Selecting the correct spring rate is critical for optimal ride quality and suspension performance. You must calculate your constant accessory load — this includes only the weight of permanently fitted accessories carried 100% of the time. Common front accessories include steel bullbars, winches, upgraded batteries and long-range fuel tanks. Rear constant loads include aluminium canopies or steel trays, drawer systems, dual spare wheel carriers, long-range water tanks, and permanently mounted toolboxes. Do not include occasional loads such as camping gear, firewood, passengers, or towing weight — these are temporary loads. Selecting a spring rate too heavy for your actual constant load will result in a harsh, uncomfortable ride and may cause premature wear to other suspension components including shock absorbers and bushes.
Professional installation by a qualified mechanic or experienced 4WD workshop is strongly recommended for leaf spring replacement. The installation process involves supporting the vehicle chassis, removing old springs, fitting new bushes and shackles, and torquing all U-bolts and mounting hardware to manufacturer specifications. A full four-wheel alignment is mandatory after installation to ensure correct castor, camber and toe settings. Allow a 500km break-in period for springs to settle and bushes to seat properly before reassessing ride height and making any final adjustments. For vehicles with increased lift height or heavy constant loads, pairing these springs with upgraded control arms can further improve suspension geometry and steering performance.
Toughdog has earned its reputation as Australia's number one suspension brand through decades of proven performance in the toughest conditions our country can offer. Every Toughdog component is engineered and tested specifically for Australian vehicles, loads, and terrain — from corrugated outback tracks to coastal beach driving and daily urban commuting. Trusted by tradies, grey nomads, off-road tourers and 4WD enthusiasts nationwide, Toughdog backs their products with comprehensive warranty coverage and Australia-wide dealer support.

These rear leaf springs are ideal for Toyota Hilux N70 owners who regularly carry heavy loads, tow caravans or camper trailers, or have fitted significant rear accessories causing suspension sag. They're equally suited to tradies using their Hilux as a work vehicle with constant toolbox and equipment weight, touring families with permanent canopy and drawer setups, and recreational towers needing improved stability and load capacity. If you're experiencing rear-end sag, bottoming out over bumps when loaded, or poor towing stability, these springs will transform your Hilux's capability. For owners carrying highly variable loads, consider supplementing with airbag suspension for on-demand load adjustment.

Yes, these Toughdog rear leaf springs are specifically engineered for all Toyota Hilux N70 models manufactured between 2005 and 2015, including Single Cab, Extra Cab, and Dual Cab body configurations. They are direct OEM replacement springs with exact mounting dimensions and fitment specifications. The springs fit both 2WD and 4WD variants of the N70 Hilux. If you're unsure about your exact model year or have made modifications to your vehicle, our suspension experts can verify fitment for your specific Hilux.
These Toughdog rear leaf springs are primarily designed as heavy-duty replacement springs to restore factory ride height and improve load-carrying capacity rather than provide significant lift. Depending on the spring rate selected and your vehicle's current condition, you may see 0-30mm of lift when unladen, though the main benefit is maintaining proper ride height when loaded with accessories or towing. If you're seeking additional ground clearance, these springs work perfectly as part of a complete lift kit package that includes raised front coil springs or strut spacers. The actual ride height achieved depends on your constant accessory weight and selected spring rate.
This kit includes a pair of Toughdog heavy-duty rear leaf springs, spring centre bolts, new spring bushes and shackle bushes, U-bolts with nuts and washers, and all necessary mounting hardware for installation. The kit also includes detailed installation instructions with torque specifications. However, shock absorbers, shackles, shackle pins, and other suspension components are sold separately and should be inspected during installation. If your existing shackles or shock absorbers show wear, we recommend replacing them at the same time to maximize performance and avoid additional labour costs later.
Absolutely — these Toughdog rear leaf springs are specifically designed to handle the demands of regular towing including caravans, camper trailers, boat trailers and heavy equipment trailers. The heavy-duty spring construction and higher load ratings significantly improve rear-end stability, reduce suspension sag, and minimize body roll when towing at or near your Hilux's rated towing capacity. For optimal towing performance, ensure you select the spring rate that matches your constant rear accessory load, and consider pairing with upgraded shock absorbers for improved damping control. Many customers also add airbag suspension for fine-tuning load distribution when towing varying trailer weights.
Control arm upgrades are not mandatory when fitting these leaf springs as they primarily affect rear suspension, while control arms are front suspension components. However, if you're installing these springs as part of a complete lift kit that raises your entire vehicle, upgraded front upper control arms are highly recommended to correct castor angle and maintain proper steering geometry. Even without lift, if your Hilux has covered significant kilometres or shows signs of worn control arm bushes, replacement is wise during suspension work to avoid additional labour costs. Our team can advise on whether your specific setup would benefit from control arm upgrades.
Yes, a full four-wheel alignment is absolutely mandatory after installing new rear leaf springs on your Toyota Hilux N70. While leaf springs primarily affect rear suspension, changing rear ride height alters your vehicle's overall geometry and weight distribution, which impacts front-end alignment settings including castor, camber and toe. Driving without proper alignment after spring replacement will cause premature and uneven tyre wear, poor handling characteristics, and potential steering issues. Most reputable 4WD workshops include alignment in their installation quote, and the investment protects your new tyres and ensures optimal suspension performance and vehicle safety.
Yes, these Toughdog leaf springs are available in multiple load ratings — typically Light, Medium, and Heavy — to match your Toyota Hilux N70's specific constant accessory weight. During checkout, you'll select the appropriate spring rate based on your permanently fitted rear accessories such as canopies, drawer systems, dual spare carriers, water tanks and toolboxes. It's critical to select only based on constant load (accessories fitted 100% of the time), not occasional loads like camping gear or towing weight. Our suspension specialists can help calculate your constant load and recommend the ideal spring rate. Choosing too heavy a rating will result in harsh ride quality and potential component damage.
These rear leaf springs alone provide minimal to moderate lift (0-30mm depending on load and spring rate) and are primarily designed to restore ride height and improve load capacity rather than provide clearance for significantly larger tyres. If your goal is fitting substantially larger tyres, you'll need a complete lift kit that raises both front and rear suspension by 40-50mm or more. However, these springs as part of a complete Toughdog lift kit will support larger tyre fitment. The maximum tyre size depends on your total lift height, wheel offset, and whether you're willing to modify guards. Typical safe increases are 1-2 sizes above factory specifications without major modifications.
Toughdog provides comprehensive warranty coverage on these leaf springs, typically offering a lifetime warranty on spring breakage and a substantial warranty period on bushes and hardware components (specific terms vary by component). The warranty covers manufacturing defects and material failures under normal use conditions. Warranty claims require proof of purchase and professional installation with correct torque specifications. The warranty does not cover damage from accidents, improper installation, overloading beyond vehicle GVM, or use in competitive motorsport. Toughdog's Australia-wide dealer network ensures warranty support regardless of where you're travelling, giving you peace of mind on long-distance touring adventures.
Yes, these Toughdog leaf springs are designed to provide excellent ride quality for daily driving, urban commuting, and highway cruising, not just off-road or heavy-duty applications. When correctly matched to your constant accessory load, they deliver a comfortable unladen ride while maintaining capability when loaded. The progressive spring design means they're compliant over small bumps and road imperfections during daily driving, yet provide strong support when carrying payloads or towing on weekends. Many Hilux owners use their vehicles as both daily drivers and weekend tourers, and these springs excel in that dual-purpose role, offering durability and comfort without compromising everyday drivability or fuel economy.
