Toyota 8.0 Inch V6 4.56 Ratio 29 Spline Ring and Pinion Revolution Gear 03-23 Tacoma / 16-23 4Runner
When tire size increases, gearing must follow. The Revolution Gear and Axle 8″ 29-Spline Ring & Pinion Gear Sets are engineered to deliver optimized drivetrain performance for 2003–2023 Toyota Tacoma models equipped with an 8″ rear differential and 29-spline axle shafts.
Available in 4.56, 4.88, and 5.29 ratios, these gear sets are designed to restore lost mechanical advantage caused by larger tire upgrades while improving throttle response and low-speed torque delivery. The 4.56 ratio offers a balanced upgrade for moderate tire increases, the 4.88 provides stronger torque recovery for daily-driven builds with larger tires, and the 5.29 ratio maximizes crawl performance and acceleration for heavier or more aggressive off-road setups. Precision-machined, heat-treated alloy steel construction ensures consistent gear mesh, reduced noise, and long-term reliability. Whether improving towing capability, adjusting shift points, or building a trail-focused Tacoma, these Revolution Gear ring-and-pinion sets provide dependable rear differential performance.
