ARMA V4

The V4 not only retains and refines foundational aspects of the V3, such as its unique mid body damper characteristics, hydraulic bottom-out circuit and notable high speed control, while simultaneously addressing and integrating feedback from our riders. The V4 celebrates a position sensitive rebound hydraulic top out system, frequency dependent damping, an externally adjustable HBC and a steel DLC coated damper shaft. All of this and more coming in a stronger yet quieter package

hydraulic bottom out

First developed for WRC project by EXT, HBC system is a position sensitive damper valve composed by a secondary piston assembled below the main one and an inner tube on the bottom of the damper. When you get close to the end of the stroke, the secondary piston engages the inner tube, so the oil must flow through a calibrated orifice that characterizes the end stroke ramp.

Consistency through the run

• Very high viscosity index and ratio for stability through different temperature changes and stress
• 0.80 g/cc density to provide smoothness and lubricity
• Reduced foam formation and air entrainment
• Complete compatibility with rubber seals

ULTRA-LOW FRICTION coating

• Most of internal sliding parts are coated with proprietary Ultra-Low Friction Technology.
• Proprietary PDV coating of the shaft surface for durability and strength while reducing friction.
• Carbografite bushes and aeronautical seals design to keep perfect sliding and super low stiction
