Drivetrain Parts & Upgrades for Toyota Trucks
Upgrade your Toyota's drivetrain with gears, axle components, differential upgrades, and transfer case parts built for off-road performance. We carry drivetrain solutions for Toyota Tacoma, 4Runner, Tundra, FJ Cruiser, and Land Cruiser from brands like Yukon Gear & Axle, Nitro Gear, ARB, and more.
After installing larger tires, re-gearing your differentials is one of the most impactful upgrades you can make. Proper gear ratios restore lost power and fuel economy, giving your truck the torque it needs to turn bigger rubber confidently on the highway and the trail.
Key Drivetrain Components
- Ring & pinion sets: Re-gear for larger tires — 4.56, 4.88, and 5.29 ratios are popular for Toyota trucks
- Lockers & limited-slip differentials: ARB air lockers, Eaton e-lockers, and Yukon Grizzly lockers for maximum traction
- Axle shafts: Chromoly and upgraded CV axles for trucks with significant lift and larger tires
- Transfer case gears: Dual and low-range gear sets for improved crawl ratios

Frequently Asked Questions
Do I need to re-gear after installing bigger tires?
If you increase tire size by more than 1-2 inches, re-gearing is strongly recommended. Larger tires effectively lower your gear ratio, making the engine work harder at highway speeds and reducing acceleration. Re-gearing restores the factory power band and can actually improve fuel economy compared to running stock gears with oversized tires.
What gear ratio should I choose for 33-inch tires?
For most Toyota trucks running 33-inch tires, 4.56 or 4.88 gears are popular choices. If you have a manual transmission or primarily drive off-road, 4.88 gives better low-end torque. For daily drivers with an automatic, 4.56 provides a good balance of performance and fuel economy.
What is a differential locker and do I need one?
A locker forces both wheels on an axle to spin at the same speed, providing maximum traction in off-road conditions. Factory limited-slip differentials slip under extreme conditions. If you do serious trail driving, a selectable locker (like an ARB air locker) in the rear is one of the best traction upgrades you can make.
