The suspension of any pickup, van, or sport utility that’s weighed down by heavy cargo, permanently affixed equipment, or a trailer is compromised because the rear springs are crushed down to a height they cannot recoil from. Ride quality is reduced, and the front of your vehicle points upward. A rear end that is weighed down literally lifts weight off your front wheels, reducing the amount of traction you have for steering, and reducing the amount of grip the tires have on the road when you need it in fast braking. If you have lowered your vehicle with reduced height springs, the effect can be even worse
Belltech’s Air Jack Kit has been created just for trucks with lowered suspensions. A set of adjustable helper air springs mount between your vehicle frame and rear leaf spring to lift the weight that’s causing your pickup to ride lower than it should. Once your vehicle’s back up to a level ride height, headlights and bright lights stay at the correct aim so the road ahead of you is illuminated rather than the tree tops in the distance. And instead of putting yourself at risk by blinding other drivers, you can focus on avoiding potholes that are no friend to lowered vehicles. Air is added and released manually by a control switch that mounts inside your vehicle. For those that prefer the immediate responsiveness that a reserve of compressed air allows, a separate ½-gallon 10" x 6.75" x 14" storage tank is available.
Instead of searching for a gas station with a working compressor to fill your Air Jack helper springs by hand, Belltech offers you the convenience of power inflation wherever you go with an air compressor. After minor drilling, the compressor mounts permanently to the frame of your vehicle and is controlled from inside with the touch of a button. The compressor is produced under license by renowned specialists Viair, and features a 25% duty cycle rating, maximum working pressure of 150psi, and maximum draw of 18 amps. Because it’s designed to be compatible with any vehicle, it operates using standard 12-volt power sources. A built-in 25 amp circuit breaker guards against any electrical surges that may result from compromised wiring or other issues. ¼-inch air line fittings are of the highest quality brass construction with quick-disconnect couplings, and are Teflon coated for smooth, easy operation in any temperature or climate.416.50
Brand: Belltech Part Numbers:
Founded in 1983 in Fresno, California, Belltech Suspensions began with a mission of filling a need that existed in the marketplace for quality lowering kits that provided full-size pickups with an aggressive stance AND a ride that wasn’t severely punishing. After developing state-of-the-art drop spindles, coil springs, and shackle hanger kits, word of mouth spread about the design, reliability, and smooth operation of their products – earning Belltech respect among demanding California custom builders and racers. The consistent high quality and cutting edge functionality of their lowering kits allowed them to grow in the marketplace, and the company expanded to their current location in neighboring Sanger, CA. Belltech merged with German-based KW Suspensions in 2005, and today draws on a wealth of engineering talent that has produced joint products with automotive manufacturers such as AMG, Roush, and Viper and been involved in world class racing series. CARiD is proud to offer best values on the full lineup of Belltech quality air springs, compressors, coilover sets, lowering kits, shock absorbers, anti-sway bars, lift kits, and alignment kits which prove that lowered style and ride comfort are not mutually exclusive.
