Selecting the correct spring rate is critical for achieving optimal performance and ride quality from your Toughdog leaf springs. The spring rate should match your constant accessory load — the combined weight of permanently fitted equipment that your Ranger carries every day. Common rear accessories that affect spring selection include aluminium or steel canopies, steel tray bodies, toolboxes, drawer systems, secondary fuel tanks, dual battery setups, water tanks, roof racks with RTT (roof top tents), winches, bullbars, and towing equipment. Occasional loads such as camping gear, passengers, or periodic towing should NOT be included in your spring rate calculation, as selecting springs that are too heavy for your actual constant load will result in an overly firm ride and potential damage to other suspension components.
Professional installation by a qualified mechanic or experienced 4WD workshop is strongly recommended for leaf spring replacement to ensure correct torque specifications, spring seating, and safety. After installation, a full four-wheel alignment is mandatory as leaf spring replacement can affect rear axle alignment and consequently overall vehicle tracking. Allow a 500-kilometre break-in period for the springs to settle and reach their optimal ride height — some initial stiffness is normal as the leaves bed in together. When upgrading leaf springs on lifted vehicles or those with heavy accessories, consider pairing with upgraded control arms and extended shackles to maintain proper suspension geometry and articulation.
Toughdog has earned its reputation as one of Australia's most trusted suspension brands through decades of engineering excellence, real-world outback testing, and unwavering commitment to quality. Every Toughdog component is designed to handle the unique demands of Australian conditions — from corrugated gravel roads to extreme heat and dust. Backed by comprehensive warranty coverage and trusted by commercial fleets, emergency services, and touring enthusiasts nationwide, the Toughdog suspension range delivers proven performance you can rely on when you're hundreds of kilometres from help.
These Toughdog rear leaf springs are perfect for Ford Ranger PX3 owners who have added permanent accessories like canopies or trays, tradespeople carrying tools and equipment daily, caravan and camper trailer towers seeking improved stability, and touring enthusiasts planning extended remote travel with heavy camping gear. If you're experiencing rear sag, poor towing stability, or bottoming out under load, these springs restore proper ride height and load capacity. For those carrying extremely variable loads or wanting on-demand adjustability, consider supplementing leaf springs with airbag suspension for the ultimate in load versatility.

Yes, these Toughdog rear leaf springs are specifically engineered to fit all Ford Ranger PX3 models from 2018 to 2023, including XL, XLS, XLT, Wildtrak, and Raptor variants. The PX3 series uses a specific leaf spring design and mounting configuration that these springs are manufactured to match exactly. The springs will fit both single cab, super cab, and dual cab body styles. If you've made modifications to your Ranger's suspension or aren't sure about your vehicle's exact series, please contact our team who can verify fitment using your VIN or registration details.
The lift height provided by these Toughdog leaf springs depends on the spring rate you select and your vehicle's current constant load. Most customers experience between 0-50mm of lift compared to worn factory springs, with the primary purpose being to restore factory ride height when carrying accessories or provide additional load capacity. If your Ranger is currently sagging due to a canopy, toolbox, or other permanent accessories, these springs will typically restore it to factory height or slightly above. For specific lift measurements based on your vehicle's accessory setup, contact our suspension specialists who can recommend the appropriate spring rate for your desired outcome.
This kit includes a pair of Toughdog heavy-duty rear leaf springs (driver and passenger side), spring bushings, centre bolts with clips, anti-friction interleaf pads, and comprehensive fitting instructions. The springs come fully assembled and ready to install. Please note that U-bolts, spring shackles, and shock absorbers are not included and should be inspected during installation — worn components should be replaced to ensure optimal performance and safety. If your existing hardware shows signs of corrosion or wear, we recommend purchasing new U-bolts and shackles, which are available separately on our website.
Yes, Toughdog leaf springs are excellent for towing applications when you select the appropriate spring rate for your setup. These springs significantly reduce rear squat when towing, maintaining proper weight distribution between front and rear axles for improved stability, steering control, and braking performance. The progressive spring design provides comfort when unladen while firming up progressively under towing loads. When selecting your spring rate, consider your vehicle's constant accessory weight but do NOT factor in towing weight, as the springs are designed to handle towing forces dynamically. For frequent heavy towing or variable loads, consider supplementing with airbag suspension for on-demand adjustability.
For most standard applications on the Ford Ranger PX3, upgrading control arms is not mandatory when installing Toughdog leaf springs at factory or near-factory ride height. However, if you're installing these springs as part of a complete lift kit that raises your vehicle significantly, or if your existing control arms show wear, upgraded control arms are highly recommended to maintain proper suspension geometry and castor angles. Extended shackles may also be beneficial for vehicles with significant lift to improve rear axle articulation. Our suspension experts can assess your specific setup and recommend whether additional components would benefit your particular application and driving style.
Yes, a full four-wheel alignment is absolutely mandatory after installing new leaf springs on your Ford Ranger PX3. While leaf springs primarily affect the rear axle, changes in rear ride height can influence overall vehicle geometry and weight distribution, which affects front-end alignment settings. Additionally, the rear axle alignment should be checked to ensure proper tracking and to prevent premature tyre wear. Most reputable 4WD workshops will include alignment as part of the installation service. Driving without proper alignment after suspension work can lead to uneven tyre wear, poor handling, and reduced fuel efficiency.
Toughdog offers these leaf springs in multiple load ratings to match different constant accessory weights, and it's crucial to select the correct spring rate for YOUR specific vehicle setup. The spring rate you choose should be based on the permanent accessories your Ranger carries every day — canopy, toolboxes, drawer systems, etc. You cannot and should not change spring rates based on occasional loads or periodic towing, as installing springs that are too heavy for your actual constant load will result in an excessively harsh ride and potential damage to other suspension components. If you regularly alternate between very different load configurations, airbag suspension offers better adjustability than changing leaf springs.
These Toughdog leaf springs can provide additional clearance for larger tyres by restoring or slightly increasing rear ride height, particularly if your vehicle is currently sagging under accessory weight. However, tyre clearance is also heavily dependent on wheel offset, tyre width, suspension compression, and whether you've installed a complete lift kit including front suspension upgrades. Most Ranger PX3 owners can fit up to 32-inch tyres with appropriate lift and potentially minor trimming, while 33-inch tyres typically require more substantial modifications. For specific tyre fitment advice based on your complete suspension setup and wheel specifications, contact our team who can provide detailed clearance guidance.
Toughdog leaf springs are backed by a comprehensive manufacturer's warranty covering defects in materials and workmanship under normal use conditions. The specific warranty period and terms are detailed in the documentation included with your springs and cover issues such as manufacturing defects, premature sagging, or breakage under rated load conditions. The warranty does NOT cover damage from improper installation, overloading beyond the spring's rated capacity, accident damage, or normal wear and tear. To maintain warranty coverage, springs must be installed by a qualified mechanic according to Toughdog's specifications, and proof of installation may be required for warranty claims.
Absolutely — when correctly matched to your vehicle's constant load, Toughdog leaf springs provide excellent on-road comfort for daily driving while delivering the load capacity and durability needed for touring and work applications. The progressive multi-leaf design ensures the springs remain compliant over small bumps and road irregularities when lightly loaded, then progressively firm up as load increases. This provides a comfortable unladen ride for daily commuting while preventing excessive squat when loaded or towing. The key to achieving good ride quality is selecting the appropriate spring rate — springs that are too stiff for your actual constant load will feel harsh, which is why accurate load assessment is critical during spring selection.
