UMI Performance UMI ABF806-1-B 68-72 A-Body Stage 3.5 Kit, 1 Inch Lower, Black

Stepping up from UMI's entry packages, this Stage 3.5 kit (ABF806-1-B) swaps in a rebound-adjustable monotube shock so damping can be dialed in after the 68-72 A-Body is back on the road, rather than locked to one setting. Spring rate holds at 530 lb/in with the same 1-inch drop at both ends, but Delrin bushings and caster-corrected geometry join the front control arms, while the rear trailing arms move to Roto-Joints with adjustable uppers for dialing in pinion angle. A solid 1.25-inch bar handles front sway, a black-finished solid 1-inch bar covers the rear, and a chassis stiffener rounds out the package. What's included Rebound-adjustable monotube shocks 530 lb/in coil springs Delrin-bushed, caster-corrected front control arms Roto-Joint rear trailing arms with adjustable uppers Before you order Rebound adjustment is the headline upgrade here compared with UMI's Stage 2 package, letting you tune ride feel instead of accepting a single valve setting. Ride height still comes down 1 inch at both ends, so the same clearance checks that matter for UMI's other A-Body kits apply to this one too. Common questions What sets this apart from UMI's Stage 2 kit? Rebound-adjustable shocks and Roto-Joint trailing arms replace the fixed-valve setup. How far does this kit drop ride height? 1 inch at both ends. What color is the rear bar? Black powder coat. Specifications KEY SPECS MFG.
