The Complete Guide to Aston Martin Suspension Parts

Owning an Aston Martin means enjoying a blend of luxury, performance, and engineering excellence. The suspension system is critical to that experience, delivering both comfort and handling precision. Whether you need to replace worn components or upgrade for better performance, understanding Aston Martin suspension parts is essential. This guide covers the key components, common issues, and what to look for when buying parts for your Aston.

Key Suspension Components in an Aston Martin

Aston Martin suspensions vary by model and generation, but most share core components. Knowing what each part does helps you make informed decisions.

Control Arms and Bushings

Control arms connect the wheel hub to the chassis and allow controlled vertical movement. They are typically made of aluminum for weight savings. The bushings, often rubber or polyurethane, absorb vibration and noise. Over time, bushings crack and cause clunking noises or vague steering. Replacing them restores precision.

Shock Absorbers and Struts

Shocks control spring oscillation and maintain tire contact. Aston Martins use adaptive dampers on many models (like the Vantage and DB11) that adjust firmness electronically. Standard shocks are also common on older models. If you notice excessive bouncing, nose diving, or leaking fluid, it's time for replacement.

Springs and Coilovers

Springs support the vehicle’s weight and determine ride height. Aston uses coil springs on most models, with some having air suspension (e.g., DB9 and Rapide). Lowering springs can improve looks and reduce body roll, but may compromise ride comfort. Coilover kits combine spring and shock into one unit for easy adjustment.

Sway Bars (Anti-Roll Bars)

Sway bars reduce body lean during cornering by connecting left and right suspension. A thicker bar reduces roll but can make the ride stiffer. Upgrading to an adjustable sway bar allows fine-tuning for track or street use.

Tie Rods and Ball Joints

Tie rods link the steering rack to the wheels; ball joints allow the control arms to pivot. Worn parts cause steering play and uneven tire wear. They should be inspected during alignment or suspension work.

OEM vs Aftermarket Suspension Parts

When buying Aston Martin suspension parts, you have two main choices: original equipment manufacturer (OEM) from Aston Martin or aftermarket options.

OEM Parts

OEM parts are made to the same specifications as the factory parts. They guarantee fitment and performance consistent with the car’s original design. However, they can be expensive and may not offer improvements. For daily drivers who prioritize originality and reliability, OEM is a safe choice.

Aftermarket Parts

Aftermarket parts come from third-party manufacturers like KW, Bilstein, Eibach, and H&R. They often offer performance gains such as lighter weight, adjustable damping, or lower ride height. For enthusiasts seeking better handling or a lower stance, aftermarket is appealing. However, quality varies—stick with reputable brands.

What to Consider

• Budget: Aftermarket can be cheaper or more expensive depending on brand.
• Performance goals: If you track your car, upgrade shocks and springs. For street use, OEM-quality parts are sufficient.
• Model specifics: Some Aston Martins have unique suspension setups (e.g., adaptive damping on V8 Vantage). Ensure the parts are compatible with your car’s electronics.

Common Suspension Issues in Aston Martins

Knowing what often fails helps you plan maintenance and avoid surprises.

• Bushing Wear: Rubber bushings in control arms and sway bars crack after 50,000–70,000 miles. Symptoms: clunking over bumps, wandering steering.
• Adaptive Damper Failure: On cars with adaptive damping (e.g., 2000s V12 Vanquish), the electronic dampers can leak or lose calibration. Replacement is costly, so some owners switch to standard coilovers.
• Spring Sag: Over time, springs settle, lowering the car unevenly. This affects alignment and ride quality. Replace in pairs.
• Tie Rod End Wear: Common on higher-mileage cars. Causes loose steering and vibrations.
• Air Suspension Leaks: On models with air suspension (DB9 Volante, Rapide), air struts can develop leaks. Check for compressor cycling frequently or uneven ride height.

How to Choose the Right Suspension Parts

Follow these steps to select the best parts for your Aston.

Identify Your Exact Model and Year

Aston Martin parts vary between model years and trims. For example, a 2006 DB9 uses different control arms than a 2012 DB9. Use your VIN or consult a parts catalog to confirm compatibility.

Set Your Goals

• Restoration: Stick with OEM for originality.
• Regular driving: Quality aftermarket bushings and shocks offer long life.
• Performance driving: Upgrade to coilovers, stiffer sway bars, and polyurethane bushings.

Choose Reputable Brands

For aftermarket, look at:

• Shocks/Coilovers: KW, Bilstein, Ohlins, Nitron.
• Springs: Eibach, H&R, Swift.
• Bushings: Powerflex, SuperPro.
• Control Arms: OEM or reputable brands like Meyle.

Check Reviews and Forums

Aston Martin owner forums (e.g., AstonMartins.com) have real-world feedback on parts. Look for threads about your model to see what others recommend.

Installation: DIY or Professional?

Suspension work requires specialized tools and knowledge of geometry. Simple sway bar or bushing replacement can be done by experienced DIYers if you have a lift and torque wrench. However, tasks involving coil springs (dangerous without a spring compressor) or adaptive damping should be done by a shop. A professional alignment is mandatory after any suspension change.

Final Recommendations

For most Aston Martin owners, replacing worn bushings and shocks with OEM-quality parts will restore the factory ride and handling. If you want a sportier feel, consider a mild upgrade like Eibach Pro-Kit lowering springs paired with Bilstein B6 shocks. For track use, KW Variant 3 coilovers offer excellent adjustability. Always match front and rear components to maintain balance.

Before buying, double-check compatibility with your specific model and consider the cost of installation. A well-maintained suspension will keep your Aston driving like the dream car it is for many more miles.
