Lead times vary by part and some items are built to order, so please allow extra time.

That means the compression and rebound rates match the actual loads and travel geometry of this truck at this lift height, so the suspension responds predictably whether the Tundra is loaded with gear on a washboard forest road or cruising empty on the highway.\u003c\/p\u003e\n\n\u003ch2\u003eInternal Bump Zone for High-Speed Control\u003c\/h2\u003e\n\u003cp\u003eICON's 6061 billet aluminum manifold, positioned a few inches below the top cap, creates an internal Bump Zone that adds 20% of damping force as the shock approaches full compression. That additional resistance helps prevent harsh bottom-outs during high-velocity compression events (landing a jump or dropping into a sudden rut at speed) without stiffening the shock through its normal travel range.\u003c\/p\u003e\n\n\u003ch2\u003eBuilt to Be Rebuilt and Retuned\u003c\/h2\u003e\n\u003cp\u003eThe V.S. 2.5 shocks are 100% rebuildable and 100% revalveable. A shock that can be serviced and revalved in the field or at a shop has a longer useful life and can be retuned if the truck's weight, lift, or use case changes. For buyers who want adjustable compression damping without replacing the shock body, these shocks are compatible with ICON's Compression Damping Control Valve (CDCV) upgrade.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOne-piece digressive piston:\u003c\/strong\u003e vehicle-specific valving for on- and off-road performance\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePiggyback reservoir:\u003c\/strong\u003e nitrogen-charged monotube design improves heat dissipation to reduce shock fade during extended use\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInternal Bump Zone:\u003c\/strong\u003e 6061 billet aluminum manifold increases damping by 20% near full compression\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e7\/8\" shock shaft:\u003c\/strong\u003e induction-hardened and chrome-plated for durability\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOne-piece impact-extruded aluminum cylinder:\u003c\/strong\u003e corrosion-resistant with consistent finish\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePTFE-lined spherical bearings:\u003c\/strong\u003e included with application-specific mounting hardware\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePremium 5WT shock oil:\u003c\/strong\u003e consistent damping across a wide temperature range\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\u003e57721P-CB\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eShock diameter\u003c\/td\u003e\n      \u003ctd\u003e2.5 in\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eShaft diameter\u003c\/td\u003e\n      \u003ctd\u003e7\/8 in, induction-hardened, chrome-plated\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eBody material\u003c\/td\u003e\n      \u003ctd\u003eOne-piece impact-extruded aluminum; 6061 aircraft-grade aluminum CNC-machined components\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\u003eNitrogen-charged monotube with piggyback reservoir\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eBump Zone damping increase\u003c\/td\u003e\n      \u003ctd\u003e20% additional damping force near full compression\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\u003eShip weight\u003c\/td\u003e\n      \u003ctd\u003e25 lb\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eVehicle fitment\u003c\/td\u003e\n      \u003ctd\u003e2007–2021 Toyota Tundra\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eLift height\u003c\/td\u003e\n      \u003ctd\u003e6 in rear\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 2007–2021 Toyota Tundra owners running 6 inches of rear lift who want a vehicle-specific damping tune, improved high-speed compression control, and a shock they can rebuild or revalve as their build evolves.\u003c\/p\u003e\n\u003cp class=\"product-fit-no\"\u003eThese shocks are not compatible with Tundra builds at other lift heights, with other Toyota models, or with any non-Tundra application.

Front shocks, coil springs, and upper control arms are not included and must be sourced separately to complete a full suspension upgrade.\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 inside the shock body that increases damping force by 20% as the shock nears full compression.
