Arnott MC-3105 Suspension Kit - Rear

Arnott Smooth Ride Air Suspension Kit

The Arnott Smooth Ride Series adjustable motorcycle air suspension kit MC-3105 is built for 1991-2007 Harley-Davidson Dyna models. It adds on-the-fly rear ride-height adjustment through an onboard compressor and toggle switch, giving riders a lower stance when parked and a more controlled setup on the road.

• Adjustable rear suspension with onboard compressor and switch
• Over 3 inches of travel for ride-height tuning
• Two 13-inch nitrogen-charged mono-tube shocks with Internal Floating Piston (IFP)
• Goodyear air spring for height adjustment based on rider weight and road conditions
• Small compressor, mounting bracket, and air distribution valve block with muffler
• Custom-crafted and tested in Arnott’s Florida manufacturing facility

Product Line Details

Arnott’s Smooth Ride Series focuses on adjustable motorcycle suspension that balances comfort, control, and stance. For Harley-Davidson Dyna owners, this line provides a practical way to lower the bike at rest, raise it for riding, and fine-tune rear suspension response without changing the overall character of the motorcycle.

Detailed Description

Part number MC-3105 uses custom-valved mono-tube shocks with an Internal Floating Piston to help separate gas from oil, reducing foaming and cavitation for more consistent damping. The air spring setup lets riders tailor rear suspension height to body weight, passenger load, road surface, and riding preference. This makes MC-3105 a strong option for Harley-Davidson Dyna riders looking for a lower parked stance, easier footing at stops, and adjustable rear suspension performance on the street.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Solve

• Difficulty flat-footing the motorcycle at stops
• Rear ride height that does not match rider weight or load
• Harsh or inconsistent rear shock response
• Limited clearance control when parking or maneuvering
• Need for a lower stance without giving up adjustable suspension

Installation Notes and Tips

MC-3105 is a direct-fit suspension kit for 1991-2007 Harley-Davidson Dyna applications. Review the included user manual before installation, route the wiring harness carefully, and verify air line connections and compressor mounting before final setup. After installation, cycle the suspension and confirm proper ride-height adjustment with the toggle switch.

Quality Assurance

Each shock is custom-crafted and rigorously tested in Arnott’s Florida manufacturing facility. Arnott backs the MC-3105 with a Limited Lifetime Warranty.
