American Suspension RAMAIR™ Cartridge Kit for Front Air Ride
Big-Wheel Control. Air Ride Comfort. Real Handling.
The American Suspension RamAir™ Cartridge Kit is a high-performance front fork valving cartridge engineered specifically to work with front air ride systems on Harley-Davidson Touring motorcycles.
Most front air ride setups change ride height but do not control suspension motion. The RamAir Cartridge Kit addresses harsh ride quality, vague steering, unstable handling, front-end deflection and chatter by adding damping control designed specifically for air-ride and big-wheel applications.
A Must-Have Upgrade for Big-Wheel Builds
Oversized front wheels add weight and leverage to the front suspension. The RamAir Cartridge Kit is engineered to control the additional mass and forces created by big wheels. It can be used with front air ride or a stock spring fork setup.
Engineered for Big-Wheel Baggers
- Oversized damping piston with 2–3× the surface area of typical cartridges
- Negative spring technology for improved small-bump compliance
- Flow-through damping system for smooth, consistent control
- Adjustable ride height to maintain proper geometry across wheel sizes
Ride & Handling Benefits
- Dramatically improved ride quality
- Predictable, confidence-inspiring handling
- Reduced harshness and front-end deflection
- Stable steering with oversized front wheels
- Improved control on heavy Touring motorcycles and big-wheel baggers
Wheel-Specific Valving — Built for Your Setup
