Bolt on Wheel-E-Bar, Chrome Round Tube Sprung, Competition Engineering has designed a bolt on version of our famous Wheel E- Bars specifically for street enthusiasts. Utilizing the same components as our Professional Wheel-E-Bars we were able to adapt them for street use by replacing the weld in ounting brackets with bolt on brackets. Bolt-on Design, no welding required, Triple process, show quality, chrome plated finish. 44" overall length, 18 5/8" center to center mounting bracket distance, Includes all hardware and mounting instructions. Can I use a Bolton Style Wheel E-Bar for Racing? This Bolt-On Wheel-E-Bar are intended for a Pro Street look, they contain many of the same components used in the Weld-On Wheel-E-Bars for racing. In fact , only difference is the bracketry which in its bolt-on configuation is not strong enough to control the vehcile in a wheelstand. By removing the clamp bracket and welding the axle bracket directly to the housing, you have a Wheel-E-Bar suitable for both street and Drag Race use. Bolt-On Chrome Round Tube Wheel-E-Bar™, Sprung • Bolt-On design, no welding required • Round tube design • Triple process, show quality, chrome plated finish • Available in sprung and unsprung versions • 44" overall length • 18-5/8" center to center mounting bracket distance • Includes all hardware and mounting instructions • Synthetic Rubber Wheels Wheelstands may look spectacular but they can actually hurt performance. Although some front end lift is beneficial to weight transfer, excessive lift can hurt. When a car wheelstands upon initial launch, it uses up power that could propel the vehicle forward. This results in slower ET's. As tire technology and horsepower levels progressed over the years, racers experimented with different ways to combat the wheelstanding problem. Most of the original designs consisted of merely bars or leaf springs that were welded directly to the rear end housing, hoping that they would prevent the front of the car from rising too high. One of the major problems with these early designs is that they caused the rear tires to unload resulting in a loss of traction. Competition Engineering recognized this problem long ago and developed a series of Wheel-E-Bars™ designed to limit and control big wheelstands without unloading the rear tires. We accomplish this by utilizing an axle housing mounted bracket that allows the Wheel-E-Bar™ to react instantaneously with rear housing movement. As the rear housing rotates, the natural rubber wheels come in contact with the track. The shock of this contact is absorbed by both the lower aluminum struts and the coil spring upper struts which keep the tires from unloading. As the housing continues to rotate more and the front end begins to lift, the coil springs on the upper struts start to compress. The more that the springs are compressed, the more force they exert converts the rotational energy into forward motion, resulting in quicker ET's. Competition Engineering has designed a bolt-on version of our famous Wheel-E-Bars™ specifically for street enthusiasts. Utilizing similar components as our Professional Wheel-E-Bars™ we were able to adapt them for street use by replacing the weld-in mounting brackets with bolt-on brackets. Offered in two different styles, aluminum strut or round tube lower link, now both street machiners & street rodders alike can have the race car look.
