Tundra Gears & Driveline – Heavy-Duty Drivetrain Components for Towing & Larger Tires
When you upgrade to larger tires or start demanding more from your Tundra off-road, your factory gearing and driveline components can start to fall behind. Upgraded gears, driveshafts, and differential parts help restore lost power, improve throttle response, and keep your truck running strong under pressure. These parts are built for strength and reliability whether you're towing, crawling over rocks, or cruising on the highway. Re-gearing is especially important for lifted setups where performance and efficiency can suffer. To round out your build, pair your driveline upgrades with all-terrain Tires for optimal power delivery or check out our Lift Kits to take your suspension higher without sacrificing control.

Dial in Torque and Traction with Gearing and Driveline Upgrades for Your Toyota Tundra
When you add larger tires or start towing heavier loads, your factory gears and driveline components may not be enough to keep performance and fuel economy in check. Upgrading your Tundra’s gears, differentials, and driveline hardware helps restore power delivery, improves acceleration, and enhances off-road traction where it matters most.Why Regear Your Tundra?
- Regain lost torque and throttle response after installing oversized tires
- Improve towing stability and reduce strain on your transmission
- Optimize RPM ranges for better drivability on or off-road
- Increase fuel efficiency in certain load conditions
Supporting Driveline Upgrades
- Differentials: Add locking or limited-slip differentials for improved traction in mud, snow, or rocky terrain.
- Driveshafts: Aftermarket driveshafts improve durability and reduce vibration at higher speeds or under lifted suspension setups.
- U-joints and Yokes: Heavy-duty replacements help handle the added stress of off-road use or increased torque.
