Choosing the correct leaf spring load rating is critical to achieving optimal ride quality, durability and performance. Select your spring rate based on the constant accessory weight permanently installed on your Hilux — not occasional cargo or towing loads. Common rear constant loads include canopies (40-80kg), drawer systems (60-120kg), long-range fuel tanks (40-60kg empty), dual battery setups (20-30kg), fridge slides and storage systems (30-50kg), and service bodies or trade fitouts (80-200kg). Add these weights together to determine your constant rear axle load, then select the spring option that matches this weight category. Choosing a spring rated too heavy for your application will result in a harsh ride, increased wear on suspension components, and poor handling characteristics.
Professional installation by a qualified suspension specialist or experienced mechanic is strongly recommended for leaf spring replacement to ensure correct fitment, torque specifications and safety. A full four-wheel alignment is mandatory after installation to ensure correct steering geometry, prevent uneven tyre wear and maintain proper handling characteristics. All leaf springs require a 500km break-in period during which ride height will settle slightly as components bed in — avoid extreme loads during this initial period. For vehicles with 50mm or greater lift, we recommend pairing your new leaf springs with upgraded control arms to maintain correct suspension geometry and maximize wheel travel and handling performance.
Dobinsons has been engineering and manufacturing premium 4WD suspension for over 60 years, with deep roots in Australian outback testing and real-world touring applications. Every Dobinsons leaf spring is designed to handle Australia's unique combination of heavy loads, extreme temperatures, corrugated roads and remote touring conditions that destroy inferior products. Backed by comprehensive manufacturer warranty and trusted by thousands of Australian tradespeople, tourers and off-road enthusiasts, the full Dobinsons suspension range represents proven reliability you can depend on when you're hundreds of kilometers from the nearest town.
These Dobinsons leaf springs are ideal for Hilux N70 owners who use their vehicle for trade work with constant tool and equipment loads, regular towing of caravans or trailers, remote touring with camping gear and recovery equipment, or simply need to restore ride height and handling after years of heavy use. If you frequently carry variable loads or tow different trailers, consider pairing your leaf springs with airbag suspension for on-demand adjustability and load-leveling capability without compromising unladen ride quality.

Yes, these Dobinsons leaf springs are specifically engineered for the Toyota Hilux N70 series (chassis code KUN26) manufactured between 2005 and 2015. They are compatible with all body configurations including single cab, extra cab and dual cab variants. If you have a non-standard vehicle configuration or aftermarket modifications, we recommend checking fitment with our team before ordering to ensure perfect compatibility with your specific setup.
Dobinsons leaf springs for the Hilux N70 are available in multiple lift height options including approximately 25mm, 50mm, or 75mm over factory ride height depending on the specific spring model selected. The actual lift achieved will vary based on your vehicle's current accessory load and the condition of your existing suspension components. Vehicles with heavy constant loads will experience less lift than unladen vehicles, and heavier-rated springs will sit higher when unladen compared to lighter-rated options.
This leaf spring set includes a matched pair of complete rear leaf spring assemblies (driver and passenger side), spring centre bolts with clips, and anti-squeak Teflon pads to reduce friction between leaves. U-bolts, greasable shackles, pins and leaf spring bushes are not included but are available as optional upgrades and highly recommended for replacement during installation. Replacing all mounting hardware ensures maximum service life and optimal performance from your new leaf springs.
Absolutely — Dobinsons leaf springs are engineered specifically to improve towing stability and reduce rear-end sag when hauling heavy loads. The correct spring rate will maintain proper suspension geometry under towing loads, improving handling, braking performance and overall vehicle control. However, you should select your spring rate based on constant accessory weight only, not towing weight, as occasional towing loads should not dictate your spring choice. For maximum towing versatility with different trailer weights, consider adding airbag suspension for on-demand load adjustment.
Control arm upgrades are not mandatory for leaf spring replacement, but they are highly recommended when installing leaf springs that provide 50mm or greater lift. Upgraded control arms help maintain correct suspension geometry at increased ride heights, prevent ball joint and CV axle binding, and maximize wheel travel for improved off-road capability. Factory control arms can limit suspension articulation and create geometry issues when combined with significant lift, so upgrading them ensures you get the full performance benefit from your new leaf springs.
Yes — a full four-wheel alignment is mandatory after installing new leaf springs to ensure correct steering geometry and prevent premature tyre wear. Changing ride height affects camber, caster and toe angles which directly impact handling, braking and tyre life. Professional alignment by a qualified workshop with experience in modified 4WD vehicles is essential, and you should specify that your vehicle has been lifted so they can set alignment to appropriate specifications for your new ride height.
Select your leaf spring load rating based on the total weight of permanent accessories installed on the rear of your vehicle — not occasional cargo or towing weight. Calculate your constant rear load by adding up items like canopies, drawer systems, long-range fuel tanks (empty weight), dual batteries, fridges, and service bodies or toolboxes. Match this total weight to the appropriate spring load category — choosing springs rated too heavy for your actual load will result in a harsh, uncomfortable ride and increased component wear, while springs rated too light will sag and fail to provide adequate support.
The increased ride height from Dobinsons leaf springs will typically provide clearance for slightly larger tyres than factory specifications, though the exact size depends on your chosen lift height and wheel offset. As a general guide, 25mm of lift allows approximately 1 inch larger diameter tyres, while 50mm lift can accommodate around 2 inches larger. However, tyre fitment is also affected by wheel offset, guard design and suspension articulation, so test-fit your intended tyres before purchase or consult with experienced Hilux builders to confirm clearance for your specific wheel and tyre combination.
Dobinsons leaf springs are covered by a comprehensive manufacturer's warranty against defects in materials and workmanship, providing peace of mind for your investment in quality suspension components. Warranty terms vary by product line and application, so contact our team for specific warranty details for your chosen leaf spring model. To maintain warranty coverage, professional installation by a qualified mechanic is required, and you must use the springs within their designed load rating and operating parameters — overloading or improper use will void warranty coverage.
Yes — when correctly matched to your vehicle's constant load, Dobinsons leaf springs provide excellent on-road comfort for daily driving, highway cruising and long-distance touring. Dobinsons engineers their springs to balance load-carrying capability with ride quality, avoiding the harsh, jarring ride associated with overrated or poorly designed springs. Parabolic leaf spring options offer enhanced comfort through their tapered design, reducing unsprung weight and improving road manners. However, if you choose springs rated significantly higher than your actual constant load, you will experience a firmer ride when unladen compared to factory springs.
Sorted My Sagging Rear End Properly
Been running these Dobinsons heavy-duty leaf springs on my N70 for about 18 months now, including two Cape York trips and countless outback tracks through the Simpson and Flinders. The difference in load carrying capacity is night and day - no more sagging with a full water setup, recovery gear, and camping kit in the tray. Fitment was spot-on and they've maintained their ride height perfectly even after the punishment I've given them on corrugated tracks.(5)
Perfect upgrade for our loaded Hilux
These Dobinsons heavy-duty leaf springs have completely transformed how our 2012 Hilux handles when we're loaded up for camping trips down the coast. The rear end no longer sags with the camper trailer hitched up and all the family gear in the tub. Fitment was spot-on and the ride quality is noticeably better than the worn-out factory springs they replaced, especially on corrugated tracks.(5)
