Built-out vans often suffer harsh bottom-out from the constant weight they carry, and traditionally you had to order springs to a specific weight and lift before the build was even finished. Opti-Rate changes that with an industry-first tunable preload system, letting you dial in spring rate and ride height all in one package, a true 'one size fits all' solution for builders, installers, and step-by-step DIYers.\u003c\/p\u003e\n\u003ch6\u003eFeatures\u003c\/h6\u003e\n\u003cul\u003e\n\u003cli\u003eIndustry-first tunable preload system adjusts both spring rate and ride height\u003c\/li\u003e\n\u003cli\u003eThree-part design: primary main springs, a 3-leaf secondary stage, and billet Adjustable Preload Spacers (APS) with stackable delrin glide pads\u003c\/li\u003e\n\u003cli\u003eRun no APS for the softest ride, one glide pad for a firmer mid setting, or two for maximum rate and ride height\u003c\/li\u003e\n\u003cli\u003ePreload can be changed with just a floor jack, socket wrench, and mallet, springs stay on the van\u003c\/li\u003e\n\u003cli\u003eLengthened spring and longer shackle for a more stable, progressive curve and reduced leaf-spring harshness\u003c\/li\u003e\n\u003cli\u003eCompatible with lift blocks and existing rear geometry correction components for use with 2\" lift kits\u003c\/li\u003e\n\u003cli\u003eSold as a pair\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch6\u003eIncluded Components\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003eOpti-Rate Full Replacement Leaf Springs (matched pair)\u003c\/li\u003e\n\u003cli\u003e4 Billet Adjustable Preload Spacer Blocks\u003c\/li\u003e\n\u003cli\u003e4 Top preload spacers glide pads\u003c\/li\u003e\n\u003cli\u003e4 Middle preload spacers\u003c\/li\u003e\n\u003cli\u003eU-bolts and Nuts\u003c\/li\u003e\n\u003cli\u003eRear bump stop lower mounting bracket\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eImportant Notes\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003eThese require truck freight to ship; a commercial address helps save on shipping costs.\u003c\/li\u003e\n\u003cli\u003eProgressive rate leaf springs operate differently to factory style parabolic leaf springs.
