gen — 2.4L 22R / 22RE / 22R-TE
• 1989 | 1st Gen — 2.4L 22RE or 3.0L 3VZ-E V6
• 1990–1995 | 2nd Gen — 2.4L 22RE or 3.0L 3VZ-E V6

Toyota Pickup

• 1984 | 2nd Gen — 2.4L 22R
• 1985–1988 | 2nd Gen — 2.4L 22R / 22RE / 22R-TE
• 1989–1990 | 3rd Gen — 2.4L 22R / 22RE
• 1990–1995 | 3rd Gen — 3.0L 3VZ-E V6
• 1991–1995 | 3rd Gen — 2.4L 22RE

Fitment Notes

• Match the configuration to both the vehicle year and engine family.
• The early 2.4L configuration covers 22R / 22RE applications and 22R-TE turbo manual applications within its listed year range.
• For 3.0L 3VZ-E applications, use only the V6 configuration and follow its listed 4Runner and Pickup year range.
• For engine-swapped vehicles, match the master cylinder to the installed drivetrain and clutch-hydraulic configuration rather than chassis year alone.
• After installation, bleed the clutch hydraulic system completely and inspect the slave cylinder, hose, and hard line for leakage or deterioration.
