Ridetech 63-72 Chevy C10 Front CoilOver System HQ Series - 11333510

The Ridetech HQ Series Front Coilover System (Part #11333510) is a purpose-built front coilover kit engineered specifically for 1963–1972 Chevy C10 and GMC C15/C1500 trucks. Designed for use with Ridetech's lower StrongArm control arms, this system replaces the factory front suspension with a modern monotube coilover setup that delivers a noticeable improvement in ride quality, handling composure, and ride height adjustability — all in a package that installs without cutting or major fabrication. If you're building a clean street truck, pro-touring C10, or a daily-driven classic that needs to handle as good as it looks, this is the front suspension upgrade to start with.

Key Features & Benefits

• Monotube Gas Pressure Design: Unlike twin-tube shocks, the monotube construction delivers consistent, fade-free damping performance — meaning your suspension behaves predictably whether you're cruising on the highway or pushing through corners.
• Impact-Forged Aluminum Body: The aluminum shock body provides superior strength while keeping weight down — a meaningful upgrade over heavier steel-bodied alternatives common on factory replacements.
• Larger 1.834" Piston: A bigger piston area translates directly to more controlled, refined ride quality. This is one of the design details that separates the HQ Series from more basic coilover options.
• Rebound Adjustable Shocks: Dial in the damping to match your driving style and load conditions. Whether you prefer a softer street cruise or a firmer, more planted feel, you can tune it without swapping components.
• Unique Pinch Clamp Height Adjuster: Ridetech's finer-thread pinch clamp design makes ride height adjustment easier and more precise compared to traditional coarse-thread adjusters — useful when you're dialing in your stance.
• CNC Machined Billet Hardware & Anodized Finish: Every machined component is CNC-produced for tight tolerances, and the anodized finish protects against corrosion — important for a truck that might see year-round driving or humid climates.
• Kevlar-Lined Bearings: The 1/2" bore x 1" kevlar-lined bearings at both the top and bottom mounting points allow for noise-free operation and long service life without the squeaks and clunks associated with worn rubber bushings.
• HyperCo Coil Springs (Made in Indiana): Ridetech sources their 2-1/2" coilover springs from HyperCo, using high-tensile premium steel, CNC cold-wound for reduced weight, improved resistance to bowing, and increased travel — finished with a durable powder coat.
• Double-Sealed Rod Guide with Dust Cover: Keeps contaminants out and oil in — extending the service life of the shock and maintaining consistent performance over time.
• 5/8" Chrome Shock Shaft: A larger-diameter chrome shaft resists bending and wear under load, adding to the durability of the overall assembly.
• Sold as a Complete Pair: Both left and right coilovers are included, along with springs, spring mounts, and delrin spring washers — everything you need for a front suspension upgrade in a single purchase.

Frequently Asked Questions

Q: Do I need any other parts to install this coilover system on my C10?
A: Yes — this system is specifically designed for use with Ridetech's lower StrongArm control arms. It is not compatible with the factory stock lower arms. If you don't already have Ridetech StrongArms installed, you'll need to add the appropriate front StrongArm system for your year (1963–1970 or 1971–1972) before or alongside this coilover kit.

Q: Does this kit fit both the Chevy C10 and GMC trucks?
A: Yes. In addition to the 1963–1972 Chevy C10 Pickup, this kit also fits a range of GMC trucks including the GMC 1000 Series, 1500 Series, C15/C1500 Pickup and Suburban, and more. See the full fitment table above for specific year ranges by model.

Q: Is this a single-adjustable or double-adjustable coilover?
A: This is a single-adjustable system — the shocks feature rebound adjustment. Ridetech also provides a Shock Tuning Guide (downloadable from their site) to help you dial in the right settings for your application.

Q: What's included in the kit — do I need to source springs separately?
A: Coil springs are included. The kit ships as a pair and contains the coilover shocks, Ridetech/HyperCo coil springs, spring mounts, and delrin spring washers. You should not need to source springs separately.
