By using vehicle sensors and accelerometers, Live Valve can instantly adapt to inertial, steering, braking, and acceleration inputs to actively maximize handling, comfort, and bottom-out resistance. Three-way quick switch adjusters allow the shocks to be optimized for On-Road Performance, On-Road Comfort, or Off-Road Performance while the external cooling system ensures they will perform at their best when you are blasting through the desert. NEW Live Valve semi active technology equipped, plug and play integration to factory electronics NEW Rebound and compression adjustable via Quick Switch Technology (QS3) NEW Rotatable hose fittings for easy installation FOX patented, position-sensitive Internal Bypass damping technology Body 3.0″ impact extruded and CNC machined 6061-T6 hard-anodized aluminum body resists corrosion and weighs less than steel Body Plating Hard-anodized for a durable finish Reservoir Hard anodized aluminum finned remote reservoir (front) and piggyback reservoir and cooler (rear) resist corrosion and help dissipate heat fast. External fins act as heat sinks for increased heat dissipation.
