Custom Axis ATV / MX or X-Country

Custom Axis, a division of Penske Racing Shocks, is proud to offer the best available suspension systems for your bike, quad, and snowmobile. Designed with tune ability, performance, and reliability in mind, our off-road line of shocks will give you the best handling for your vehicle. Built to order specifically for your weight and riding style, our shocks are truly custom shocks.

We offer many internal options and upgrades that allow us to tune for plush corning feel, while maintaining high damping levels that eliminate bottoming over large bumps or jumps.

Custom spring set-ups are also available, ranging from single, dual, or triple rate packages. 

Custom Axis also offers our patented AirShock option. This options eliminates your conventional steel or Ti springs. The AirShock has an external and internal body that seal to produce an air chamber. Externally accessible inflation ports allows you to pressurize this chamber to create an air spring. Taking it one step farther, our engineers have designed a two chamber system that allows you to independently control Ride Height and Max displacement spring force. A combination of chambers, cross over rings, and pressure makes spring curve options limitless. There is nothing like riding on air!

We offer the best customer support. Our technicians are not only the ones building the shocks, they also are our at track reps who also ride themselves. We have local test riders who are continually developing with us to ensure we are offering the best possible set-ups.
