Revolution Gear & Axle T8-456V6-29 4.56 Ratio Ring & Pinion for Toyota 8.0" V6

Vehicle Fitment

• Toyota vehicles with 8.0" rear differential (V6 or Turbo-charged engines, 29-spline pinion) - coverage includes many 2003-14 Toyota Tacoma, FJ Cruiser and Lexus GX470 applications; fitment beyond verified years is unconfirmed.

Features

• Optimized 4.56:1 gear ratio to reclaim performance when using larger tyres, added loads or aftermarket drivetrain changes.
• Ring & pinion gear set designed specifically for Toyota 8.0" differential housings (V6/Turbo engine versions) with 29-spline pinion.
• Manufactured from premium heat-treated 8620 alloy steel for durability under heavy duty or off-road use.
• CNC-machined and precisely lapped gears to provide quiet, smooth gear mesh and long life.
• No carrier break required in compatible 8.0" housing when installed correctly - simplifies upgrade process.
• Ideal for 4WD trucks/SUVs that are lifted, carry heavy loads or use oversized tyres where stock gearing is no longer optimal.
• Improves throttle response, climb capability and overall driveline efficiency by restoring proper engine-to-wheel ratio.
• Backed by a 2-year limited warranty against defects in materials and workmanship.

Product Description

The Revolution Gear & Axle REV-T8-456V6-29 ring & pinion set is designed specifically for Toyota vehicles equipped with the 8.0" differential housing paired to V6 or turbocharged engines using a 29-spline pinion. With a 4.56:1 ratio, this gear set restores optimal performance when larger tyres, heavier loads or drivetrain modifications push the factory gearing beyond its effective range.

Constructed from premium heat-treated 8620 steel and precision-machined for smooth engagement, these gears deliver quiet, reliable operation under demanding conditions. Ideal for off-road, towing or modified build applications, this gear set provides improved driveline response and efficiency.

Installation requires accurate setup - correct pinion depth, backlash and gear mesh are essential for long-term durability and quiet operation. Fitment is confirmed for appropriate Toyota 8.0" differential applications; coverage for every year/model is **unconfirmed** at the time of listing. Ensure your differential is the 8.0" housing with 29-spline pinion before purchase.
