Engineered in Australia, these progressive rate leaf springs incorporate both primary and secondary stage leaves, ensuring that the vehicle's ride quality remains uncompromised under varying load conditions.\u003c\/p\u003e\n\n\u003cp\u003eAs the spring compresses under load, the secondary stage engages, effectively preventing excessive sag and maintaining optimal ride height. The manufacturing process is meticulously designed to maximize durability, offering robust corrosion resistance and sag prevention, ensuring longevity even under demanding conditions.\u003c\/p\u003e\n\n\u003cp\u003eWith up to three spring rate options available for most applications, these leaf springs provide the flexibility necessary to tailor the suspension setup to your specific vehicle requirements. Each spring is precision mandrel and die-formed, oil quenched, hardened, and tempered to guarantee extended service life.\u003c\/p\u003e\n\n\u003cp\u003eStandard features include military wrap across all part numbers, accurate heat treatment, and construction from high-grade spring steel. Many applications also incorporate anti-friction pads to enhance performance. The springs are pre-stressed to maintain ride height and are rigorously load rate tested to ensure reliability.\u003c\/p\u003e\n\n\u003cp\u003eFor vehicles equipped with additional accessories, various spring rates are available to accommodate constant load scenarios. This includes fixed accessories such as canopies, steel trays, draw systems, fridges, toolboxes, rear bars, or spare wheel carriers, which are all classified as constant load. The approximate raised height achieved with these springs ranges from 40-50mm, with specific ratings such as T83 for light loads (0-400kg) and T84 for constant loads (400kg).\u003c\/p\u003e\n\n\u003cp\u003eTo optimize performance, it is advisable to pair raised springs with long travel shock absorbers. Selecting the appropriate spring rate is crucial for achieving the best balance of load carrying capacity, ride quality, and ride height.\u003c\/p\u003e\n\n\u003cp\u003ePlease note that images provided are for representation purposes only and may not correspond directly to the specific part number being viewed.\u003c\/p\u003e\u003ch4\u003eFeatures of Tough Dog Leaf Springs\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eProgressive rate design with primary and secondary stage leaves\u003c\/li\u003e\n\u003cli\u003ePrevents excessive sag under load\u003c\/li\u003e\n\u003cli\u003eMaximum life and corrosion protection\u003c\/li\u003e\n\u003cli\u003eUp to 3 spring rate options available\u003c\/li\u003e\n\u003cli\u003ePrecision mandrel \u0026amp; die-formed\u003c\/li\u003e\n\u003cli\u003eOil quenched, hardened \u0026amp; tempered for longevity\u003c\/li\u003e\n\u003cli\u003eMilitary wrap standard across all part numbers\u003c\/li\u003e\n\u003cli\u003eAccurately heat-treated\u003c\/li\u003e\n\u003cli\u003eManufactured from high grade spring steel\u003c\/li\u003e\n\u003cli\u003eAnti-friction pads in most applications\u003c\/li\u003e\n\u003cli\u003ePre-stressed to maintain ride height\u003c\/li\u003e\n\u003cli\u003eDiamond cut ends\u003c\/li\u003e\n\u003cli\u003eLoad rate tested\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eLoad Options\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eApproximate Raised Height: 40-50mm\u003c\/li\u003e\n\u003cli\u003eT83 - 0-400kg Light Load\u003c\/li\u003e\n\u003cli\u003eT84 - 400kg Constant Load\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eImportant Notes\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eRecommend fitting long travel shock absorbers with raised springs\u003c\/li\u003e\n\u003cli\u003eConstant Load refers to weight that remains in\/on the vehicle at all times\u003c\/li\u003e\n\u003cli\u003eFixed accessories considered Constant Load include canopies, steel trays, draw systems, fridges, tool boxes, rear bars, or spare wheel carriers\u003c\/li\u003e\n\u003cli\u003eSelect the most relevant spring rate for best results\u003c\/li\u003e\n\u003c\/ul\u003e\u003cbr\u003eSelect the most appropriate spring rate option to suit the fixed accessories on the vehicle:\n\u003cbr\u003e\n\u003cbr\u003eApproximate Lift Height: 40-50mm\n\u003cbr\u003e\n\u003cbr\u003e \tT83 - 0-400kg Light Load\n\u003cbr\u003e \tT84 - 400kg Constant Load\n\u003cbr\u003e\n\u003cbr\u003eSold Individually.\u003cp\u003eHigh quality 4x4 suspension upgrades proudly sold by PPD Performance.\u003c\/p\u003e\u003ch5\u003eShipping Policy\u003c\/h5\u003e\n\u003cp\u003ePPD Performance offer custom built suspension solutions, with unique adjustability and performance.\u003c\/p\u003e\n\u003cp\u003eThese kits are assembled to order to suit your requirements, with an average lead time that can vary between 1-3 days.\u003c\/p\u003e\n\u003cp\u003eIf you need a specific eta, please contact us before ordering and we will be sure to assist you.\u003c\/p\u003e","brand":"Tough Dog","offers":[{"title":"Default Title","offer_id":46758931169454,"sku":"TD-T84","price":475.3,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2136\/3225\/files\/Tough-Dog-Leaf-Springs-1_a7fa2ed1-463c-4edc-9009-c8f1618e2214.jpg?v=1754614235","url":"https:\/\/ppdperformance.com.au\/products\/ford-f150-2015-2020-2015-2020-tough-dog-t84-raised-rear-leaf-spring","provider":"PPD Performance","version":"1.0","type":"link"}
