Traction Bars for Trucks & Cars

What Do Traction Bars Do?

Traction bars control axle wrap, the twisting motion your rear axle makes when torque loads the springs on a hard launch. When leaf springs wind up, the axle rotates, the tires lose and regain grip, and you feel it as wheel hop. A traction bar limits that rotation, so the springs hold their shape and the tires stay planted.

That control pays off every time you get on the throttle. You get more consistent launches, less wheel hop, and less chance of the car pulling to one side as the springs load. Traction bars work on cars and on street, off-road, gas, and diesel trucks, including rigs that tow.

Types of Traction Bars We Carry

You can choose from vehicle-specific kits and universal traction bars for leaf-spring and coil-spring rear suspensions. Here's what's in the lineup:

• Calvert Racing Caltracs traction bar kits for 1964-65 Falcon and 1967-73 Mustang, 1963-76 Dodge Dart, Swinger, and Demon, and 1968-71 Fairlane.
• Caltracs kits for 1967-69 and 1970-81 GM F-body cars and the 1974 Charger, plus CalTracs MX kits.
• Competition Engineering leaf-spring traction bars for 1970-81 Camaro and Firebird, along with coil-spring traction bars.
• Competition Engineering Slide-A-Link for 1967-69 Camaro and Firebird.
• Lakewood heavy-duty universal traction bars in a 30" length for custom fitment.
• BMR Suspension anti-wheel hop kit for the 2004-05 Cadillac CTS-V.

Match the kit to your exact year, make, and model whenever a direct-fit option exists for your car or truck. Vehicle-specific kits are built around one chassis, while universal bars give you more flexibility on swaps and custom builds.

Traction Bars for Trucks: Towing, Lifted, and Diesel Builds

Traction bars for trucks keep the rear axle in check when you're towing, running a lift, or putting down diesel torque. Duramax, Power Stroke, and Cummins engines make heavy torque, and leaf springs can wind up under that load, especially with a trailer hitched. Traction bars limit that axle wrap, so your truck pulls straight and the tires stay hooked.

Lifted trucks deal with the same problem. Taller tires and lift springs give the axle more leverage to twist, so wheel hop can show up sooner. Rough Country offers a traction bar kit for 5-6-inch lifts that's built for that setup.

For heavy-duty 4wd pickups, Tuff Country makes traction bars for 2003-11 Dodge Ram 2500/3500 4wd and 1988-98 GM 1500/2500/3500 4wd trucks. Off-road trucks benefit too, since a controlled axle helps the tires keep climbing on loose ground. Before you order, confirm that your lift height, drive type, and spring style match the kit listing.

How to Choose the Right Traction Bar Kit

Start with your rear suspension type, because leaf-spring and coil-spring applications use different bar designs. From there, decide whether a vehicle-specific traction bar kit or a universal setup fits your project better. Run through these checks before you add a kit to your cart:

• Match the bar design to your leaf-spring or coil-spring rear suspension.
• Pick a vehicle-specific kit for a direct fit, or universal bars for custom builds.
• Check the overall length so the bar fits the space under your spring.
• Filter by mounting hardware included if you want a complete bolt-on package.
• Use the position and body type filters to confirm the bar suits your vehicle.

Think about how you use the vehicle, too. A street car that sees the occasional launch has different needs than a truck that tows every weekend. Universal bars take a little more fitting work, so read our guide on how to install traction bars before you start.

Traction Bars vs. Ladder Bars and Wheelie Bars

Traction bars are simpler bolt-on designs that control axle wrap while keeping your factory springs in place. Ladder bars mount at two points on the axle, one above and one below, for more rigid control of axle movement. That rigidity suits dedicated drag builds, while traction bars fit cars and trucks that still rack up street miles.

Wheelie bars handle a different job. They mount behind the rear axle and keep the front end from lifting too high on launch, a common need on high-power drag cars. Shop wheelie bars if your launches are already lifting the front tires.

If you're weighing a full rear suspension upgrade, our tech article on 4-link rear suspension vs. ladder bars breaks down the tradeoffs. It helps you decide when bolt-on traction bars are enough and when your build calls for more. Either way, start with how much power you make and how often you drive on the street.
