AK-20 Axxion Cartridge Kit for Harley-Davidson Motorcycles

Traxxion Dynamics is proud to introduce the next revolution in motorcycle suspension; The AK-20 Axxion Cartridge Kit!

The AK-20 Axxion Cartridge Kit is a complete bolt-in upgrade that replaces Harley's stock ill-performing Japanese-made springs and damping rods, with a pair of USA-designed and manufactured, extremely high-tolerance CNC-machined cartridges, and top quality springs to your needs, weight, and intended use.

Traxxion's 20mm cartridge tubes are bored and honed to .0005". The 12.5mm cartridge rods are centerless ground to .0005", as well. No other suspension unit is held to these exacting standards. Their unique bearing design helps seal the cartridge to improve low speed damping and increase damping response time, and virtually eliminates stiction. The components are then hard-coat anodized to prevent oxidation and wear contamination of the fork fluid. All of this leads to a cartridge that performs beyond any customer's expectation; this is such a remarkable improvement in the comfort, control and confidence you'll have on your bike, you won't recognize it as your own!

As an added bonus, the kit is completely modular in construction, and can be retrofitted to future bikes you may buy. Included in the kit is one set of AK-20 Axxion Cartridges, one set of our proprietary Omni Springs matched to the rider's weight and riding preferences, two quarts of racing quality fork fluid, and step by step instructions on installing the kit; we recommend professional installation at our facility. A few specialized tools are needed to install the kit and we have prepared an inexpensive package that has everything you need to install your AK-20 Axxion Cartridge Kit and service your forks when needed - please contact Rocket Moto customer service for information.

If you are not comfortable installing the kit yourself, just send your forks in to us, and we will service the forks and install the AK-20's for you. Our typical turn-around is about one business week, so you won't be off the road for long!

Your Harley's stock forks don't include external rebound damping adjustment. This kit includes beautifully machined upgraded fork caps, allowing you to tailor the ride and handling of the suspension with just a small turn of a knob.
