Restoring or customizing a 1968 Chevrolet C10 often starts with the suspension. The factory setup from that era delivered a comfortable but soft ride with considerable body roll. Upgrading the suspension not only improves handling and safety but also gives your truck the stance you want. Whether you are aiming for a classic stock height, a sporty drop, or an adjustable air ride, choosing the right suspension kit is crucial. This guide covers the main types of suspension kits for the 1968 C10, what to look for in components, and practical advice for your build.

Types of Suspension Kits for 1968 Chevy C10
The aftermarket offers several approaches to upgrading the suspension on a 1968 C10. The best choice depends on your budget, driving style, and desired appearance.
Drop Spindles and Coil Springs
For a simple and budget-friendly lowering, many owners start with a set of drop spindles in the front and lowering coil springs in the rear. Drop spindles lower the front without changing the spring rate, preserving ride quality. Pairing them with 2- to 3-inch drop spindles and matching rear coil springs can lower the truck 4 to 5 inches total. This combination retains the stock control arms and is a straightforward bolt-on upgrade. It works well for daily drivers who want a mild drop without complex fabrication.
Complete Coilover Conversion Kits
A coilover conversion replaces the factory coil spring and shock absorber with a single adjustable coilover unit. These kits typically include new upper and lower control arms, coilovers, sway bars, and all necessary hardware. For the 1968 C10, coilover conversions offer excellent adjustability for ride height and damping. You can fine-tune the stiffness for street cruising or performance driving. The downside is cost and installation complexity. A complete front coilover kit with tubular control arms can cost significantly more than a basic drop spindle setup. However, the handling improvement is dramatic.
Air Ride Suspension Kits
Air ride systems use air bags instead of springs, allowing you to adjust ride height on the fly. Many 1968 C10 owners choose air ride for the ability to lay frame or achieve a perfect daily height. Complete air ride kits include air bags, compressors, tanks, valves, and management systems. Some kits are designed as bolt-on replacements for the stock suspension components. Air ride provides a smooth ride and customizable stance, but it requires more maintenance and periodic checks of the air system. It is also the most expensive option.
Leaf Spring Kits (for the Rear)
If your 1968 C10 has a leaf spring rear suspension (common on many examples), upgrading the leaf springs can improve load capacity and ride quality. Most leaf spring kits are designed to lower the rear by a specific amount, typically 2 to 5 inches. Some kits include new leaf packs, shackles, and hardware. For a leaf spring rear, you can also add a rear sway bar to reduce body roll. If you convert to a four-link or parallel four-link suspension, you will need additional components, but basic leaf spring upgrades are straightforward.
Key Components and What to Look For
When selecting a suspension kit for your 1968 C10, pay attention to these details.
Material and Build Quality
Look for kits with CNC-machined billet aluminum or high-strength steel components. Welds should be clean and consistent. Cheaper kits may use lower-grade steel that can rust or fail. Be especially cautious with control arms and brackets. Powder-coated finishes offer better corrosion resistance than painted ones.
Compatibility and Fitment
The 1968 C10 has specific suspension geometry. A kit advertised for 1967–1972 C10s will likely fit, but double-check that it accounts for differences such as brake caliper clearance. Some kits require trimming or drilling for installation. Read the description carefully. Kits that include all necessary brackets, bolts, and bushings save time and prevent fitment surprises.
Included Hardware and Instructions
A complete kit should include grade 8 bolts, lock washers, nylon locking nuts, and proper bushings. Polyurethane bushings are more durable than rubber but can be stiffer. If you prefer a quieter ride, rubber bushings are acceptable. Good instructions are essential. Some brands provide detailed printed manuals or online videos. Avoid kits with vague or missing instructions.
Installation Considerations
Installing a suspension kit on a 1968 C10 can be a weekend project for an experienced DIY mechanic, but first-timers should expect challenges. Working with old, rusted bolts is common. Penetrating oil, a torch, and impact tools help. For coil spring removal, use a spring compressor. For air ride systems, consider professional installation if you are not comfortable with wiring and plumbing. After installation, a professional alignment is essential to ensure proper tire wear and steering response. Also, check brake lines and hoses for clearance when the suspension is at ride height.
Popular Brands for 1968 C10 Suspension Kits
Several aftermarket brands have established reputations for quality C10 suspension parts. ECE (Early Classic Enterprises) offers drop spindle and coil spring kits specifically for these trucks. Belltech provides a wide range of lowering kits, including drop spindles and shocks. McGaughys is known for high-quality drop spindles and complete springs kits. For coilover conversions, RideTech and QA1 are popular choices. Air ride enthusiasts often choose AirLift or RideTech for complete systems. These brands consistently release parts engineered for the 1968 C10, and their components are widely used in the C10 community.
Final Recommendation
If you are on a tight budget and want a mild drop, choose a drop spindle and coil spring kit from ECE or Belltech. It is simple, effective, and reversible. For improved handling and adjustability, a coilover conversion from RideTech or QA1 is a worthy upgrade, though it costs more. If you want the ultimate stance and versatility, invest in an air ride suspension from AirLift. For most daily drivers, a 4- to 5-inch drop with proper shocks and a front sway bar provides a great balance of looks and drivability. No matter which kit you choose, ensure it includes all necessary hardware and follows the manufacturer's instructions carefully. A well-chosen suspension kit will transform your 1968 Chevy C10 into a truck that handles better and looks exactly the way you want.
