A 73-87 C10 air suspension kit replaces traditional coil springs with airbags, allowing adjustable ride height and stiffness. This customization absorbs road imperfections, reduces body roll, and enhances comfort. Drivers can tailor pressure settings for loaded vs. unloaded conditions, optimizing handling and reducing wear on tires and chassis components.
What Components Are Included in a Typical C10 Air Suspension Kit?
Most kits include air springs (front and rear), compressors, valves, air tanks, lines, and a control system (manual or digital). Premium kits add shock absorbers, reinforced mounting hardware, and pressure sensors. Brands like AccuAir and Air Lift often bundle corrosion-resistant parts for durability in harsh conditions.
When selecting components, consider the compressor’s duty cycle and air spring load capacity. Single-compressor systems work for occasional adjustments, while dual compressors handle frequent height changes. Air line diameter also matters—3/8-inch lines provide faster inflation than 1/4-inch alternatives. Below is a comparison of common configurations:
| Component | Basic Kit | Performance Kit |
|---|---|---|
| Compressor Type | Single | Twin |
| Air Line Size | 1/4″ | 3/8″ |
| Control Interface | Manual switches | Touchscreen |
How to Install a 73-87 C10 Air Suspension Kit: Step-by-Step Guide
1. Disconnect the battery and remove old springs/shocks.
2. Mount airbags using provided brackets, ensuring clearance for steering components.
3. Route air lines away from heat sources and sharp edges.
4. Install compressor and tank in a dry location (under bed or inside frame rails).
5. Wire the control system and test for leaks with soapy water.
For optimal results, use a digital angle finder when positioning airbag brackets to maintain proper suspension geometry. Reinforce mounting points with grade-8 hardware if planning heavy towing. When routing lines through frame channels, use split loom tubing to prevent abrasion. Allow 10-12 hours for a professional-grade installation, including these key tools:

Which C10 Models Are Compatible with Aftermarket Air Suspension Kits?
Kits are designed for Chevrolet C10 trucks from 1973 to 1987, including fleetside and stepside beds. Compatibility varies by cab configuration (regular or extended) and drivetrain (LS swaps may require bracket adjustments). Always verify kit specs against your vehicle’s GVWR and existing suspension geometry.
Why Choose Air Suspension Over Traditional Coil Springs for a C10?
Air suspension offers on-demand ride height adjustment—critical for towing, hauling, or achieving a lowered stance. Unlike static coils, airbags prevent sagging under load and improve weight distribution. It also future-proofs the truck for engine swaps or custom builds requiring dynamic suspension tuning.
What Maintenance Does a C10 Air Suspension System Require?
Inspect air lines monthly for cracks and fittings for tightness. Drain moisture from tanks seasonally to prevent compressor corrosion. Lubricate bag sleeves with silicone spray annually. Use a leak detection spray biannually on connections. Replace desiccant in air dryers every 15,000 miles to maintain air quality.
Can a C10 Air Suspension Kit Handle Heavy Towing or Racing?
Yes, with dual-path compressors and 1/2-inch air lines, these kits support towing up to 12,000 lbs. For racing, pair with monotube shocks and dual-rate air springs. Brands like Ridetech offer drag-specific kits with reinforced bags rated for 300 PSI and instant pressure adjustment via Bluetooth.
“Modern C10 air suspension kits bridge classic aesthetics with cutting-edge performance. We’re seeing a 40% increase in customers using them for restomods—they want the lowrider look without sacrificing daily drivability. The key is matching the air spring’s cycle life to the vehicle’s usage profile.”

FAQs
- How much does a quality C10 air suspension kit cost?
- Entry-level kits start at $2,500; full-featured digital systems reach $6,000+, including installation hardware and management systems.
- Does air suspension affect C10 alignment settings?
- Yes—always realign after adjusting ride height. Track alignment specs at your most-used pressure setting.
- Can I retrofit air suspension without cutting the frame?
- Bolt-on kits exist, but some trimming of inner fenders or bed supports may be needed for optimal bag placement.
