These assembled struts are supplied with Toughdog's standard heavy-duty spring rate, suitable for most D-Max owners carrying typical touring and trade accessories. If you consistently carry significant front-end weight including steel bull bars (30-50kg), heavy-duty winches (30-40kg), dual battery systems, roof racks and rooftop tents, or run consistently heavy payload configurations, contact our team to discuss custom spring rate options. Common front accessories affecting spring selection include aftermarket steel bumpers, winch packages, steel bash plates, upgraded intercoolers, and auxiliary lighting arrays.
Professional installation by a qualified mechanic is strongly recommended to ensure correct fitment, torque specifications and safety compliance. The pre-assembled design significantly reduces installation complexity compared to separate shock and spring kits, with most experienced workshops completing front strut replacement in 2-3 hours. A full four-wheel alignment is mandatory after installation to ensure correct camber, caster and toe settings — preventing premature tyre wear and maintaining steering precision. Allow 500km of varied driving for the foam cell shocks and springs to properly settle and bed in. For maximum performance and geometry correction on lifted D-Max models, consider pairing these struts with upgraded control arms to restore proper ball joint angles and improve suspension articulation.
Toughdog has earned its reputation as Australia's number one 4WD suspension system through decades of proven performance across the harshest touring conditions — from the Simpson Desert to Cape York, the Canning Stock Route to the High Country. Every component is engineered and tested specifically for Australian vehicles, loads and terrain, backed by comprehensive warranty coverage and supported by the largest suspension specialist network in the country. Trusted by professional fleet operators, grey nomad tourers, and weekend adventurers alike, the full Toughdog suspension range delivers the perfect balance of comfort, capability and proven reliability.
These pre-assembled front struts are ideal for D-Max owners seeking a complete, quality-assured suspension upgrade without the complexity of component selection and assembly. Perfect for tradespeople running loaded trays and tool storage, grey nomad tourers carrying campers and towing caravans, weekend adventurers with rooftop tents and touring gear, and families needing improved ride quality with kids and camping equipment. If you regularly carry extreme rear loads or tow heavy caravans, consider complementing this front upgrade with airbag suspension for adjustable rear load support and level towing stance.

These Toughdog assembled front struts are engineered specifically for Isuzu D-Max models manufactured between 2012 and June 2020, covering all SX, LS, LS-M and LS-U variants in both 4x2 and 4x4 configurations. This includes the first-generation D-Max before the 2020 model update. If you have a 2020 D-Max manufactured after June 2020 or a 2021+ model, these struts will not fit as Isuzu introduced significant front suspension changes — you'll need the updated part number for those newer models. The easiest way to confirm exact fitment is to check your VIN plate or contact our team with your build date.
These assembled front struts typically deliver 25-40mm of front lift height depending on your D-Max's current accessory load and factory spring condition. A completely stock, unladen D-Max will achieve closer to 40mm of lift, while vehicles with heavy bull bars, winches and other front accessories will typically see 25-30mm as the stronger springs support the added weight more effectively. This lift range is ideal for leveling the front-to-rear stance (the D-Max sits slightly lower at the front from factory), accommodating larger tyres up to 32-33 inches, and improving approach angles for off-road driving. The lift is progressive and maintains excellent ride quality unlike spacer-based lift methods.
This is a complete pair of ready-to-install front strut assemblies — each unit includes the Toughdog foam cell shock absorber pre-assembled with a heavy-duty coil spring, factory-fitted strut top mount and bearing, protective dust boot, bump stop, and all necessary mounting hardware. Everything arrives assembled to precise specifications, eliminating the need for dangerous spring compression and reducing installation time significantly. You'll need to supply only basic hand tools and workshop equipment for removal and installation. Note that this kit covers front suspension only — if you're building a complete lift system, you'll need to order rear suspension components separately based on your D-Max configuration.
Yes, these Toughdog front struts are engineered to handle the increased front-end loads and stability demands of regular towing up to the D-Max's 3500kg towing capacity. The heavy-duty coil springs and foam cell shock technology provide superior compression control to manage the increased weight transfer during braking and cornering with a loaded trailer. However, remember this kit only addresses front suspension — for optimal towing performance you should also upgrade your rear suspension with matching Toughdog rear shocks and springs, or consider adding airbag suspension for adjustable rear load support and level towing stance. The combination of upgraded front and rear suspension delivers the best towing stability and control.
Upgraded control arms are not mandatory for this lift height range (25-40mm), and most D-Max owners install these struts with factory control arms without issues for typical touring and daily driving use. However, if you're planning to fit larger tyres (32+ inches), undertake serious off-road touring, or want to maximize suspension articulation and geometry correction, aftermarket upper control arms are highly recommended. Extended ball joint control arms restore proper ball joint angles after lifting, reduce stress on CV joints, improve steering geometry, and allow better wheel alignment settings for improved tyre wear and handling. They're particularly worthwhile if you're building a complete long-range touring setup.
Yes, a full four-wheel alignment is absolutely mandatory after installing these assembled struts — it's not optional. Replacing front struts changes your vehicle's ride height and front suspension geometry, which directly affects camber, caster and toe settings. Without proper alignment, you'll experience premature and uneven tyre wear, reduced steering precision, potential pulling to one side, and compromised handling safety. The alignment cost (typically $120-180) should be factored into your installation budget. Make sure to have the alignment performed after the 500km break-in period when the springs have fully settled, or you may need adjustment again as the springs seat themselves under load.
These assembled struts come with Toughdog's standard heavy-duty spring rate which suits most D-Max owners carrying typical touring accessories, bull bars and general payload. If you have specific requirements — such as consistently carrying extreme front-end weight (heavy steel bar, large winch, substantial roof load) or prefer a softer ride for predominantly unladen driving — contact our team before ordering to discuss custom spring rate options. Toughdog manufactures various spring rates to suit different constant load scenarios. It's much easier to specify the correct spring rate at the time of order than to disassemble and change springs later, so take time to honestly assess your typical vehicle load configuration.
With the 25-40mm front lift provided by these struts (combined with appropriate rear lift), most D-Max owners can comfortably fit 32-inch tyres without rubbing or trimming, and some configurations will accommodate 33-inch tyres depending on wheel offset and tyre width. Factory wheel arches and the D-Max's IFS geometry are the primary limiting factors rather than lift height alone. For 33+ inch tyres you'll likely need minor plastic arch trimming and possibly aftermarket upper control arms for clearance at full steering lock and suspension compression. If you're planning significant tyre upgrades, we recommend discussing your complete wheel, tyre and lift package with our team to ensure proper clearances and maintain stable handling characteristics.
Toughdog suspension components are backed by comprehensive manufacturer warranty coverage that protects your investment against defects in materials and workmanship. Specific warranty terms vary by component type — shock absorbers typically carry 2-3 year warranty coverage, while springs are covered for the warranty period applicable to heavy-duty suspension components. Warranty coverage requires professional installation with proof of purchase and proper vehicle application. It's important to note that warranty does not cover damage from incorrect installation, accident damage, modifications, or wear items like bushes and seals that deteriorate through normal use. Keep your purchase receipt and installation records for any warranty claims.
Absolutely — one of Toughdog's key engineering priorities is maintaining excellent unladen ride quality for daily driving while providing the load capacity and control needed for touring and work use. Unlike budget suspension that feels harsh and uncomfortable when empty, these foam cell struts deliver a compliant, controlled ride for city commuting, school runs and highway driving without load. The progressive spring rates and sophisticated shock valving mean the suspension becomes firmer and more controlled as you add weight, rather than riding poorly when empty. Thousands of D-Max owners across Australia use Toughdog suspension for daily driving and weekend adventures with complete satisfaction — you won't sacrifice comfort for capability.
