Our cartridge kit for Harley-Davidson baggers, features the same innovative design we developed on the racetrack. This advanced hydraulic system is engineered to absorb every bump in the road, providing riders with exceptional confidence and traction. Drawing from our extensive racing background, we've crafted a suspension that is not overly stiff like a typical race system but is instead finely tuned for optimal performance on the road. Our deep understanding of suspension dynamics allows us to deliver a system that ensures a smooth, controlled ride, enhancing comfort without compromising on responsiveness or stability. Experience the perfect blend of race-proven technology and road-ready comfort with our cutting-edge cartridge kit.

Setting us apart from competitors, Our three-valve system offers significant advantages over a two-valve system due to its enhanced fluid control and pressure management capabilities. The inclusion of a base valve, in addition to the rebound and compression valves, allows for more precise modulation of hydraulic fluid flow. This precision reduces the likelihood of fluid cavitation and pressure spikes, which can lead to inconsistent damping and harsh ride characteristics in two-valve systems. The base valve is particularly beneficial because it allows us to finely tune the compression characteristics: it provides a softer response during low-speed compression strokes, ensuring comfort and smoothness, but ramps up effectively during heavy compression impacts, such as hitting a pothole or a speed bump. This adaptability ensures that the suspension remains stable and responsive across a variety of conditions, offering a smoother, more controlled ride and maintaining better traction by keeping the tires consistently in contact with the road surface.

Furthermore, our kits are tailor-made for each rider. By considering factors like rider weight, bike weight, and riding preferences, we craft a kit that perfectly suits your individual needs.

We've never outsourced any of our machine work or engineering. Everything in your front end is wholly American made in Ventura, CA, and we are proud of this. The end result? More traction, more comfort, and most importantly a ride that really puts a smile on your face. We take every riders weight, and their style of riding into account when we build their kit. We know that setup is key to good suspension, and we take pride into giving every rider a kit that is custom made for them. Whether you want a buttery smooth ride to cruise your bumpy home roads, or you want a ride on rails that can take the abuse of a track day. We have you covered.


Our kit is fully adjustable (preload, compression, and rebound). These adjustments can be found on your new fork cap. Some riders prefer to set it and leave it, while some riders like to tinker between setups. Either way, we are a call away for all your setup questions.


Our kit bumps your stroke from 117mm to 122mm. We work hard on the R&D side when it comes to finding the optimal amount of stroke for every bike.


We also build custom lengths to accommodate those who want more ground clearance, or different geometry. The customer will need to supply the longer chrome tubes in these cases, and we will build it to length. Feel free to give us a call with questions.


Slight modification of your upper tubes required** the larger diameter piston requires more clearance and removal of the oem bottoming assembly is required. Optionally, you can choose to add our ready modified fork tubes to your order. See installation video below:

Note: for 2024 ABS models going 2" over, they will need to purchase extended lower lines. We recommend the Magnum 2" over lines for ABS unit dual disc models. 

Pricing includes a spring set selected by our setup technician based on your riding information
