The system pairs VS 2.5 Series remote reservoir front coilovers with dual-rate rear coil springs, tubular DOM rear lower links, and 2.5 Aluminum Series rear remote reservoir shocks for balanced, rebuildable performance on- and off-road.\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.

This Stage 4 system uses a vehicle-specific coilover length and valving that works directly with the stock TRD Pro billet aluminum UCAs, preserving the OEM geometry investment while adding a larger 2.5\" shock body and increased piston area. The result is maximum wheel travel without overstressing factory components, a meaningful difference for buyers who want improved capability without discarding parts that came on the truck.\u003c\/p\u003e\n\n\u003ch2\u003eRemote Reservoirs Front and Rear\u003c\/h2\u003e\n\u003cp\u003eBoth the front coilovers and the rear 2.5 Aluminum Series shocks carry remote reservoirs. The added oil volume and heat-dissipation surface area resist the overheating and cavitation that cause damper fade under sustained hard use: washboard roads, repeated water crossings, or loaded highway miles in summer heat. The rear shocks also incorporate an internal Bump Zone that adds 20% of damping force at the end of travel to resist hard bottom-outs, a practical benefit when the Sequoia is loaded with passengers or gear.\u003c\/p\u003e\n\n\u003ch2\u003eRear End Rebuilt for Level Stance and Articulation\u003c\/h2\u003e\n\u003cp\u003eThe dual-rate rear coil springs use a softer primary rate for on-road comfort and a firmer overload rate for bottoming resistance, producing 2\" of rear lift on a stock TRD Pro. That 2\" of rear lift levels the stance front to rear when the front is set at its full 2.5\" adjustment. The tubular rear lower links, made from 1-3\/4\" x .313-wall DOM steel tubing with a multi-stage black powder coat, add PTFE-lined FK rod ends for increased articulation and reduced deflection, plus multi-durometer bushings that require no periodic greasing.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAdjustable front lift:\u003c\/strong\u003e 1-2.5\" of front ride height adjustability over stock\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTRD Pro UCA compatible:\u003c\/strong\u003e vehicle-specific coilover length designed for stock billet aluminum front upper control arms\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRemote reservoirs front and rear:\u003c\/strong\u003e increased oil volume and heat dissipation on all four corners\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRear Bump Zone:\u003c\/strong\u003e internal feature on 2.5 Aluminum Series rear shocks adds 20% damping force at end of travel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTubular DOM rear lower links:\u003c\/strong\u003e 1-3\/4\" x .313-wall tubing, PTFE-lined FK rod ends, multi-durometer bushings, black powder coat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFully rebuildable:\u003c\/strong\u003e all ICON shock absorbers in this system are rebuildable and re-tunable\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\u003eK53394T\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eVehicle Fitment\u003c\/td\u003e\n      \u003ctd\u003e2023-2026 Toyota Sequoia TRD Pro\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eFront Lift Range\u003c\/td\u003e\n      \u003ctd\u003e1-2.5\" over stock (stock-equipped vehicle)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRear Lift\u003c\/td\u003e\n      \u003ctd\u003e2\" over stock on Sequoia TRD Pro (stock-equipped vehicle)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eFront Shocks\u003c\/td\u003e\n      \u003ctd\u003eVS 2.5 Series remote reservoir coilovers (part 58772)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRear Springs\u003c\/td\u003e\n      \u003ctd\u003eDual-rate rear coil springs (part 51216)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRear Lower Links\u003c\/td\u003e\n      \u003ctd\u003eTubular DOM 1-3\/4\" x .313-wall, black powder coat, PTFE-lined FK rod ends (part 54002T)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRear Shocks\u003c\/td\u003e\n      \u003ctd\u003e2.5 Aluminum Series remote reservoir shocks with Bump Zone (part 57840P)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRear Lower Link Tubing\u003c\/td\u003e\n      \u003ctd\u003e1-3\/4\" x .313-wall DOM steel\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eShip Weight\u003c\/td\u003e\n      \u003ctd\u003e134 lb\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRecommended Aftermarket Wheels\u003c\/td\u003e\n      \u003ctd\u003eICON Alloys 17x8.5\" (5.75\" backspace \/ 25mm offset) or 18x9\" (6\" backspace \/ 25mm offset)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRecommended Aftermarket Tires\u003c\/td\u003e\n      \u003ctd\u003e35\" x 12.50\" (minor fender trimming and modifications may be required)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eOEM Wheels and Tires Fitment\u003c\/td\u003e\n      \u003ctd\u003eYes\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\"\u003eThis system suits 2023-2026 Toyota Sequoia TRD Pro owners who want 1-2.5\" of adjustable front lift and a level rear stance while keeping the factory billet aluminum front upper control arms.
