Each shock features ICON's externally adjustable CDC Valve and an internal Bump Zone for high-velocity compression control.\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.

Turning a single knob lets a driver dial in a softer setting for daily highway miles or a firmer setting before a washboard forest road, without removing a wheel or opening the shock body. That range of adjustment means one set of shocks can serve the same truck across genuinely different use cases rather than forcing a compromise at the factory middle.\u003c\/p\u003e\n\n\u003ch2\u003eBump Zone and Piggyback Reservoir for High-Speed Control\u003c\/h2\u003e\n\u003cp\u003eA 6061 billet aluminum manifold positioned just below the shock's top cap creates an internal Bump Zone that adds 20% of damping force as the shock approaches full compression. At high velocity off-road, that extra resistance helps prevent harsh bottom-outs that can unsettle the truck or damage cargo. The piggyback reservoir separates the oil volume from the main shock body, improving heat dissipation and reducing shock fade during extended hard use on rough terrain.\u003c\/p\u003e\n\n\u003ch2\u003eRebuildable Construction Built to Last\u003c\/h2\u003e\n\u003cp\u003eThe shock body is a one-piece impact-extruded aluminum cylinder, CNC machined from 6061 aircraft-grade aluminum, which resists corrosion and holds tight tolerances over years of use. The 7\/8\" induction-hardened, chrome-plated shock shaft resists bending and surface wear. Every V.S. 2.5 Aluminum Series shock is 100% rebuildable and 100% revalveable, so the shock can be serviced or retuned rather than replaced when it eventually needs attention. Premium 5WT shock oil maintains consistent damping across a wide temperature range.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCDC Valve:\u003c\/strong\u003e 10-level externally adjustable compression damping with a single knob\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePiggyback Reservoir:\u003c\/strong\u003e nitrogen-charged monotube with separate reservoir for improved heat dissipation\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e7\/8\" Shock Shaft:\u003c\/strong\u003e induction-hardened, chrome-plated for durability and corrosion resistance\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRebuildable and Revalveable:\u003c\/strong\u003e 100% serviceable; vehicle-specific length and damping tune for the Ram 2500\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOE-Style Mounting:\u003c\/strong\u003e polyurethane bushings, forged steel stems, PTFE-lined spherical bearings, and application-specific hardware\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\u003eVehicle Fitment\u003c\/td\u003e\n      \u003ctd\u003e2014–2026 Ram 2500\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\u003eShaft Finish\u003c\/td\u003e\n      \u003ctd\u003eInduction hardened, chrome plated\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eBody Material\u003c\/td\u003e\n      \u003ctd\u003e6061 aircraft-grade aluminum, CNC machined, impact extruded\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eReservoir Type\u003c\/td\u003e\n      \u003ctd\u003ePiggyback\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eCharge Type\u003c\/td\u003e\n      \u003ctd\u003eNitrogen-charged monotube\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eCompression Adjustment\u003c\/td\u003e\n      \u003ctd\u003e10-level CDC Valve (externally adjustable)\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\u003eOptimized Lift Height\u003c\/td\u003e\n      \u003ctd\u003e0.5\" (tuned for ICON Lift Performance Rear Coil Springs, PN 214206)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eSKU\u003c\/td\u003e\n      \u003ctd\u003e217705CP\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eShipped Weight\u003c\/td\u003e\n      \u003ctd\u003e28 lb (pair)\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 running ICON's 0.5\" Lift Performance Rear Coil Springs (PN 214206) who want externally adjustable, rebuildable rear damping for mixed on-road and off-road use.\u003c\/p\u003e\n\u003cp class=\"product-fit-no\"\u003eThese shocks are not compatible with Ram 2500 trucks equipped with factory rear air ride suspension.

They are designed for the standard coil-spring rear suspension found on 2014–2026 Ram 2500 models without the air ride option.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eAre the coil springs included with this purchase?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eNo. This listing covers the pair of rear shock absorbers only. The shocks are tuned specifically for use with ICON's 0.5\" Lift Performance Rear Coil Springs, part number 214206, which must be purchased separately. Running these shocks with a different spring height may affect damping performance.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eHow does the CDC Valve compression adjustment work?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThe ICON CDC Valve is an externally accessible knob on the piggyback reservoir that restricts oil flow between the shock body and the reservoir. Turning the knob cycles through 10 levels of compression damping force, from softer settings suited to highway driving to firmer settings for high-speed off-road use, without disassembling the shock.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eCan these shocks be rebuilt or revalved if they wear out?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eYes. Every ICON V.S. 2.5 Aluminum Series shock is 100% rebuildable and 100% revalveable. The one-piece impact-extruded aluminum body and serviceable internals mean the shock can be disassembled, seals replaced, and valving changed by a qualified shop rather than requiring full replacement.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eWhat is the Bump Zone, and why does it matter?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThe Bump Zone is created by a 6061 billet aluminum manifold positioned just below the shock's top cap. As the shock approaches full compression, this manifold increases damping force by 20%, helping prevent harsh bottom-outs during high-velocity impacts off-road. The result is better control and reduced shock to the truck's frame and cab when hitting sharp terrain features at speed.\u003c\/p\u003e","brand":"ICON Vehicle Dynamics","offers":[{"title":"Default Title","offer_id":50629343313990,"sku":"217705CP","price":1482.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0691\/2203\/1686\/files\/0ea5ec7cdee4259b0e9cc1a204e4b9c4_ee7ebf4e-a389-487c-8282-a64-sq.jpg?v=1791945459","url":"https:\/\/terrainvault.com\/products\/icon-v-s-2-5-aluminum-rear-piggyback-shocks-with-cdcv-for-2014-2026-ram-2500","provider":"TerrainVault","version":"1.0","type":"link"}
