Wheelie Bars & Kits

What Do Wheelie Bars Do in Drag Racing?

Wheelie bars do two jobs at once: they stop the front end from lifting during hard acceleration, and they help you control wheel speed and tune the suspension. When your tires hook hard off the line, the chassis wants to rotate and lift the nose. A wheelie bar limits that rotation, keeping the car level, safe, and pointed straight. That same contact point also lets you manage how quickly the rear suspension loads, which affects traction and consistency run after run. Racers use the bars as a tuning tool, softening or stiffening the hit to match track conditions. If you're shopping the broader system, browse the full Traction Bars & Wheelie Bars category to compare setups.

Types of Wheelie Bar Kits and Components

Wheelie bar options range from complete race-ready kits by Rhodes Race Cars, offered in Pro Series 80 in., Pro Mod 96 in., and Sportsman 70 in. lengths, to simple bolt-on kits like the dual-style 44 in. setup from Granatelli. Match the type to your car, budget, and class:

• Complete bolt-on wheelie bar kits that mount to the rear frame or axle brackets with basic hand tools.
• Universal Wheel-E-Bars you can adapt to many chassis without custom fabrication.
• Sprung designs that cushion the initial hit, versus unsprung designs that react instantly.
• Complete kits sized for everything from street/strip cars to dedicated Pro Mod combinations.
• Individual wheelie bar components such as struts, collars, billet aluminum arms, and mounting brackets.

How to Choose Wheelie Bar Length and Material

Choosing a wheelie bar comes down to length, material, and single- versus dual-bar design. Length typically ranges from about 44 in. up to 96 in.; longer bars react more gently and suit quicker, higher-horsepower cars, while shorter bars fit milder street/strip builds. Material matters for weight and strength: seamless steel tubing is durable and budget-friendly, while chrome moly is lighter and stronger for serious competition. Competition Engineering Wheel-E-Bars come in both bolt-on and universal versions using seamless steel and chrome moly tubes, so you can match the build to your class. Single-bar setups save weight and work well for lighter cars, while dual-bar designs add stability for high-power combinations that load hard. Wheel and tire choice affects how the car launches too, so review our guide on what size racing wheels to run for drag racing before you finalize your rear setup.

Wheelie Bar Markers and Track Accessories

Wheelie bar markers help you read exactly how your car behaves off the line. Also called wheelie bar chalk, these markers coat the bottom of your wheelie bar wheels so you can see how hard and how long the bars are loading against the track. That feedback tells you whether to raise, lower, or adjust the bars for better sixty-foot times. Allstar Performance offers wheelie bar markers that make this tuning quick between rounds. Pair your bars with the right supporting hardware, from mounting brackets to replacement wheels, to keep the system consistent. Remember that wheelie bars are only part of your traction package: how the rear suspension plants the tires matters just as much. If your car still spins or shakes despite good bars, add Traction Bars to control axle wrap and put more power to the ground.

How to Set Wheelie Bar Height and Adjustment

Start with your wheelie bar wheels about 2 to 4 inches off the ground at rest, then adjust from there based on how the car launches. Lower bars react sooner and control the front end more aggressively, while higher bars let the nose rise slightly before the bars take load. Rough or bumpy tracks often need higher bars so the wheels don't drag or bounce on imperfections. Make small changes, one at a time, and watch your wheelie bar markers and sixty-foot times to confirm the direction. Height, preload, and angle all interact, so record each change and its result. Because the bars work with the rest of your chassis, browse Chassis, Steering & Suspension parts to round out your setup. For step-by-step tuning help, our chassis and suspension tech articles walk through how these adjustments affect the whole car.
