Yukon Gear 5.29 V6/Turbo Differential Ring & Pinion Gear Set for Toyota 8" Differential 4WD (1986-95 4Runner/Pickup)

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 designed for Toyota 4WD trucks and SUVs equipped with the 22R-TE and 3VZ-E Toyota 8-inch rear differential. Featuring a deep 5.29:1 gear ratio and heavy-duty 29-spline pinion design, this gear set is engineered to maximize low-speed torque, improve crawling performance, restore power lost to oversized tires, and increase drivetrain durability in demanding off-road conditions. Built using precision machining, advanced heat treatment, and strict quality control standards, Yukon ring and pinion gear sets are trusted by professional installers, off-road builders, overland enthusiasts, and restoration shops. This 5.29 gear set is best suited for Toyota owners running larger tires, building dedicated trail rigs, or wanting stronger low-speed performance from classic 22R-TE and 3VZ-E powered trucks. Why Upgrade to 5.29 Gears? The 5.29:1 ratio is one of the deepest gear ratios commonly used in Toyota 8-inch differential applications. It is ideal for vehicles running oversized tires or spending significant time off-road. Performance Benefits Maximum low-speed torque multiplication Improved rock crawling capability Restores power lost from oversized tires Improved acceleration and throttle response Better clutch and transmission control off-road Improved drivability in steep or mountainous terrain Increased control during technical trail driving Strong choice for 34-inch and larger tire setups For Toyota owners prioritizing trail performance over highway efficiency, 5.29 gears provide excellent crawling control and low-speed drivability. Heavy-Duty 29-Spline Pinion Design Unlike many factory Toyota gear sets that use a smaller 27-spline pinion shaft, Yukon engineers this gear set around a stronger 29-spline pinion 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 larger tires and off-road use Improved long-term reliability This upgraded pinion design strengthens one of the most highly stressed areas of the differential. 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 hardware is required for installation. Required Conversion Components 29-Spline Companion Flange / Yoke 29-Spline Pinion Seal 29-Spline Pinion Nut These parts are included when selecting: 29-Spline Gears + 27-to-29 Spline Conversion Hardware Kit under the Installation Spline Configuration option. This package provides the required hardware needed to convert factory 27-spline applications to the stronger 29-spline Yukon setup. Precision Yukon Engineering Yukon Gear & Axle manufactures ring and pinion gear sets to strict standards for fitment, durability, and performance. Construction Features Precision-machined ring and pinion gears Advanced heat-treated alloy steel construction Optimized gear tooth geometry Premium surface finishing process Quality-tested gear tooth patterns Engineered for quiet operation Designed for long service life These features help ensure proper gear mesh, smooth engagement, and dependable long-term performance. Built for Off-Road & Heavy-Duty Use Yukon gear sets are designed to perform in demanding environments, from daily driving to extreme trail use. Durability Benefits High-strength gear construction Excellent wear resistance Designed for oversized tire applications Compatible with many locking differentials Proven performance under heavy loads Long-term drivetrain reliability This makes Yukon 5.29 gears an excellent option for trail builds, overland rigs, and restored Toyota trucks that need stronger low-speed gearing. Identifying the Correct Differential Housing 4-Cylinder vs V6/Turbo Third Members Toyota produced two different Toyota 8-inch differential housings. Selecting the correct gear set depends on which third member your vehicle is equipped with. Standard 4-Cylinder Housing Three external reinforcement ribs Found in most 20R, 22R, and 22RE applications Requires the Yukon 4-Cylinder gear set V6/Turbo Housing Four prominent reinforcement ribs Distinct trapezoid-shaped upper rib Found in most 22R-TE and 3VZ-E applications Uses this gear set Quick Visual Identification Look at the outside of the third member housing: 3 Ribs = Standard 4-Cylinder Differential 4 Ribs + Top Trapezoid Rib = V6/Turbo Differential If your vehicle is equipped with a factory 4-Cylinder third member, use the Yukon 4-Cylinder-specific gear set instead.

This Yukon gear set is not compatible with those factory carrier configurations without converting to a standard Toyota 8-inch carrier and third-member assembly. 📊 Gear Ratio to Tire Size Matrix Applies to 1979–1995 Toyota Pickups & 4Runners with factory 20R, 22R, 22R-E, 22R-TE or 3VZ-E engines. Tire Size Best All-Around Ratio Drive Style / Terrain Guidance 30" Tires 4.11 (Factory Stock) Stick with factory 4.11s for flat highway commuting. Bump to 4.56 if the truck carries heavy overland gear or works in hilly regions. 31" Tires 4.56 The Restorer Sweet Spot. 4.56 perfectly corrects the speedometer and restores factory acceleration without over-revving on the highway. 32" Tires 4.88 (Performance) Choose 4.56 if you prioritize maximum highway fuel economy. Choose 4.88 if you want crisp acceleration around town and extra trail torque. 33" Tires 4.88 The Weekend Warrior Standard. 4.88 keeps the truck comfortable at 70 MPH while waking up the engine's low-end crawl power. 34" Tires 5.29 Highly recommend 5.29. The narrow power band of the 22RE/3VZE requires the deeper mechanical advantage of 5.29s to pull 5th gear. 35" Tires 5.29 The absolute limit for standard axles. 5.29 keeps the small engine in its optimal high-power RPM band to handle massive rolling mass. 35"+ (37" to 40") 5.29 + Dual Cases 5.29 is the lowest safe differential ratio. For tires larger than 35", builders must combine 5.29 gears with a crawler box/dual transfer case setup Available Configurations Standard Gear Set Includes: (1) Yukon 5.29 Ring Gear (1) Yukon 5.29 Pinion Gear Installation Instructions Gear Set + 29-Spline Conversion Hardware Kit Includes: (1) Yukon 5.29 Ring Gear (1) Yukon 5.29 Pinion Gear (1) 29-Spline Companion Flange / Yoke (1) 29-Spline Pinion Seal (1) 29-Spline Pinion Nut Installation Instructions This option provides the necessary hardware required to convert factory 27-spline applications to the stronger 29-spline Yukon setup.
