AK-20 Axxion Cartridge Kit for Harley-Davidson Motorcycles

We recommend only EXTREMELY competent mechanics attempt this installation. It is not a job for a Do-It-Yourselfer. If you don't have acces to a qualified mechanic and don't feel comfortable installing the kit yourself, just send your forks in and we will install it for you for a reasonable fee. Our typical turn around is less than one business week, so you wont be off the road for long!

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 the guts in your stock ill-performing forks.  They will elimanate the bottoming, clanging, diving and bouncing you have sadly been forced to get used to.  The result is dramatically improved comfort, confidence, and control.

Included in the kit is one pair of the world's finest fork cartridges, one set of our proprietary Omni Fork Springs matched to your weight and riding preferences, a nice set of stainless steel fork caps with external damping adjusters, high quality fork fluid, and step by step instructions on installing the kit.

All Traxxion Dynamics Products carry the prestigious "Certified Made in USA" brand, having passed an intensive audit process.

For the techies who want to know the "Specs", the 20mm cartridge tubes in the AK-20 Kit are bored and honed to +/-.0005". The 12.5mm cartridge rods are centerless ground to +/-.0005". No other suspension unit is held to these exacting standards. Our 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 these features lead to a cartridge that performs beyond any customer's expectation. As an added bonus, the kit is completely modular in construction, and can be retrofitted to future bikes you may buy.

A few special tools are needed to install the kit and we have prepared an inexpensive package that has everything a qualified mechanic will need to install your AK-20 Axxion Cartridge Kit and service your forks when needed in the future.

Big Improvement over Gold Valve Emulators
Submitted by Caleb on
Got a local bike shop to fit the kit. the ride is slightly more accommodating but handling is far more secure on a bumpy corner. With Michelin Commander 2 tyres the bike tracks perfectly up to max speed. The original set up was terrible. Bottoming out all the time but still handled like a sack full of custard. the kit isnt cheap but well worth the investment. Traxion Dynamics were very helpful over the phone too.
