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 in demanding environments.\u003c\/p\u003e\n\n\u003cp\u003eWith up to three distinct 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. The approximate raised height achieved with these springs ranges from 30-40mm, with specific ratings as follows: T85C for light loads (0-300kg), T85L for constant loads (300kg), and T85LL for heavier constant loads (500kg).\u003c\/p\u003e\n\n\u003cp\u003eIt is advisable to pair these raised springs with long travel shock absorbers to optimize performance. Constant load refers to weight that is permanently added to the vehicle, such as fixed accessories like canopies, steel trays, draw systems, fridges, toolboxes, rear bars, or spare wheel carriers. 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 accurately depict the specific part number you are viewing.\u003c\/p\u003e\u003ch4\u003eLeaf Spring Features\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eDesigned in Australia\u003c\/li\u003e\n\u003cli\u003eProgressive rate leaf springs\u003c\/li\u003e\n\u003cli\u003ePrimary and secondary stage leaves\u003c\/li\u003e\n\u003cli\u003ePrevents excessive sag\u003c\/li\u003e\n\u003cli\u003eMaximum life and corrosion protection\u003c\/li\u003e\n\u003cli\u003eUp to 3 spring rate options\u003c\/li\u003e\n\u003cli\u003ePrecision mandrel \u0026amp; die-formed\u003c\/li\u003e\n\u003cli\u003eOil quenched, hardened \u0026amp; tempered\u003c\/li\u003e\n\u003cli\u003eMilitary wrap standard\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\u003eSpring Rate Options\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eT85C - 0-300kg Light Load\u003c\/li\u003e\n\u003cli\u003eT85L - 300kg Constant Load\u003c\/li\u003e\n\u003cli\u003eT85LL - 500kg 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\u003c\/li\u003e\n\u003cli\u003eFixed accessories considered Constant Load\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: 30-40mm\n\u003cbr\u003e\n\u003cbr\u003e \tT85C - 0-300kg Light Load\n\u003cbr\u003e \tT85L - 300kg Constant Load\n\u003cbr\u003e \tT85LL - 500kg Constant Load\n\u003cbr\u003e \n\u003cbr\u003eSold Individually.\n\u003cbr\u003eWhere LH and RH are noted select one of each to create a pair.\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":46758942802094,"sku":"TD-T85L","price":383.15,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2136\/3225\/files\/Tough-Dog-Leaf-Springs-1_75554a39-6ad7-4ff4-95ec-e862b7efd1c3.jpg?v=1754614478","url":"https:\/\/ppdperformance.com.au\/products\/nissan-navara-2011-2015-d40-3-0l-stx-550-v6-2011-2015-tough-dog-t85l-tough-dog-rear-leaf-spring","provider":"PPD Performance","version":"1.0","type":"link"}
