Product Description

The Revolution Gear & Axle T7.5-488 is a 4.88 ratio ring and pinion set engineered specifically for the Toyota 7.5" standard rotation front differential found in 1984-1995 4Runner and 1986-1995 Pickup models. Built from 8620 alloy steel with precision heat treatment, this gear set is designed to restore or upgrade differential gearing for trucks running larger tires, helping correct engine RPM drop and restoring throttle response lost after a lift and tire upgrade.

Revolution Gear's controlled lapping process ensures quiet break-in and long gear life, making this set a top choice for both daily drivers and dedicated trail rigs. Professional installers favor Revolution gears for their consistent setup tolerances, which simplify backlash and preload adjustment during installation. A separate master install kit is recommended for a complete differential overhaul.
