Product Description

The Revolution Gear & Axle T8-529 ring & pinion gear set is engineered for Toyota 8.0" differential applications in older trucks and SUVs. The 5.29:1 ratio delivers improved torque, strong axle engagement, and enhanced off-road performance.

Manufactured from heat-treated 8620 steel and precision-machined for smooth operation, this gear set provides durability and reliability for restoration or upgrade projects. It simplifies installation when replacing like-for-like in stock housings.

Fitment is confirmed for 1979-1995 Toyota Pickup and 1984-1995 Toyota 4Runner equipped with 8.0" differentials. Coverage beyond these years is unconfirmed at time of listing. Verify differential housing, splines, and rotation before installation.
