Does Holley Make Suspension Parts? (What You Need to Know)

If you’re building or upgrading a performance vehicle, you probably know Holley for their carburetors, EFI systems, and fuel pumps. But when it comes to chassis and suspension, the question arises: does Holley make suspension parts? The answer is yes, but with a nuance. Holley, as a parent company, manufactures suspension components through its owned brands—most notably QA1, but also others like Earl’s and Hooker (the latter focusing on exhaust, not suspension). In this article, we’ll break down exactly what suspension parts Holley offers, where they come from, and whether they’re a good choice for your ride.

Understanding Holley’s Product Line

Holley Performance Products has been a cornerstone of the automotive aftermarket since 1903. While their fame rests on fuel and ignition systems, the company has expanded aggressively through acquisitions. Today, Holley owns several performance brands that cover suspension, chassis, and driveline components. The primary brand for suspension is QA1, which Holley acquired in 2017. QA1 is well-regarded for its shocks, coilovers, control arms, and other handling parts. Additionally, Holley sells suspension parts under the Holley brand name itself—most of which are manufactured by QA1 or other Holley-owned subsidiaries. So when you buy a Holley-branded sway bar or coilover kit, you’re essentially getting QA1 engineering and quality.

What Suspension Parts Does Holley Offer?

Holley (through QA1) offers a comprehensive range of suspension components for muscle cars, hot rods, trucks, and late-model performance vehicles. Here’s a breakdown of the main categories:

Coilovers and Shocks

Holley’s most popular suspension offerings are coilover kits and individual shocks. They provide adjustable damping, ride height adjustability, and often come with springs matched to your vehicle’s weight and intended use. For example, the Holley/QA1 Proma Star coilover system is a favorite for street performance and occasional track use. You’ll find single-adjustable and double-adjustable versions, as well as remote-reservoir options for extreme handling.

Control Arms

Holley offers tubular control arms for front and rear suspensions. These are designed to replace heavy factory arms with lightweight, stronger units that improve geometry and reduce unsprung weight. Many come with polyurethane or spherical bushings, depending on your NVH tolerance. Applications cover GM A-body, Fox-body Mustang, and many other popular platforms.

Sway Bars

Holley sells sway bars (anti-roll bars) that are thicker and stiffer than stock. They are typically made from heat-treated alloy steel and include polyurethane bushings. These bars reduce body roll during cornering and can be paired with Holley’s end links and mounting hardware.

Springs

Coil springs for both front and rear are available from Holley. These are branded as Holley/QA1 springs and are designed to work with their shock/strut packages. They offer various spring rates so you can fine-tune ride quality and handling balance.

Mounts and Hardware

To complete the installation, Holley provides shock mounts, spring spacers, control arm brackets, and necessary hardware. They also sell full bolt-in front suspension kits that include control arms, coilovers, sway bar, and all mounting pieces—essentially a one-box solution.

Are Holley Suspension Parts Any Good?

The short answer: yes, they are high-quality components, especially if you consider the QA1 lineage. QA1 has been a trusted name in racing and street performance for decades. Their shocks use chrome-moly steel bodies, Teflon-coated piston rods, and multiple piston designs that deliver consistent damping. However, Holley’s suspension parts are not the cheapest on the market. They sit in the mid-to-upper price range, comparable to brands like Bilstein, Eibach, and Koni. Where Holley excels is in customer support and compatibility—they list specific parts for specific years and models, reducing the guesswork.

One caveat: if you’re after a pure track-day setup, you might prefer more specialized brands like Penske or MCS. But for a street-driven muscle car or a weekend autocrosser, Holley’s suspension parts offer an excellent balance of performance, adjustability, and street manners.

How to Choose the Right Holley Suspension Parts for Your Vehicle

When shopping for Holley suspension, you need to consider your vehicle’s application, your driving style, and your budget. Here are the key factors:

Vehicle Application – Holley lists products by make, model, and year. Use their online catalog to find parts specifically designed for your car. Do not assume cross-compatibility; a Mustang kit won’t fit a Camaro.

Intended Use – Are you daily driving? Drag racing? Road course? Autocross? Holley offers different levels of adjustment. For street use, a single-adjustable coilover with a comfortable spring rate is enough. For track use, consider double-adjustable shocks and stiffer springs. For drag racing, look for the QA1 drag-specific products with lighter weight and launch-focused tuning.

Budget – Holley parts cost more than generic no-name brands but less than top-end race units. Expect to pay $150–$300 per shock/coilover and $200–$500 for a set of control arms. Full front-end kits run $800–$1,500. Weigh these costs against the performance gain.

Ease of Installation – Many Holley suspension parts are designed as bolt-in replacements. If you have basic mechanic skills, you can install coilovers and control arms in a weekend. Some kits require welding or cutting, so check the description carefully.

Where to Buy Holley Suspension Parts

Holley suspension parts are sold through Holley’s own website (Holley.com) and authorized dealers like Summit Racing, Jegs, and specialty performance shops. Local speed shops may also carry them. Buying from an authorized dealer ensures you get the correct part number and warranty support. Some online retailers offer free shipping or package deals on full suspension kits.

Final Recommendation: Should You Buy Holley Suspension Parts?

If you are looking for a one-stop shop for your car’s suspension and you value proven engineering with strong customer support, Holley is a solid choice. The parts are reliable, well-documented, and backed by a major aftermarket company. However, be aware that Holley-branded suspension components are essentially QA1 parts with different branding. You can often find the same QA1 parts for slightly less money by going directly to QA1’s website or other QA1 dealers. That said, Holley’s bundle deals (e.g., a complete front suspension kit) can simplify your build and save you from sourcing separate components.

For pure racers or budget-restricted builders, other brands may offer more specialized or cheaper alternatives. But for the enthusiast who wants a dependable, well-engineered suspension upgrade without hassle, Holley delivers. Take your time to verify fitment for your specific year and model, and you’ll be happy with the results.
