Dobinsons Monotube Quick-Lift Kit for Nissan Navara D40 — Complete Suspension Upgrade

The Dobinsons Monotube Quick-Lift Kit delivers approximately 2 inches (50mm) of lift at both front and rear, providing a level stance when measured from the factory ride height with standard loads. Actual lift height can vary by 10-15mm depending on your selected spring rates, current vehicle weight, and constant accessory loads fitted to your Navara. The extended rear shackles contribute to the rear lift while maintaining proper spring geometry and articulation. This moderate lift height improves ground clearance and allows fitment of up to 32-inch tyres in most cases without requiring extensive body modifications or diff drops, though final tyre clearance depends on wheel offset and trimming.

This complete kit includes two pre-assembled front monotube struts with matched coil springs already installed, two rear monotube shock absorbers, and two heavy-duty 2-inch extended greasable shackles for the rear leaf springs. All necessary mounting hardware is supplied for straightforward installation. The pre-assembled front struts are a major time-saver, eliminating the need for dangerous spring compression during installation. Note that this kit does not include upper control arms, extended brake lines, diff drop components, or leaf springs — the rear lift is achieved through the extended shackles working with your factory leaf springs and the new rear shocks.

Yes, when correctly spring-rated for your constant loads, this kit significantly improves towing performance by reducing rear-end sag, maintaining proper suspension geometry, and providing more controlled damping under the dynamic loads of towing. The monotube shock design offers superior heat management during extended highway towing, preventing shock fade that can compromise stability. However, it's critical to select spring rates based only on your constant accessory weight, not towing loads. For optimal towing performance with heavy caravans or variable loads, we strongly recommend adding adjustable airbag suspension to the rear, which allows you to fine-tune support based on actual tongue weight and maintain a level stance regardless of load conditions.

Upper control arm upgrades are not strictly required for this 2-inch lift on the Navara D40, though they become beneficial depending on your specific use case and constant front loads. The factory upper control arms can accommodate this lift height, but if you're running heavy constant front weight (bull bar plus winch plus accessories exceeding 80kg), upgraded control arms with improved ball joint geometry will restore optimal suspension angles and reduce wear on ball joints and CV boots. Extended control arms also provide additional caster adjustment for improved steering feel and high-speed stability. If you frequently drive at highway speeds with heavy front loads or plan to fit 33-inch tyres, control arm upgrades should be considered as part of your complete suspension package for best results.

Yes, a full four-wheel alignment is absolutely mandatory after installing any lift kit, including this Dobinsons Quick-Lift system. The installation process changes suspension geometry, ride height, and component angles, which directly affects camber, caster, and toe settings across both axles. Driving without proper post-installation alignment will result in rapid and uneven tyre wear, poor handling characteristics, reduced braking performance, and potential safety issues. Your alignment technician should reference Nissan D40 specifications and may need to make adjustments to both front and rear settings. We recommend using a suspension specialist or 4WD-experienced alignment shop familiar with lifted vehicles to ensure optimal settings for both on-road manners and off-road capability.

Absolutely — this kit offers multiple load-rated spring options for both front and rear positions, allowing you to precisely match the springs to your Navara's constant accessory weight for optimal ride quality and load-carrying performance. During the ordering process, you'll be prompted to select spring rates based on your current constant load, which includes permanently fitted accessories like bull bars, winches, canopies, drawer systems, dual batteries, and long-range tanks. It's critical to be honest and accurate in your load assessment — selecting springs that are too soft will cause excessive sag and bottoming, while overly stiff springs create a harsh ride and can actually reduce effective load capacity by limiting suspension travel. Calculate your actual fitted accessory weight and select accordingly, remembering that occasional loads like passengers and camping gear should not influence spring selection.

With the 50mm (2-inch) lift provided by this Dobinsons kit, most Navara D40 variants can accommodate tyres up to 32 inches in diameter (265/75R16 or 285/70R17) without significant modifications, though final clearance depends heavily on wheel offset, backspacing, and specific tyre profile. Some light trimming of inner guard plastic and potentially the front mud flaps may be required for full lock-to-lock clearance, particularly with wider tread patterns. If you're planning to run 33-inch tyres or larger, you'll likely need additional modifications including body mount chop, further guard trimming, and potentially diff drop components to maintain CV joint angles within safe operating limits. Always test-fit with your specific wheel/tyre combination and check clearance at full steering lock and full compression before committing to off-road use.

Dobinsons backs this Monotube Quick-Lift Kit with their comprehensive manufacturer warranty covering defects in materials and workmanship, giving you confidence in the quality and durability of your investment. Warranty terms typically cover shock absorbers and struts for a specified period from date of purchase when installed by a qualified technician and used within normal operating parameters. Coil springs are also covered against sagging or breakage under normal use. To maintain warranty validity, it's essential to have the kit professionally installed, maintain service records, avoid overloading beyond rated capacity, and follow the recommended 500km retorque and inspection schedule. Specific warranty duration and terms are provided with your kit — retain your proof of purchase and installation documentation for any future warranty claims.

Yes, this Dobinsons Monotube Quick-Lift Kit is specifically designed to excel in both daily driving and touring applications, not just extreme off-road use. The monotube shock technology provides excellent ride comfort on highways and smooth roads while delivering the damping control needed for corrugated gravel and rough tracks. When correctly spring-rated for your constant loads, you'll experience improved ride quality compared to worn factory suspension, with better control over body roll, reduced nose-dive during braking, and more composed highway manners, especially when loaded. The 2-inch lift height is modest enough to maintain practical step-in height and centre of gravity for daily use while providing meaningful off-road capability improvements. Thousands of Navara owners across Australia use similar Dobinsons setups for daily commuting, work truck duty, and weekend touring without compromise.
