The optional Level Pro self-leveling feature uses vehicle ride height sensors at each corner. The sensors contain an electrical rheostat that sends a variable chemical signal from 0-5 volts to the ECU, which then signals air valves to feed air from the onboard air reservoir to maintain-or alter-vehicle ride height as needed. The total range of adjustment is 6 inches. The sensors must be affixed to the frame with the suspension at midtravel (3 inches from full compression). The end links between the upper control arm and sensor lever are made from flexible synthetic rubber for easy mounting. The system runs at 130 to 150 psi and uses a combination of hard Teflon air feed lines and brass fittings to route the air.The optional Level Pro self-leveling feature uses vehicle ride height sensors at each corn The front Shockwave air-spring units feature built-in shock absorbers with dual damping adjustment knobs. Each knob has 16 individual settings and between them, 256 compression/rebound combinations are possible. Rod says the best place to start is to set the compression knob at 3 and the rebound knob at 8.The front Shockwave air-spring units feature built-in shock absorbers with dual damping ad At the rear of the car, the stock coil springs dropped right out after the shock absorbers were removed. It is best to swap one control arm at a time rather than pull all four and deal with a flopping rear axle as you work.At the rear of the car, the stock coil springs dropped right out after the shock absorbers Like the front control arms, the Street Challenge kit includes superior tubular steel replacements. A major cause of axle hop on GM A-bodies is flexing of the stock U-channel control arms and bushing compression. Strong Arms feature 0.188 wall thickness and polyurethane bushings for rigidity. The tubular upper control arms are more compact than OE arms, yielding added clearance for large-diameter exhaust pipes in this chronically tight area.Like the front control arms, the Street Challenge kit includes superior tubular steel repl The control arm installation was very straightforward. If your A-body is a Buick, Olds, or Pontiac, chances are the rear axle is a BOP-style 10-bolt with capped coil spring pads. They must be decapitated as shown to accept the bottom end of the rear air spring. Chevy-sourced '64-'66 10- and 12-bolt axles feature flat spring pads that are good to go without slicing.If your A-body is a Buick, Olds, or Pontiac, chances are the rear axle is a BOP-style 10-b The stock rear coil springs gave way to Cool Ride air springs with separate adjustable shock absorbers. The upper ends of the air springs fit into the frame pockets and are retained by large cotter pins so they can't drop out during assembly. Once they're in place, it's simple to lift the axle with a jack and install the rear shocks so they are trapped in position.The stock rear coil springs gave way to Cool Ride air springs with separate adjustable sho Like the Shockwave air spring / shock absorber combinations used at the front suspension, the individual rear shock absorbers supplied with the Street Challenge kit feature dual 16-position compression / rebound adjustment knobs. Get started by setting the compression knob (left) at 1 and the rebound knob (right) at 3.Like the Shockwave air spring / shock absorber combinations used at the front suspension, Part of the Street Challenge recipe for superior handling is a 1-inch solid steel Muscle Bar rear sway bar. It bolts directly to the lower control arms and works in conjunction with the front sway bar to fight body roll in hard corners.Part of the Street Challenge recipe for superior handling is a 1-inch solid steel Muscle B « | 1 | 2 | 3 | 4 | » | View Full Article Enjoyed this Post?
