These shocks are configured specifically for each application in both length and damping tune. Like all ICON'S Shock Absorbers, V.S. 2.5 Aluminum Series shocks are 100% rebuildable and 100% revalveable. The larger diameter and oil volume of ICON 2.5 IR Series shocks provide better ride quality and heat dissipation properties than the standard 2.0 Aluminum Series IR Shocks. If you are looking for a more user defined tune, consider looking into the Compression Damping Control Valve (CDC Valve) shocks.\u003c\/p\u003e\n\u003c\/div\u003e\u003cdiv class=\"hs-why\"\u003e\n\u003ch3\u003eWhy this 2.5 Series VS IR Rear Shocks\u003c\/h3\u003e\n\u003cp\u003eICON VS (Vehicle Specific) shocks are built to the exact length and valving for a 1999-2026 Ford F-250\/F-350 Super Duty at the lift height listed, so they run in the middle of their travel instead of topping out or bottoming early.

RR is a remote reservoir connected by hose and PB is a piggyback reservoir bolted to the body; both add oil volume and cooling so damping stays consistent on long rough sections. IR is lighter and simpler; RR and PB resist fade.\u003c\/p\u003e\u003c\/details\u003e\u003cdetails\u003e\u003csummary\u003eCDCV, CDEV, CDXS: which adjuster?\u003c\/summary\u003e\u003cp\u003eCDCV is a 10-position manual compression knob. CDEV is an electronic compression valve controlled by the ICON Intelligent Control module and phone app, which reads speed and terrain and adjusts on the fly; it requires the IIC install kit. CDXS is a manual dual-circuit adjuster with 10 marked detents each for compression and rebound. Shocks without a code run ICON's fixed vehicle-specific valving.\u003c\/p\u003e\u003c\/details\u003e\u003cdetails\u003e\u003csummary\u003eCan these be serviced?\u003c\/summary\u003e\u003cp\u003eYes.
