Product Description
The Revolution Gear & Axle T8.4-529 ring & pinion set is engineered to enhance torque and drivability for Toyota Tacoma owners running the 8.4-inch rear differential. The 5.29:1 ratio improves off-road performance, towing capability, and response with larger tires.
Constructed from high-grade 8620 alloy steel and heat treated for durability, the gear set features precise lapping for smooth operation and long life. It is ideal for lifted or loaded Tacomas, offering reliable performance under heavy loads and challenging conditions.
Installation should be performed by a qualified technician. Proper setup of bearing preload, backlash, and gear pattern is required. While the gear set comes pre-lapped, correct installation ensures optimal performance. Fitment is confirmed through 2015; coverage for 2016–2025 is unconfirmed at the time of listing.
*Parts are for USA spec vehicles, please contact us to verify fitment on JDM & international models.
