Yukon Gear V6/Turbo Differential 5.29 Ring & Pinion Gear Set For Toyota 8" Differential

For 1986–1995 4WD Toyota Pickup & 1986–1995 4WD Toyota 4Runner Equipped with Toyota 8" Differentials and 22R-TE or 3VZ-E Engines

Overview

The Yukon Gear 5.29 Ring & Pinion Gear Set is a premium differential upgrade engineered for Toyota 4WD trucks and SUVs equipped with Toyota's proven 8-inch rear differential. Featuring a deep 5.29:1 gear ratio and a heavy-duty 29-spline pinion design, this gear set is built to maximize low-speed torque, improve off-road crawling performance, restore drivability with oversized tires, and increase drivetrain strength in demanding conditions.

Whether you're building a dedicated trail rig, upgrading for 35-inch or larger tires, towing heavy loads, or improving the capability of your classic Toyota Pickup or 4Runner, Yukon gears deliver the durability, precision, and performance required for long-term reliability.

Manufactured using advanced machining processes, premium alloy steel, and industry-leading heat treatment techniques, Yukon ring and pinion gear sets are trusted by professional installers, overland builders, and off-road enthusiasts worldwide.

Why Choose 5.29 Gears?

The 5.29:1 ratio is one of the most popular gear upgrades for V6 and turbocharged Toyota applications running larger tires or operating in challenging terrain.

Performance Benefits

• Maximum low-speed torque multiplication

• Improved rock crawling capability

• Restores power lost from larger tire upgrades

• Enhanced throttle response

• Improved acceleration

• Reduced clutch and transmission strain

• Better towing and hauling performance

• Increased control in technical off-road terrain

For many Toyota owners running 35-inch tires or larger, 5.29 gears provide an excellent balance between trail performance, towing capability, and overall drivability.

Heavy-Duty 29-Spline Pinion Design

Unlike many factory Toyota gear sets that utilize a smaller 27-spline pinion shaft, Yukon engineers this gear set around a larger and stronger 29-spline design.

Advantages of the 29-Spline Upgrade

• Larger pinion shaft diameter

• Increased drivetrain strength

• Improved resistance to pinion failure

• Better durability under heavy loads

• Ideal for oversized tires and off-road use

• Improved long-term reliability

This upgraded design strengthens one of the most highly stressed components within the differential assembly.

Important 29-Spline Conversion Information

Please Read Before Ordering

Most 1986–1995 Toyota Pickup and 1986–1995 Toyota 4Runner applications originally came equipped with 27-spline pinion hardware.

Because this Yukon gear set uses a larger 29-spline pinion shaft, additional conversion components are required for installation.

Required Conversion Components

• 29-Spline Companion Flange / Yoke

• 29-Spline Pinion Seal

• 29-Spline Pinion Nut

These components are included when selecting:

"29-Spline Gears + 27-to-29 Spline Conversion Hardware Kit"

under the Installation Spline Configuration option.

This package provides everything required to convert a factory 27-spline setup to the stronger 29-spline Yukon configuration.
