Powerful Front Brakes
A big part of controlling a trailer is having the ability to stop it. To that end, Tundra has the largest-in-class front brakes equipped with 4-piston brake calipers.1
Massive Ring Gear
To handle the torque of Tundra’s available i-FORCE 5.7L V8, our engineers fitted the rear differential with a massive 10.5-inch ring gear. This allows use of an aggressive 4.30 rear axle ratio to help amplify and transfer the 401 lb.-ft. of torque the 5.7L V8 produces to the ground.
i-FORCE 5.7L V8 (346 cu. in.)
381 hp and 401 lb.-ft. of torque, a 6-speed automatic transmission, plus a standard Tow Package with added engine and transmission oil coolers equal heavy-duty towing capability.2 Add Double Overhead Cams (DOHC), a 32-valve head design and Dual Independent Variable Valve Timing with intelligence (Dual Independent VVT-i), and you get an i-FORCE drivetrain that can tow a space shuttle.3
i-FORCE 4.6L V8 (281 cu. in.)
Tundra’s 4.6L V8 is packed with tech, delivers 310 hp and 327 lb.-ft. of torque via a 6-speed automatic transmission. It also benefits from Double Overhead Cams, a 32-valve head design and Dual Independent Variable Valve Timing with intelligence (Dual Independent VVT-i), so all the power you need is ready when you need it.
Automatic Limited-Slip Differential
Standard on all Tundras, Auto LSD4 works like a traditional limited-slip differential—with a high-tech twist. Instead of controlling slip mechanically, Auto LSD applies brakes individually to wheels with no traction. And unlike Traction Control, it doesn’t cut engine power. This helps give you control and distributes power where it’s most effective. Best of all, because the system utilizes the brake system, there are no extra components that add to overall ownership costs.
Active Traction Control
The added traction of 4WD is great—but with A-TRAC, it’s even better. A-TRAC is a 4WD traction control system that uses the 4-channel ABS system to control power flow to the front and rear wheels, all without cutting throttle input, to help make traction no matter where you may be.
Based on manufacturers’ data.
2 Before towing, confirm your vehicle and trailer are compatible, hooked up and loaded properly and that you have any necessary additional equipment. Do not exceed any Weight Ratings and follow all instructions in your Owner’s Manual. The maximum you can tow depends on base curb weight plus the total weight of any cargo, occupants, and added vehicle equipment. “Added vehicle equipment” includes additional standard/optional equipment and accessories added by the manufacturer, dealers, and/or vehicle owners. The only way to be certain of your vehicle’s exact curb weight is to weigh your vehicle without passengers or cargo.
3 The 2012 Tundra CrewMax 5.7L V8 is towing far beyond its published towing capacity in a one-time, short-distance event. Never tow beyond a vehicle’s published towing capacities. Always consult the Owner’s Manual.
4 Auto LSD is an electronic, brake-actuated limited-slip differential that automatically activates when VSC is disengaged at low speeds.
