American Suspension RAMAIR CARTRIDGE KIT FOR FRONT AIR RIDE

Big-Wheel Control. Air Ride Comfort. Real Handling.

The RamAir™ Cartridge Kit is the first and only high-performance front fork valving cartridge engineered specifically to work with front air ride systems on Harley-Davidson Touring motorcycles.

Fits 2014–2026 Harley-Davidson Touring models with 49mm front forks.

Most front air ride setups change ride height — but do nothing to control suspension motion. The result is a harsh ride, vague steering, and unstable handling, especially on big-wheel baggers.

The RamAir Cartridge Kit fixes that at the source.

Designed from the ground up to function with air ride, not adapted to it, this cartridge transforms how your bike handles, tracks, and feels on real roads.

A Must-Have Upgrade for Any Big Wheel Install

Oversized front wheels dramatically increase weight and leverage on the front suspension. Proper valving is critical.

The RamAir™ Cartridge Kit is engineered to control the additional mass and forces created by big wheels. Whether you are running front air ride or a stock spring fork setup, this cartridge is foundational for ride quality, stability, and safe handling.

This upgrade is not optional for big wheel builds.

Why Front Air Ride Needs a Different Cartridge

Stock fork internals and conventional cartridges were never designed for:

• Heavy Harley-Davidson Touring motorcycles

• Oversized and wide front wheels

• Front air ride suspension systems

Without proper damping control, air-ride bikes suffer from:

• Harsh ride quality

• Poor front-end feedback

• Unstable cornering

• Front-end deflection and chatter

The RamAir Cartridge Kit was engineered specifically to solve these problems.

No other valving cartridge on the market works with AIR RIDE.
We were first. We are the only.
Patent Pending.

Engineered for Big-Wheel Baggers

Unlike traditional fork cartridges, the RamAir Cartridge Kit features:

• Oversized damping piston (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

This design delivers predictable damping and controlled movement — even on heavy touring bikes running large front wheels.

“It takes a bike you hated to ride and turns it into something that sticks to the road like stepped-on gum.”

Real-World Ride & Handling Benefits

• Dramatically improved ride quality

• Predictable, confidence-inspiring handling

• Reduced harshness and front-end deflection

• Stable steering with oversized front wheels

• Makes big-wheel baggers enjoyable to ride — not just look at

This upgrade is about control, not cosmetics.
