Designed specifically for built-out vans that carry constant weight, this system solves the common problems of harsh bottoming, poor ride quality, and mismatched spring rates.\u003c\/p\u003e\n\u003cp data-start=\"682\" data-end=\"1011\"\u003eTraditional leaf springs require choosing a fixed spring rate and lift height—often before a build is complete. The Opti-Rate system changes that entirely. With an \u003cstrong data-start=\"846\" data-end=\"887\"\u003eindustry-first tunable preload system\u003c\/strong\u003e, these springs allow you to dial in both spring rate and ride height as your build evolves, all using a single spring pack.\u003c\/p\u003e\n\u003cp data-start=\"1013\" data-end=\"1493\"\u003eEach Opti-Rate system consists of a primary main spring pack, a secondary 3-leaf stage, and \u003cstrong data-start=\"1105\" data-end=\"1141\"\u003eAdjustable Preload Spacers (APS)\u003c\/strong\u003e. The APS are precision-machined blocks with stackable Delrin glide pads that preload the secondary stage into the primary stage. For lighter vans, the springs run without APS for the softest ride. As weight increases, APS spacers can be added to progressively increase spring rate and restore ride height—without removing the springs from the vehicle.\u003c\/p\u003e\n\u003cp data-start=\"1495\" data-end=\"1850\"\u003eDesigned as a true correction system rather than excessive lift, the Opti-Rate springs restore lost ride height while maintaining proper suspension geometry. They are fully compatible with lift blocks and rear geometry correction components, making them an ideal foundation for 2\" lift kits when increased clearance or a more aggressive stance is desired.\u003c\/p\u003e","brand":"Van Compass","offers":[{"title":"Default Title","offer_id":42054291685461,"sku":"3037","price":1729.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0603\/5868\/8853\/files\/303601-MAIN_2296dd4e-3ad8-4703-b10f-06899d6efc7c.jpg?v=1767935135","url":"https:\/\/www.padoverland.com\/products\/opti-rate-replacement-leaf-springs-for-sprinter-2500-4x4-pair","provider":"PAD Overland","version":"1.0","type":"link"}
