Features:
- Trail-Creeper Super Finished 29-Spline Ring and Pinion Gear Set with 29-Spline Flange Kit - 4.88 Gear Ratio V6
- Made from tool-grade 8620 steel and heat-treated for maximum strength and wear resistance
- 29-Spline pinion spline is 7 percent larger in diameter than the 27-spline for increased strength
- Available in 4.88 and 5.29 ratios for 4-cyl, V6, and high pinion applications
- Requires Ring and Pinion Setup kit to complete the installation into your existing differential housing
- Gear teeth are cut using Gleason CNC hobbing machines and cutters
- No break-in period
- Less friction
- Reduced wear allowing bearings and gears to last longer
- Treated with REM Isotropic Super Finishing (ISF) process
- The REM Isotropic Super Finishing (ISF) process removes the microscopic peaks in the material and creates a surface on the ring and pinion gears with a roughness of less than 10 ?in Ra! This means that there is less friction between the gears, reducing wear by 95 percent and allowing the gears and bearings to run cooler and last longer
- Non-directional surface that increases lubricant retention on the gear surface, reducing lubrication requirements
- Flange is Quadruple drilled with the most popular Pickup/4Runner and Tacoma Patterns:
- 66mm x 66mm x 11mm (Tacoma)
