Arnotts Air Suspension Shock Part AS2700: A Complete Guide

The Arnotts air suspension shock part AS2700 is a popular replacement for many late-model vehicles equipped with factory air ride systems. Whether you're dealing with a leaking shock, a failing compressor, or just want to restore your vehicle's ride quality, the AS2700 is a direct-fit option designed to meet or exceed OEM specifications. This article covers everything you need to know about this part, including its compatibility, construction, installation insights, and how it stacks up against other options on the market.

What Is the Arnotts AS2700 Air Suspension Shock?

The AS2700 is a complete air shock assembly manufactured by Arnotts, a company that specializes in air suspension components. Unlike a traditional coil-over shock, an air shock uses compressed air to support the vehicle's weight and provide damping. The AS2700 includes the shock absorber, air spring (bellows), and often the solenoid valve and mounting hardware pre-assembled. It's designed as a direct OEM replacement, meaning you can bolt it in without modifications.

Key Features of the AS2700

• Pre-assembled unit: Ready to install out of the box, reducing labor time.
• Corrosion-resistant materials: Uses stainless steel or coated components to withstand road salt and moisture.
• Reinforced bellows: Multi-ply rubber construction for durability and resistance to punctures.
• Integrated solenoid valve: Controls air flow for proper ride height and leveling.
• OEM-level ride quality: Matches the damping and spring rate of the original equipment.

Vehicle Fitment

The AS2700 is commonly used on:

• Lincoln Town Car (2003–2011)
• Lincoln Navigator (2003–2006)
• Ford Expedition (2003–2006)
• Mercury Grand Marquis (2003–2011)

Always double-check your vehicle's make, model, and year before ordering. Arnotts also provides a fitment guide on their website. Some vehicles may require additional parts like a new compressor or height sensors if they are worn.

AS2700 vs. OEM Replacement: Which Should You Choose?

OEM air shocks from the dealer often carry a high price tag. Aftermarket options like the AS2700 offer a cost-effective alternative without sacrificing quality. Here are the main differences:

Price

• OEM: Typically $400–$600 per shock.
• Arnotts AS2700: Usually $200–$350 per shock, depending on the retailer.

Quality

• OEM parts are built to exact factory specs but may use the same materials as the originals that failed.
• Arnotts uses upgraded materials like multi-ply bellows and corrosion-resistant coatings, which can extend service life.

Warranty

• OEM parts often come with a 12-month warranty.
• Arnotts offers a limited lifetime warranty on the AS2700 (check current terms), which provides peace of mind.

Installation

Both are direct fit. The AS2700 includes all necessary hardware, so no extra shopping is needed.

Installation Tips for the AS2700

Installing an air shock requires some mechanical skill. If you're not comfortable working with suspension and air lines, have a professional do it. Here are practical tips for a DIY install:

1. Safety first: Jack up the vehicle securely on jack stands. Never rely on a bottle jack alone.
2. Release air pressure: Before disconnecting the air line, relieve system pressure by cycling the suspension or using the vehicle's service procedure.
3. Remove the old shock: Unbolt the lower mount, disconnect the air line and electrical connector (if solenoid), then remove the upper bolts.
4. Install the new AS2700: Mount the shock in place, tighten bolts to torque specs from the service manual, reconnect the air line and wiring.
5. Bleed the system: Follow Arnotts' procedure to purge air and fill the bellows. Usually this involves cycling the ignition and letting the compressor run.
6. Test ride height: After installation, check that the vehicle levels correctly. If not, you may need to reset the height sensors.

Torque specs (approximate): Lower mounting bolt: 50–60 ft-lb; upper bolts: 20–25 ft-lb. Always use the manufacturer's specifications for your specific vehicle.

Common Questions About the AS2700

Will the AS2700 work with aftermarket compressors?

Yes. The AS2700 uses a standard air fitting and solenoid connector compatible with most OEM and aftermarket compressors. However, if your compressor is old or failing, replace it at the same time to avoid future issues.

How long does the AS2700 last?

Many users report 50,000 to 80,000 miles of service life. Factors like road conditions, climate, and maintenance affect longevity.

Can I convert to coil springs instead?

Conversion kits are available, but the AS2700 is designed for those who want to keep air suspension for ride comfort and load leveling. If you prefer a simpler system, coil conversion might be better.

Practical Recommendation

If your vehicle's air suspension is failing, the Arnotts AS2700 is a solid choice. It offers OEM-level ride quality at a lower price, with an excellent warranty. For most drivers, replacing all four shocks with AS2700 units (if applicable) will restore the original smooth ride. However, if your vehicle is older with high mileage, consider replacing the compressor and height sensors simultaneously. Always purchase from a reputable dealer to ensure authenticity and warranty coverage. For those who are handy with tools, DIY installation is feasible, but professional installation is recommended if you are not experienced with air suspension systems. The AS2700 provides a reliable, cost-effective solution that keeps your vehicle riding as intended.
