This is probably the most budget-friendly air ride kit on Earth, with 4-corner control (FBSS) for more ‘play time,’ better handling, & more security. Plus no wiring hassles with our great, manual valves. So track it, trip it, & trailer it at an affordable price. Simplicity over speed.
Choose your Classic GM vehicle that has four (4) coil springs listed in our Buick, Cadillac, Chevy cars, Oldsmobile, Pontiac, or Chevy / GMC C10 1963-1972 with four (4) coils in the Air Bag Kits dropdown along the top of the page. If you have a 1963-1987/91 C10/20/30 with rear leafsprings, our Official Rules explain how we can credit this prize value toward a system for your truck.
Analog System: Manual Paddle Control
Built for the purist who demands a direct, mechanical connection to their suspension, this system strips away the digital clutter—no finicky ride-height sensors, no self-leveling headaches, and absolutely no electrical gremlins.
Instead of fighting an operating system to get your car to sit right, you are in total command using dash-mounted mechanical paddle valves. Operation is instinctive and bulletproof: lift the lever to air up, or push it down to drop it low or lay it out, releasing the pressure with a distinct pneumatic hiss. By combining classic needle gauges with raw, physical control, this predictable setup puts you in absolute control of your ride height without electronics getting in the way.
Highlights:
- Bolt-On Simplicity: Front and rear powder-coated brackets are engineered to utilize your chassis’ existing mounting points or factory spring seats. No heavy fabrication or welding is required for the standard installation, making it a true garage-friendly upgrade for classic builds.
- Maximum Stroke Premium Airbags: Engineered for extreme stance and structural integrity. Our custom bags compress down to a razor-thin 2.8″ to achieve a completely slammed profile, and extend to a massive 10.8″—delivering nearly 8 full inches of usable stroke and a 600 PSI burst rating for unmatched pressure capacity.
- Exclusive 6+ Gallon Air Tank: Forget standard 4-to-5 gallon setups that leave you waiting around. We include our exclusive, high-capacity 6+ gallon tank to give you maximum air volume, faster recovery times, and plenty of reserve for when you want to play with the switches.
- Premium Heavy-Gauge Wire Package: Power your compressor reliably with heavy-duty, 8-gauge UL-listed power wire, complete with an integrated 40-amp Maxi fuse assembly to ensure proper circuit and system protection right out of the box.
- Spare Air Roadside Relief Package: Ultimate peace of mind. This package features a tank quick-connect and a 20-foot air coil hose with an air chuck, allowing you to easily air up a flat tire or use your onboard air anywhere around the vehicle.
- Precision Plumbing Essentials: No hacked lines or tedious leaks. We pair our premium DOT Brass air fittings with a dedicated tubing cutter for razor-sharp, square cuts and include high-performance airtight sealant to ensure a dependable, airtight seal.
