Revolution Gear & Axle T8-488 4.88 Ratio Ring & Pinion for Toyota 8.0" Different

Vehicle Fitment

• Toyota vehicles with 8.0" rear differential housing (standard-rotation) using 29-spline pinion - common in 1979-95 Toyota pickups and 1984-95 4Runner; coverage for later years or other axle variants is unconfirmed.

Features

• Optimized 4.88:1 gear ratio engineered for improved torque and driveline performance when larger tyres, heavier loads or aftermarket modifications are present.
• Ring & pinion gear set designed specifically for Toyota 8.0" housing (standard rotation, 29-spline pinion) - direct-fit replacement when correct axle confirmed.
• Manufactured from premium heat-treated 8620 alloy steel for long term durability and reliable service under heavy load or off-road use.
• CNC-machined and precisely lapped gear surfaces ensure smooth mesh, quiet operation and long lifespan.
• No carrier break required in compatible 8.0" housing when correct configuration is present - simplifies upgrade on appropriate vehicles.
• Ideal for overland, off-road lifted or heavy-haul Toyota builds where factory gear ratio no longer keeps up.
• Restores throttle response, hill-climb performance and towing/cargo capability by returning optimal engine-to-wheel ratio.
• Backed by a 2-year limited warranty against manufacturing defects.

Product Description

The Revolution Gear & Axle T8-488 ring & pinion set is built for Toyota vehicles equipped with the 8.0" rear differential housing and a 29-spline pinion. When larger tyres, added accessories or heavier loads push your drivetrain beyond what the factory gear ratio can support, this 4.88:1 upgrade restores performance and driveline balance by providing a stronger gear ratio without changing the carrier in compatible applications.

Constructed from high-grade heat-treated alloy steel and precision-machined with smooth gear surfaces and quiet running in mind, this gear set is an excellent choice for trucks or SUVs that are modified for off-road, towing or overland use. The installation becomes simpler when you have confirmed your axle specification is correct, as no carrier break is required when used in the correct Toyota 8.0" housing setup.

Installation is recommended for experienced technicians or professional shops - proper backlash, pinion depth and gear mesh are essential for long-term durability and quiet operation. Fitment is confirmed for the Toyota 8.0" differential housing with 29-spline pinion; fitment for alternate years, axle sizes or spline counts is unconfirmed at time of listing. Always verify that your vehicle's axle housing, spline count and rotation type match before purchasing.
