Highlights

  • PSR (Position Sensitive Rebound), a new unique hydraulic top-out system that eliminates harsh top out and improves sensitivity.
  • Riders can now adjust high and low speed compression with a common multi-tool, needing only 5 mm and 4 mm Allen keys.
  • Frequency dependent damping Adjustable HBC: Once Developed by EXT for motorsport and later introduced in MTB applications, the new HBC system is now more powerful and starts in the last 20% of the stroke. This allows for a lower spring rate choice for maximum compliance, traction, and control.
  • No risk of cavitation: high turbulent flow valves keep damping forces independent from viscosity and temperature changes to perfect pressure balance, eliminate aeration and cavitation, all with very low hysteresis to improve dynamic response.
  • New coatings: improved durability thanks to a new proprietary DLC coating of the chrome-moly steel shaft, and an innovative proprietary DHC tube coating process, both assuring maximum wear resistance.
  • Spring thrust bearings ensure alignment, prevent spring rub and minimize spring noise.

Description

The Arma V4 is specifically designed to raise the bar on what is possible in MTB damper performance technology. Don’t be fooled by the similar appearance to its V3 predecessor, for beneath the surface the V4 refines and improves what was already an industry game changer. Building off of our prestigious pedigree in motorsports racing, EXT has worked diligently to put out a damper that ensures its rightful place as innovative industry leaders in the highly competitive MTB marketplace.

Arma V4 is designed for aggressive riders. Ideal for DH and E-bike applications where LOK pedal efficiency is not necessary. In exchange of the LOK 2.0 option found on the Storia V4, Arma has a more aggressive HBC allowing the shock to be more supportive at the end of it's stroke.
