Each shock is individually tuned in both length and damping for this exact application, and the piggyback reservoir design keeps heat out of the main shock body so damping stays consistent during extended off-road use.\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.

As the shock approaches full compression, this zone adds 20% more damping force, which means the suspension resists harsh bottom-outs during high-velocity compression events like landing a jump or dropping into a rut at speed. That extra resistance is automatic and requires no driver input or external adjustment.\u003c\/p\u003e\n\n\u003ch2\u003eHeat Management Through Reservoir Design\u003c\/h2\u003e\n\u003cp\u003eThe piggyback reservoir separates a portion of the shock oil and nitrogen charge from the main body, giving heat generated during hard use more surface area to dissipate. This reduces shock fade, the gradual loss of damping feel that occurs when oil overheats, during prolonged off-road runs. The shock uses premium-grade 5WT shock oil, which maintains consistent damping across a wide temperature range from cold morning starts to sustained trail use.\u003c\/p\u003e\n\n\u003ch2\u003eBuilt to Be Serviced, Not Replaced\u003c\/h2\u003e\n\u003cp\u003eThe V.S. 2.5 Series shocks are 100% rebuildable and 100% revalveable. The 7\/8-inch induction-hardened, chrome-plated shock shaft resists wear and corrosion, and the 1026 DOM steel shock body is CAD plated for durability. When driving style or terrain changes, the valving can be reworked rather than the shock replaced. These shocks can also be upgraded to ICON's Compression Damping Control Valve (CDCV) for a more user-defined compression tune.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\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 nitrogen-charged monotube with separate reservoir reduces heat buildup and shock fade\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVehicle-specific valving:\u003c\/strong\u003e one-piece digressive piston tuned in length and damping for 2004–2008 Ford F-150 2WD at 0–3\" lift\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDurable construction:\u003c\/strong\u003e 7\/8\" chrome-plated induction-hardened shaft, CAD-plated 1026 DOM steel body, CNC-machined 6061 aluminum components\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRebuildable and revalveable:\u003c\/strong\u003e fully serviceable; CDCV upgrade available for adjustable compression damping\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePTFE-lined spherical bearings\u003c\/strong\u003e and application-specific mounting hardware included\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\u003e97710P\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eFitment\u003c\/td\u003e\n      \u003ctd\u003e2004–2008 Ford F-150 2WD\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eLift Range\u003c\/td\u003e\n      \u003ctd\u003e0–3 inches\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 inches\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eShock Shaft Diameter\u003c\/td\u003e\n      \u003ctd\u003e7\/8 inch\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\u003eShock Body Material\u003c\/td\u003e\n      \u003ctd\u003e1026 DOM steel, CAD plated\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eAluminum Components\u003c\/td\u003e\n      \u003ctd\u003e6061 aircraft-grade, 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\u003eReservoir Type\u003c\/td\u003e\n      \u003ctd\u003ePiggyback\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eDesign\u003c\/td\u003e\n      \u003ctd\u003eNitrogen-charged monotube\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003ePiston\u003c\/td\u003e\n      \u003ctd\u003eOne-piece digressive\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\u003eShip Weight\u003c\/td\u003e\n      \u003ctd\u003e30 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 2004–2008 Ford F-150 2WD owners running 0–3 inches of lift who want a significant rear suspension upgrade for mixed on-road and off-road use, particularly those who run trails, graded roads, or high-speed dirt where heat buildup and bottom-out resistance matter.\u003c\/p\u003e\n\u003cp class=\"product-fit-no\"\u003eThese shocks do not fit 4WD F-150 variants, F-150s outside the 2004–2008 model years, or trucks lifted more than 3 inches.

They are not compatible with 4WD models or F-150s outside that model-year range, and the valving and length are calibrated for that exact application.\u003c\/p\u003e\n\u003ch3 class=\"product-faq-q\"\u003eWhat does the piggyback reservoir actually do?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThe piggyback reservoir on these ICON 2.5 Series shocks holds a portion of the oil and nitrogen charge outside the main shock body, increasing the total surface area available to shed heat. This reduces shock fade, the gradual softening of damping that occurs when shock oil overheats during sustained hard use on trails or washboard roads.\u003c\/p\u003e\n\u003ch3 class=\"product-faq-q\"\u003eCan the damping be adjusted after installation?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eAs shipped, these shocks have fixed compression damping tuned for the 2004–2008 F-150 2WD application. They can be upgraded to ICON's Compression Damping Control Valve (CDCV), which adds external compression adjustment. The CDCV is a separate purchase and is not included with SKU 97710P.\u003c\/p\u003e\n\u003ch3 class=\"product-faq-q\"\u003eAre these shocks rebuildable, and what does that mean in practice?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThe ICON V.S. 2.5 Series shocks are 100% rebuildable and 100% revalveable. Rebuild means the seals, oil, and nitrogen charge can be replaced when the shock wears rather than discarding the unit. Revalveable means the internal piston shims can be reconfigured by a qualified shop to change the damping character if your use case or lift height changes.\u003c\/p\u003e\n\u003ch3 class=\"product-faq-q\"\u003eIs this a front and rear kit, or rear only?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eSKU 97710P is a rear-only pair: two shocks for the rear axle of a 2004–2008 Ford F-150 2WD.
