Not sure if this fits your vehicle or which spring rate to select? Contact our suspension experts for personalised advice or check our FAQ page for detailed fitment information.
Selecting the correct spring rate is critical for achieving optimal ride quality and preventing premature wear on suspension components. Your spring choice should be based on your constant accessory load — the weight permanently installed on your vehicle, not occasional or temporary loads. Common front-end accessories affecting spring selection include bull bars (20-40kg), winches (30-50kg), upgraded steel bumpers, driving lights, UHF aerials, long-range fuel tanks, and aftermarket air conditioning systems. Occasional loads such as camping gear, passengers, or towing loads should not influence your spring rate choice as this will result in an excessively firm ride when unladen. When in doubt, consult our spring rate selection chart provided with your kit or contact our team for load assessment assistance.
Professional installation by a qualified mechanic or experienced 4WD workshop is strongly recommended for these assembled struts to ensure correct fitting, torque specifications, and safety. Wheel alignment is mandatory following installation to restore factory caster and camber settings, prevent uneven tyre wear, and maintain proper steering response. A 500-kilometre break-in period is required for springs to settle and damper seals to properly bed in — ride height and handling characteristics will optimise during this period. For D40 Navara owners adding significant lift or running larger tyres, we recommend pairing these struts with upgraded control arms to correct ball joint angles and maximise suspension travel.
Toughdog has earned its reputation as Australia's number one 4WD suspension brand through decades of outback-proven reliability, Australian engineering expertise, and unwavering commitment to performance and value. Every Toughdog product is tested across the harshest Australian conditions and backed by comprehensive warranty coverage. Trusted by recreational tourers, professional tradespeople, emergency services, and mining operations nationwide, the complete Toughdog suspension range delivers consistent quality that Australian 4WD owners depend on when far from help.
These assembled struts are ideal for Nissan D40 Navara owners seeking hassle-free suspension upgrades — from weekend warriors and touring families to tradespeople requiring reliable load-carrying capability. Recreational tourers will appreciate the balanced on-road comfort and off-road performance, while tradespeople benefit from consistent front-end support for tools and equipment. Caravan towers and those carrying heavy constant loads should also consider supplementing with airbag suspension at the rear for optimal load distribution and ride height adjustment capability.

These Toughdog front assembled struts are engineered specifically for Nissan D40 Navara models from 2005 to 2015, including all variants such as King Cab, Dual Cab, ST, ST-X, and RX configurations. They're compatible with both Spanish and Thai-built D40 models across all engine options including the 2.5L YD25 turbo diesel, 3.0L V6 diesel, and 4.0L V6 petrol. The struts are designed as direct replacements for factory front suspension components and fit all standard mounting points without modification. If you're unsure about your specific variant or have aftermarket modifications, our technical team can confirm exact fitment for your vehicle.
These assembled struts are designed primarily to restore or maintain factory ride height while providing superior load-carrying capacity and performance compared to standard replacement shocks. Depending on the spring rate selected and your vehicle's current condition, you may experience 0-25mm of lift over worn factory suspension. The primary benefit is preventing front-end sag from accessories like bull bars and winches rather than dramatic height increase. For significant lift height on your D40 Navara, consider a complete lift kit package that includes matched rear suspension components for balanced geometry and performance.
This package includes a pair (2 units) of fully assembled Toughdog front struts with foam cell shock absorbers pre-installed with matched heavy-duty coil springs. Each assembly includes spring isolators, protective components, and mounting hardware necessary for installation. The pre-assembled design means you receive a complete, ready-to-install unit that significantly reduces installation time compared to purchasing shocks and springs separately. Upper strut mounts and top hats are typically reused from your existing vehicle components, though replacement mounts are available separately if your originals show wear or damage.
Yes, these Toughdog assembled struts are engineered to handle the increased front-end loads associated with towing, particularly the tongue weight transferred through the vehicle when a trailer or caravan is connected. The upgraded foam cell damping and heavy-duty spring options provide superior control and prevent excessive nose-dive during braking compared to worn factory suspension. However, it's important to select the appropriate spring rate based on your constant front accessory load, not occasional towing loads. For optimal towing performance and rear load support, consider pairing these front struts with upgraded rear suspension or airbag assistance systems.
Control arm upgrades are not mandatory for fitting these assembled struts if you're maintaining near-factory ride height, as the geometry changes are minimal. However, if you're combining these struts with rear lift components to achieve overall vehicle lift, or planning to run significantly larger tyres, upgraded control arms become highly recommended. Aftermarket control arms correct ball joint angles, restore proper CV axle geometry, increase suspension travel, and often include improved bushings for enhanced durability. For D40 Navara owners pursuing maximum capability and lift, control arms are a worthwhile investment that complements the performance benefits of these Toughdog struts.
Yes, professional wheel alignment is absolutely mandatory after installing these or any replacement front suspension components on your D40 Navara. Even though these are direct replacements, the installation process involves disconnecting steering and suspension components that affect alignment settings. Proper alignment ensures correct caster, camber, and toe settings which are critical for safe steering response, optimal tyre wear, and vehicle stability. Skipping alignment can result in rapid tyre wear, poor handling characteristics, and potentially dangerous steering behaviour. Plan for alignment costs and scheduling when budgeting for your suspension upgrade.
Absolutely — Toughdog offers multiple spring rate options specifically to accommodate varying front accessory loads on D40 Navara vehicles. When ordering, you'll select your spring rate based on your constant accessory weight, which includes permanently installed items like bull bars, winches, upgraded bumpers, and additional lighting systems. It's critical to select based only on constant loads, not occasional cargo or towing weights, as over-springing results in harsh ride quality and potential damage to other suspension components. Our team can help calculate your accessory weight and recommend the optimal spring rate, or you can use the selection chart included with detailed weight guidelines for common D40 accessories.
These assembled struts primarily restore factory ride height and prevent accessory sag rather than providing significant lift for larger tyres. While you may gain 0-25mm of front height depending on your vehicle's current condition and spring choice, this alone won't substantially increase tyre clearance. Most D40 Navara owners require body lifts, diff drops, or comprehensive suspension lift packages to accommodate tyres significantly larger than factory specifications. That said, the improved suspension travel and damping control from these Toughdog struts will enhance performance regardless of tyre size. Contact our team to discuss your specific tyre size goals and we can recommend the complete suspension package needed to achieve safe clearance.
Toughdog backs these assembled struts with their comprehensive manufacturer warranty covering defects in materials and workmanship, reflecting their confidence in Australian engineering and quality control. Specific warranty terms and duration are provided with your purchase documentation and may vary based on application and usage conditions. To maintain warranty validity, professional installation is recommended with records retained, and the product must be used within its designed specifications and load ratings. Toughdog's strong reputation in the Australian market is built on standing behind their products, and warranty claims are processed through authorised dealers with genuine replacement components.
Yes, these Toughdog assembled struts are engineered to deliver excellent daily driving comfort while maintaining the capability for weekend adventures and off-road excursions. The foam cell damping technology provides progressive resistance that absorbs corrugations and bumps more effectively than standard gas shocks, reducing harshness transmitted to the cabin. Toughdog's valve tuning is specifically designed for the Australian market, balancing comfortable highway cruising with controlled performance on gravel roads and tracks. Many D40 Navara owners report noticeably improved ride quality compared to worn factory suspension, particularly when the correct spring rate is selected for their accessory load, making these struts ideal for vehicles serving dual-purpose roles as daily drivers and touring rigs.

Well worth the money for a pre-assembled setup that just bolts straight in.(5)
Proper Kit for Remote Touring
Been running these assembled struts on my D40 through the Canning Stock Route and countless Cape York trips. The pre-assembled setup saved me a full day of mucking around, and they've handled corrugations and creek crossings without missing a beat. Ride quality is noticeably better than stock, especially when loaded up with recovery gear and long-range tanks. Toughdog's clearly designed these with actual Australian conditions in mind.(5)
Perfect Upgrade for Our Family Tourer
Fitted these assembled struts to our D40 about three months back and they've completely transformed how the Navara handles with the camper trailer and all the kids' gear loaded up. The ride quality is noticeably smoother on corrugated roads, and my wife even commented on how much more comfortable the drive to our usual Cape York spot was. Being pre-assembled saved me hours in the shed, and the Australian build quality really shows – they're handling everything we throw at them.(5)
