Custom Axis ATV / MX or X-Country


Penske Racing Shocks and Custom Axis are proud to offer the best available suspension systems for your bike or quad. Designed with tune ability, performance, and reliability in mind, our off-road line of shocks will give you the best handling bike. 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 jumps.

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

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 also have 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.

*Available for most popular Quad models*

*Front ATV shocks are sold in pairs and are piggy-back or remote canister*
