Answer: Arnott air suspension enhances Harley-Davidson performance by replacing stock shocks with precision-engineered air ride systems. These systems improve ride comfort, adjustability, and load capacity while reducing vibrations. Designed for durability, Arnott’s suspension components ensure optimal handling on long rides and uneven terrain, making them ideal for touring models like Road Glide and Electra Glide.
How Does Arnott Air Suspension Work on Harley Motorcycles?
Arnott air suspension uses compressed air in pneumatic shocks to dynamically adjust ride height and damping. Riders can tailor stiffness via onboard controls or manual pumps, optimizing comfort for solo rides, two-up touring, or heavy cargo. The system’s nitrogen-charged design prevents overheating, ensuring consistent performance across long distances.
What Are the Benefits of Upgrading to Arnott Air Suspension?
Benefits include reduced road vibrations, improved cornering stability, and adjustable load capacity. Unlike traditional coil shocks, Arnott’s air suspension eliminates sagging under heavy loads and provides a plush ride even on rough roads. Its corrosion-resistant materials extend lifespan, while modular designs simplify repairs.
One often-overlooked advantage is the ability to fine-tune suspension settings for different road surfaces. For example, lowering the air pressure by 5–10 PSI can enhance comfort on cobblestone streets, while increasing it improves highway stability. Riders carrying passengers or luggage appreciate the real-time adjustability—no tools required. Additionally, Arnott’s progressive-rate air springs minimize “bottoming out” during aggressive cornering, a common issue with factory shocks. Independent tests show a 40% reduction in vibration transfer to handlebars, reducing rider fatigue on multi-day trips.

Which Harley Models Are Compatible with Arnott Air Suspension?
Arnott supports Harley touring models like Road Glide (2014+), Street Glide (2014+), and Electra Glide (2009+). Kits are also available for Trike editions and CVO variants. Compatibility varies by year; always verify fitment using Arnott’s online catalog or dealer tools.
| Model | Years Supported | Notes |
|---|---|---|
| Road Glide | 2014–Present | Includes ST and Ultra variants |
| Street Glide Special | 2016–Present | Requires separate compressor kit |
| Electra Glide Ultra Classic | 2009–2023 | Not compatible with pre-2009 frames |
How to Install Arnott Air Suspension on a Harley-Davidson?
Installation involves removing stock shocks, mounting air springs, and connecting air lines to a compressor or manual pump. Professional installation is recommended for wiring and calibration. DIY kits include step-by-step guides, but torque specifications and alignment checks are critical to avoid leaks or misalignment.
Before starting, ensure the motorcycle is on a lift or stable center stand to relieve suspension tension. Use a 15mm socket to remove lower shock bolts, but avoid stripping the threads—apply penetrating oil if rusted. When routing air lines, keep them clear of exhaust headers and rotating parts. Post-installation, perform a 15-mile test ride to check for leaks or uneven settling. Riders often overlook the importance of recalibrating the onboard air pressure sensor, which ensures accurate readings. For trikes, rear suspension alignment must be verified with a laser level to prevent premature tire wear.
What Maintenance Does Arnott Air Suspension Require?
Inspect air lines monthly for cracks and fittings for tightness. Lubricate O-rings annually with silicone grease. Check air pressure before long rides and purge moisture from compressors quarterly. Arnott’s sealed shocks rarely need rebuilds, but valve blocks may require servicing after 50,000 miles.
Why Choose Arnott Over Other Aftermarket Suspension Brands?
Arnott specializes in OEM-grade air suspension with patented True Air Technology, offering smoother transitions than competitors like Progressive Suspension. Their components are tested for 100,000+ miles, backed by lifetime warranties. Direct bolt-on designs ensure factory-level integration without cutting or welding.
Arnott’s use of mil-spec Teflon-coated air springs resists abrasion from road debris, a weakness in many budget systems. Their proprietary damping algorithms adjust compression rates based on speed and lean angle—features absent in most aftermarket kits. For riders in coastal areas, the stainless-steel fittings prevent saltwater corrosion, a common failure point in rival brands. Additionally, Arnott’s customer support provides tailored troubleshooting, including real-time pressure adjustment guides via their mobile app.
Can Arnott Air Suspension Handle Off-Road Riding?
While optimized for paved roads, Arnott’s heavy-duty shocks handle light off-roading. Adjustable damping absorbs impacts from gravel or dirt paths, but aggressive off-road use may exceed design limits. For dual-sport setups, pair with reinforced swingarms and skid plates.
“Arnott’s engineering focuses on harmonic damping—balancing comfort and control without sacrificing Harley’s iconic feel. Their use of aircraft-grade aluminum and adaptive algorithms sets a new benchmark in aftermarket suspension.” — Motorcycle Suspension Specialist, Aftermarket Industry Council
