Product Description

The Revolution Gear & Axle T8IFS-456TR is a high-performance ring and pinion gear set designed for Toyota vehicles equipped with the 8.2" rear differential housing. Featuring a 4.56:1 ratio, this gear set is engineered to enhance low-end torque, improve off-road capability and better match larger tires or heavier loads/excess weight. Manufactured from premium 8620 steel and precisely gear-cut for smooth operation, it offers an excellent upgrade path for serious enthusiasts or heavy-use drivers.

Before purchasing or installing, confirm that your vehicle uses the Toyota 8.2" rear axle assembly, check the spline count, ring gear size, and that the differential is standard-rotation. While fitment listings reference 2010-23 Toyota 4Runner, Lexus GX460 and other models, full engine/trim/drivetrain/year confirmation (including 2024/25) is unverified. Installation should be carried out by a qualified differential specialist, with correct backlash, preload and break-in procedures to ensure optimal longevity.
