Put some American GUTS into those wimpy Japanese forks on your Harley! (No, they aren’t made in America…) You don’t weigh 120 pounds, and that front suspension on your bike can’t hold you up! If you are tired of the bouncing, wallowing, bottoming, chattering, wobbling of your stock forks, then TRAXXION DYNAMICS has the CURE!

See what our customers have to say!

“What’s wrong with my stock forks?” you ask…Your stock Showa forks have a “damper rod” in them to control the movement of the wheel. This style of fork is used for cheap production parts. Trying to compare a damper rod fork to a cartridge fork is like trying to compare a carburetor to fuel injection. There simply is no comparison. The damper rod fork is the cheapest, poorest performing system of damping, and has been around on Harleys for so long nobody seems to be able to remember.

The next problem is your stock fork springs. The stock springs are so weak and wimpy that they can’t even hold the bike up; never mind that they are completely unable to hold you up when you get on it, or you take a passenger along. Just pick your bike up off the side stand sometime and watch it collapse before you even get on!

The result is a fork that bottoms over large bumps, wallows in high speed turns, dives dramatically when you pull the brake, cups and tears up your tires, and leaves you generally feeling uncomfortable and lacking confidence in the feel of your bike.

The “cartridge fork” came along about 20 years ago in sport bikes, and since has been highly refined. The kit you see in these photos is absolutely STATE OF THE ART. It was introduced in February of 2005. It is EXTERNALLY ADJUSTABLE to suit your personal preferences. It comes with springs matched to your weight and your intended use and best of all, IT WORKS!



The AK-20 Axxion Cartridge Kit DRAMATICALLY transforms ill handling Harleys with Showa forks (basically any bike since about 1988). Immediately you will feel a smooth, controlled ride. The bike will not dive under aggressive or panic braking. You will have a confident feel even in high speed sweeping turns. Your tire wear will improve dramatically. Your pegs and floorboards will stop dragging the ground in turns. You will have great control and stability at low speeds, such as moving through a parking lot. Even your passenger will notice the difference! Overall, you won’t recognize your own bike!!!

This kit is Made In The USA with pride in Woodstock, Georgia by skilled machinists and craftsmen. You cannot buy a better working set of forks anywhere, at any price. We guarantee it. Most AK-20 Kits for Harley-Davidson Motorcycles are $1249.95. Some models like the Street Rod and XR1200 are slightly more ($1499.95) due to the fork caps required.


If you are looking for a little more budget conscious solutions we do offer a Damper Rod Upgrade. This is by no means close to the results you will achieve with the AK-20 Axxion Cartridge Kit but it will make your bike safer and more enjoyable to ride.

AR-25 Upgrade

The AR-25 Axxion Rod kit blends the old style damper rod with the cutting edge technology of today’s cartridge valves. We have integrated our 25mm Axxion Valve used in every level of racing into our damper rod. Our damper rod is designed to seal better and flow oil better than any modified OEM damper rod. The damper rods are machined to our strict tolerances in house on our CNC lathes.

The end result is as close as you can get to installing a cartridge in your fork but still easy on the wallet. Superior bump adsorption, greater traction and front end control.

The kit is a direct bolt-in, requires no drilling, brazing, deburring or other machining. It can be installed quickly and easily by anyone who likes to service their own forks. Just remove the fork cap, dump out the spring and oil, remove the bottom bolt and let the stock rod fall out. Put the all new AR-25 Axxion Rod in, fill with oil, and install the springs and precut spacers and you are ready for the twisties or your next track day for less than half the cost of a cartridge kit!

AR-25 Axxion Rod Kits start at $499.95 and come complete with damper rods, valving, springs, spacers and oil.
