Sold as a pair, these shocks combine a 2.5\" hard-anodized aluminum body, a piggyback reservoir, and ICON's Compression Damping Electronic Valve (CDEV) for electronically adjustable damping from inside the cab.\u003c\/p\u003e\n\u003cp class=\"product-shipping-note\"\u003e\u003cstrong\u003eShipping:\u003c\/strong\u003e ICON parts ship direct from ICON Vehicle Dynamics, mostly by UPS Ground. Lead times vary by part and some items are built to order, so please allow extra time. We email tracking as soon as your order ships.\u003c\/p\u003e\n\n\u003ch2\u003eBump Zone Technology Prevents Harsh Bottom-Outs\u003c\/h2\u003e\n\u003cp\u003eA 6061-billet aluminum manifold positioned just below the top cap creates an internal Bump Zone that adds 20% more damping force as the shock approaches full compression. On rough terrain or during high-velocity suspension events, that extra resistance keeps the suspension from bottoming harshly. The difference is meaningful when a loaded Ram 2500 hits a washboard or a sudden drop at speed.\u003c\/p\u003e\n\n\u003ch2\u003eElectronically Adjustable Damping via CDEV\u003c\/h2\u003e\n\u003cp\u003eThe Compression Damping Electronic Valve reacts in under 40 milliseconds and adjusts oil flow infinitely across its range, so damping force changes with terrain rather than staying fixed at one compromise setting. The valve's hydraulic circuits are calibrated specifically for the Ram 2500 application to maximize resolution and dynamic range for this truck. The system is powered by the ICON Intelligent Control app and uses onboard G-force sensor and gyroscope data to predict terrain and adjust settings automatically, and the driver can also set preferences manually from inside the vehicle.\u003c\/p\u003e\n\n\u003ch2\u003eBuilt to Last and Be Serviced in the Field\u003c\/h2\u003e\n\u003cp\u003eThe shock body is a one-piece, impact-extruded aluminum cylinder with a hard-anodized finish for corrosion resistance. The 7\/8\" shock shaft is induction-hardened and chrome-plated. PTFE-lined spherical bearings handle articulation at the mounting points. Premium 5WT shock oil maintains consistent damping across a wide temperature range. Every V.S. 2.5 Aluminum Series shock is fully rebuildable and re-tunable, so the investment extends well beyond a single service interval.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCDEV electronic valve:\u003c\/strong\u003e infinitely variable compression damping, reacts in under 40ms, adjustable from inside the cab via ICON Intelligent Control app\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInternal Bump Zone:\u003c\/strong\u003e 6061-billet aluminum manifold adds 20% damping force near full compression to resist harsh bottom-outs\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePiggyback reservoir:\u003c\/strong\u003e improves heat dissipation to reduce shock fade during extended off-road use\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHard-anodized aluminum body:\u003c\/strong\u003e one-piece impact-extruded cylinder with corrosion-resistant finish\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e7\/8\" chrome-plated shaft:\u003c\/strong\u003e induction-hardened for durability; PTFE-lined spherical bearings at mounting points\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFully rebuildable and re-tunable:\u003c\/strong\u003e length and damping tune optimized specifically for this Ram 2500 application\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\n    \u003ctr\u003e\n      \u003cth\u003eSpecification\u003c\/th\u003e\n      \u003cth\u003eDetail\u003c\/th\u003e\n    \u003c\/tr\u003e\n  \u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eSKU\u003c\/td\u003e\n      \u003ctd\u003e217706EP\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eVehicle Fitment\u003c\/td\u003e\n      \u003ctd\u003e2014–2026 Ram 2500 (no factory rear air ride)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003ePosition\u003c\/td\u003e\n      \u003ctd\u003eRear\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eQuantity\u003c\/td\u003e\n      \u003ctd\u003ePair (2 shocks)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eShock Body Diameter\u003c\/td\u003e\n      \u003ctd\u003e2.5\"\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eShock Shaft Diameter\u003c\/td\u003e\n      \u003ctd\u003e7\/8\"\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eBody Material\u003c\/td\u003e\n      \u003ctd\u003eHard-anodized impact-extruded aluminum (one-piece)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eManifold Material\u003c\/td\u003e\n      \u003ctd\u003e6061 aircraft-grade billet aluminum (CNC machined)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eShock Oil\u003c\/td\u003e\n      \u003ctd\u003ePremium grade 5WT\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eCDEV Response Time\u003c\/td\u003e\n      \u003ctd\u003eUnder 40ms\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRequired Companion Parts\u003c\/td\u003e\n      \u003ctd\u003eICON 2\" Lift Performance Rear Coil Springs (p\/n 214202); applicable IIC kit; CDEV front shocks\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eApp Requirement\u003c\/td\u003e\n      \u003ctd\u003eiOS device required for ICON Intelligent Control app\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eShipping Weight\u003c\/td\u003e\n      \u003ctd\u003e33 lb\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eWho This Is For and Isn't\u003c\/h2\u003e\n\u003cp class=\"product-fit-yes\"\u003eThese shocks suit 2014–2026 Ram 2500 owners who are already running or planning to install ICON's 2\" Lift Performance Rear Coil Springs (p\/n 214202) and want electronically adjustable rear damping for mixed on-road and off-road driving.
