The SC&C Performance Package Chassisworks Billet is perfect for those who want a fantastic, comprehensive performance handling package. We`ve hand-picked the best muscle car performance handling car parts in the business and combined them into one awesome package.
For the `64-`72 A body package, we start off by fixing the weakest link in the chain, the horrible stock front suspension geometry. Our Chassisworks Billet tall aluminum spindles take care of this by relocating the suspension pickup points to achieve correct negative camber gain in bump for better grip, a higher and much more stable roll center for reduced body roll and more predictable handling, and with the A body specific aluminum steering arms, virtually no bump steer. These spindles feature no drop in ride height. The revised geometry of the Chassisworks Billet package is a real game changer! We round this part of the package out with easily adjustable SPC Performance tubular upper A arms (now in Black e-coat finish). Our Performance Package Chassisworks Billet also includes SPC tubular lower control arms, with lower ball joints installed, an SPC ride height adjustment kit, and a pair of SPC progressive rate jounce bumpers. This gives you ride height adjustability, and lets you nail a perfect modern alignment.
We add firmness and control, as well as a more aggressive stance, with SPC Performance Pro kit springs. We add adjustability with Varishock QS1 single adjustable shocks. We add chassis rigidity with our SC&C HD chassis brace.
Out back we prevent excessive rear axle migration under load, and reduce unwanted binding, with Currie Currectrac aluminum severe duty arms. Billet aluminum lowers , with adjustable uppers. They are stronger and more visually striking than anything else out there.
We round out the package with sway bars. No cookie cutter bars here. We include state of the art 4130 tubular chrome moly bars from Hellwig. The rear bar is a whole new format for this car, mounting to the chassis with links to reduce unwanted binding, and provide much more usable rate than bars mounted to the lower trailing arms. It is also adjustable for street / autocross/ or drag racing. It adds a LOT of performance and versatility but hardly any weight, the bar only weighs about 6 lbs.! We match it with a Hellwig/SC&C thin wall tubular front sway bar with SC&C Extreme duty end links, for excellent wheel/tire clearance, and a weight of only 14 lbs.! The weight of both bars combined is 14 lbs. LESS than a 1 5/16” solid front bar alone!
Combine this package with a good wheel/tire combo and upgraded brakes and you have a vintage muscle car with modern performance car handling and drivability!
