Bolt-On Dual Style Unsprung Wheelie Bar Kit for Drag Race and Performance Vehicles

The Granatelli Motor Sports GMWB19 is a universal bolt-on dual style unsprung wheelie bar kit designed for drag racing vehicles that need reliable rear stabilization without custom fabrication. At 44 inches in length with a 14-inch center-to-center wheel spacing, the GMWB19 provides a wide, stable stance that keeps the rear of the car planted through the full length of a pass. The chrome upper bars and natural billet aluminum lower construction deliver a clean, competition-ready appearance while keeping weight down. Solid rubber wheels absorb impact without bouncing or deflecting under hard launches. The GMWB19 installs with standard hardware over the rear axle housing on a wide range of drag vehicles.

Frequently Asked Questions

The GMWB19 is a universal bolt-on kit designed to fit a wide range of rear-wheel-drive drag race vehicles. It mounts to the rear axle housing using the included hardware and does not require welding or vehicle-specific brackets. Verify that your vehicle's rear axle housing geometry is compatible with the standard bolt-on mounting configuration before ordering.

An unsprung wheelie bar makes direct, rigid contact with the ground when the front wheels lift. This provides immediate, positive stabilization and is well suited for bracket racing and street-strip vehicles where predictable behavior is the priority. A sprung design uses a spring mechanism to absorb the impact of the front end dropping, which is preferred for higher-horsepower applications where abrupt contact could upset chassis balance. The GMWB19 is unsprung and is best suited for vehicles in the mid-range power category.

No. The GMWB19 is a bolt-on kit that attaches to the rear axle housing without welding, cutting, or custom fabrication. The included hardware and instructions support a straightforward installation with standard hand tools. This makes it a practical choice for racers who want to add wheelie bar protection without committing to permanent chassis modifications.

The GMWB19 measures 44 inches in total length with a 14-inch center-to-center wheel spacing. The 44-inch length provides enough extension behind the rear axle to catch the car at a safe angle during a wheelie, while the 14-inch width gives a stable two-point contact stance across the back of the vehicle.

Yes. The GMWB19 uses solid rubber wheels that are a standard wheelie bar wheel format. Replacement wheels are available through Granatelli Motor Sports and other drag racing suppliers. Inspect the wheels regularly for flat spots, cracking, or uneven wear and replace them as needed to maintain consistent contact and balance.

Wheelie bar requirements vary by sanctioning body and ET class. NHRA, IHRA, and local track rules each specify when wheelie bars are required or optional and may have minimum length requirements based on ET. Verify with your track or sanctioning body that the GMWB19 meets the applicable requirements for your vehicle class and elapsed time before using it in competition.

The upper bars on the GMWB19 have a chrome finish. The lower bars are natural billet aluminum. The combination provides a polished, competition-grade appearance while keeping the overall weight of the kit low. The chrome finish requires standard chrome care to maintain its appearance if the bars are exposed to moisture or track debris.

Yes, the Granatelli GMWB19 is a special order item. Allow additional lead time beyond standard in-stock products when ordering. Contact Black Ops Auto Works before purchasing if you have a specific event or deadline, so lead time expectations can be confirmed at the time of order.

Installation Instructions

1. Raise the vehicle safely on jack stands and support the rear axle housing independently.
2. Identify the mounting location on the rear axle housing per the included instructions. Clean the mounting surface of dirt, grease, and rust before installation.
3. Assemble the lower billet aluminum bars to the upper chrome tubes per the hardware diagram included in the kit.
4. Attach the wheelie bar assembly to the rear axle housing using the provided hardware. Do not fully torque fasteners until the alignment is set.
5. Install the solid rubber wheels onto the wheel hubs at each end of the lower bars and secure with the included hardware.
6. Adjust the height of the wheelie bars so the wheels contact the ground at the desired angle when the front wheels are at full lift. Most setups target a 2 to 4 inch ride height at the wheel contact point.
7. Torque all fasteners to specification and verify there is no flex or movement in the assembly before track use.
8. Make a slow-speed test pass to confirm contact angle and stability before making a full-power run.
