EXT Racing Shox Arma V4 Rear Shock, 230 x 65mm Stroke, Standard Eyelet

The new EXT Arma and Storia V4 Series—now available in our store! These shocks take the proven performance of the V3 and elevate it to new heights with innovative features designed for even better damping performance and control.

While the V4 may look similar to its predecessor, it’s packed with significant upgrades under the hood. It retains key elements like the mid-body damper, hydraulic bottom-out circuit, and exceptional high-speed control, while incorporating rider feedback to refine performance even further. New additions include a position-sensitive rebound system, frequency-dependent damping, an externally adjustable HBC (Hydraulic Bottom-Out Control), and a steel DLC-coated damper shaft for enhanced durability and reduced friction.

The result? A stronger, quieter shock that delivers smoother performance and more precise tuning options for serious riders looking to push their limits. Stop by to learn more or check out the V4 Series for yourself!
