Each shock is tuned in both length and damping specifically for this application, combining a nitrogen-charged monotube body with a piggyback reservoir for sustained off-road performance and a composed street ride.\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\u003eInternal Bump Zone Control\u003c\/h2\u003e\n\u003cp\u003eA 6061 billet aluminum manifold positioned a few inches below the top cap creates what ICON calls an internal Bump Zone. When the shock approaches full compression, this zone adds 20% more damping force. For a heavy-duty truck pushing through whoops or landing hard off a ledge, that extra resistance is the difference between a controlled compression and a harsh bottom-out that transfers directly to the frame and cab.\u003c\/p\u003e\n\n\u003ch2\u003eHeat Management Through the Piggyback Reservoir\u003c\/h2\u003e\n\u003cp\u003eProlonged off-road use generates heat in the shock fluid, and heat causes fade: the gradual loss of damping consistency that makes a truck feel loose and unpredictable after extended hard use. The piggyback reservoir increases fluid volume and surface area, dissipating heat faster and keeping damping behavior consistent across a full day of trail driving. Premium-grade 5WT shock oil maintains that consistency across a wide temperature range, from cold desert mornings to sustained high-speed running.\u003c\/p\u003e\n\n\u003ch2\u003eBuilt to Last and Be Serviced\u003c\/h2\u003e\n\u003cp\u003eThe shock body is precision-machined 1026 DOM steel with a CAD plating finish for corrosion resistance. The shaft is 7\/8-inch diameter, induction hardened and chrome plated. PTFE-lined spherical bearings handle articulation without binding. Every V.S. 2.5 Series shock is 100% rebuildable and 100% revalveable, so the investment in this pair can be maintained and retuned rather than replaced when the time comes.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVehicle-Specific Tune:\u003c\/strong\u003e length and damping valved specifically for 2001–2010 GM 2500\/3500 HD at 0–2.5\" front lift\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 bottom-outs\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePiggyback Reservoir:\u003c\/strong\u003e nitrogen-charged monotube with reservoir for improved heat dissipation and reduced shock fade\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e7\/8\" Hardened Shaft:\u003c\/strong\u003e induction hardened, chrome-plated shaft with PTFE-lined spherical bearings\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e1026 DOM Steel Body:\u003c\/strong\u003e CAD-plated, precision-machined for durability and corrosion resistance\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRebuildable and Revalveable:\u003c\/strong\u003e 100% serviceable for long-term use and future retuning\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\u003e77725P\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eSeries\u003c\/td\u003e\n      \u003ctd\u003eV.S. 2.5 Series\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\u003eShaft 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\u003e1026 DOM steel, CAD plated\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eManifold Material\u003c\/td\u003e\n      \u003ctd\u003e6061 billet aluminum\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\u003eDesign\u003c\/td\u003e\n      \u003ctd\u003eNitrogen-charged monotube with piggyback reservoir\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003ePiston\u003c\/td\u003e\n      \u003ctd\u003eOne-piece digressive design\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eBearings\u003c\/td\u003e\n      \u003ctd\u003ePTFE-lined spherical\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\u003eLift Range\u003c\/td\u003e\n      \u003ctd\u003e0–2.5\"\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003ePosition\u003c\/td\u003e\n      \u003ctd\u003eFront\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eVehicle Fitment\u003c\/td\u003e\n      \u003ctd\u003e2001–2010 GM 2500\/3500 HD\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eShipping Weight\u003c\/td\u003e\n      \u003ctd\u003e30 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 2001–2010 GM 2500\/3500 HD owners running 0–2.5 inches of front lift who want a significant damping upgrade over factory shocks for mixed on-road and off-road use, including high-speed dirt running where heat buildup and bottom-out resistance matter.\u003c\/p\u003e\n\u003cp class=\"product-fit-no\"\u003eThese shocks do not fit GM 2500\/3500 HD trucks outside the 2001–2010 model years, do not cover rear positions, and are not intended for lift heights above 2.5 inches on this application.

They are not a universal fitment and are not compatible with other model years or GM half-ton platforms.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eWhat does the piggyback reservoir do?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThe piggyback reservoir on these ICON 2.5 Series shocks increases fluid volume and heat-dissipation surface area compared to a standard monotube. During extended off-road use, this helps maintain consistent damping and reduces the fade that occurs when shock fluid overheats.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eWhat is the internal Bump Zone?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThe internal Bump Zone is created by a 6061 billet aluminum manifold positioned just below the top cap of each shock. As the shock nears full compression, this zone generates an additional 20% of damping force, helping prevent harsh bottom-outs under high-velocity compression.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eCan these shocks be rebuilt or revalved?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eYes. Every ICON V.S. 2.5 Series shock is 100% rebuildable and 100% revalveable. That means the shocks can be serviced and retuned over time rather than replaced outright, which extends the usable life of the pair.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eDoes this listing include mounting hardware?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eApplication-specific mounting hardware is included with these ICON V.S. 2.5 Series front shocks.
