Yukon Gear Master Differential Overhaul Kit | Toyota 8" V6 / Turbo 4WD (1986-95 4Runner / 1986-95 Pickup)

Yukon Gear Toyota 8" V6 / Turbo Master Differential Overhaul Kit

For 1986–1995 Toyota 4Runner and Pickup 4WD with the Toyota 8" V6/Turbo-style rear differential

Overview

The Yukon Gear Master Differential Overhaul Kit provides the bearings, races, seals, shims, and setup hardware required to rebuild the heavy-duty Toyota 8-inch V6/Turbo rear differential used in 22R-TE turbocharged and 3VZ-E V6 applications.

This rear third member uses the larger V6/Turbo-style carrier-bearing arrangement with 50 mm carrier journals and an 83 mm carrier-bearing bore. Available configurations cover the factory-style 27-spline pinion and aftermarket 29-spline gearsets, with either a conventional crush sleeve or a solid pinion-spacer setup.

Key Features

• Master overhaul kit for the Toyota 8" V6/Turbo rear differential
• For 22R-TE Turbo and 3VZ-E V6 rear differential applications listed below
• Includes carrier bearings and races
• Includes pinion bearings and races
• Includes pinion seal and complete shim kit
• Includes ring-gear bolts, pinion nut, and differential setup hardware
• Supports 27-spline factory-style and 29-spline aftermarket pinion configurations
• Choice of standard crush sleeve or solid pinion spacer
• Uses the V6/Turbo-style 50 mm carrier journal / 83 mm carrier-bearing bore
• Suitable for differential rebuilds, ring-and-pinion installations, and locker upgrades

Pinion Spline Configuration

27-Spline – Factory Ring & Pinion

Select this configuration when retaining the factory-style V6/Turbo ring-and-pinion. The original 1986–1995 V6/Turbo rear differential uses the 27-spline pinion configuration.

29-Spline – Aftermarket Ring & Pinion

Select this configuration only when installing a matching aftermarket 29-spline Toyota V6/Turbo ring-and-pinion set. A 29-spline conversion requires the correct 29-spline pinion yoke and matching installation hardware for the selected gearset.

V6 / Turbo Carrier Configuration

The Toyota 8-inch V6/Turbo third member uses a larger carrier-bearing arrangement than the standard 4-cylinder Toyota 8-inch differential:

• 50 mm carrier journals
• 83 mm carrier-bearing bore
• V6/Turbo-style Toyota 8-inch carrier-bearing configuration

No 45 mm-to-50 mm carrier-bearing conversion is required when rebuilding the original V6/Turbo third member.

Pinion Spacer Configuration

Standard Crush Sleeve

Uses the conventional crush-sleeve method to establish pinion-bearing preload.

Solid Pinion Spacer Upgrade

Uses a solid spacer and shim-adjusted preload system in place of the conventional crush sleeve.

Fitment Notes

• Rear differential only.
• Toyota 8" V6/Turbo-style third member only.
• Factory 1986–1995 V6/Turbo rear differentials use the 27-spline pinion configuration.
• The 29-spline option is for a matching aftermarket 29-spline Toyota V6/Turbo ring-and-pinion setup.
• 29-spline conversions require the correct 29-spline pinion yoke and matching gear-installation hardware.
• Does not fit the standard 4-cylinder Toyota 8-inch third member.
• Does not fit the Toyota 7.5-inch IFS front differential.
• Toyota third members are commonly swapped; verify the installed differential and pinion spline count before ordering.
• Proper pinion preload, backlash, and gear-contact pattern must be established during installation.
• Professional differential setup is recommended.
