The adjustable design allows you to optimize damping for your specific use case. Soften settings for empty, unladen driving to maximize comfort and road compliance. Firm up settings when carrying heavy loads, towing caravans, or tackling corrugated outback tracks to maintain control and reduce body movement. The external adjuster is accessible with the shock installed, making real-world tuning quick and convenient. Start at mid-range settings and fine-tune based on load weight, towing requirements, and personal preference — you'll find the sweet spot within a few adjustments.
Professional installation by a qualified mechanic or experienced DIY installer is recommended for optimal results and safety compliance. Installation involves removing factory rear shocks and fitting the Toughdog adjustable units using existing mounting points — typically completed in 1-2 hours. While wheel alignment is not strictly mandatory for rear shock replacement alone, a full alignment check is highly recommended if you're also installing lift kits or suspension components. Allow a 500km break-in period for seals and bushes to settle before finalizing your adjustment preferences.

Yes, these Toughdog rear adjustable shocks (SKU 6071) are specifically engineered for Isuzu D-Max models from 2008 to 2012 (RC series, first generation). They're designed to bolt directly to factory mounting points on both 4x2 and 4x4 variants with the 3.0L turbo diesel engine. The shocks suit both factory-height and lifted D-Max utes, providing compatibility across a range of suspension configurations. If you've modified your vehicle extensively or are unsure about fitment with your specific setup, our technical team can confirm compatibility before you order.
These Toughdog shocks feature external adjustable damping that you can change without removing the shock from the vehicle. The adjuster is typically accessible from under the vehicle or through the tray/tub, depending on your D-Max configuration. You can rotate the adjuster through multiple positions — usually 8-12 clicks from softest to firmest — allowing you to fine-tune compression and rebound damping. Softer settings suit unladen driving for maximum comfort, while firmer settings provide better control when loaded or towing. The adjustment takes just minutes and can be changed as often as your load requirements change.
This kit includes a matched pair (left and right) of Toughdog rear adjustable shock absorbers designed for the 2008-2012 Isuzu D-Max. The shocks come with mounting bushes and necessary hardware for installation. Installation instructions and an adjustment guide are included to help you optimize settings for your specific use. Please note this is a rear shock pair only — front shocks, springs, U-bolts, and other suspension components are sold separately. If you're building a complete suspension upgrade, we can help you select compatible components for your D-Max.
Absolutely — these adjustable shocks are excellent for towing applications on the Isuzu D-Max. The ability to firm up the damping when towing provides better load control, reduced body pitch and squat, and improved stability at highway speeds. When towing heavy caravans or trailers, you'll benefit from dialing the shocks to a firmer setting to counteract the additional rear weight and maintain vehicle composure. For maximum towing performance and leveling capability, consider pairing these shocks with upgraded rear leaf springs or an airbag suspension system. The adjustability means you can return to softer, more comfortable settings when driving unladen.
Control arm upgrades are not required when fitting these rear adjustable shocks to a factory-height or moderately lifted D-Max. These shocks are designed to work with your existing suspension geometry and mounting points. However, if you're installing a significant lift kit (50mm+), or if your factory control arms and bushes are worn, upgrading to heavy-duty control arms can improve suspension articulation, correct geometry, and enhance overall durability. Control arms become more important for front suspension modifications on the D-Max. Our team can advise on the best combination of components based on your intended lift height and use case.
A wheel alignment is not strictly mandatory when replacing rear shocks only, as you're not altering suspension geometry or ride height significantly. However, it's good practice to have your alignment checked, especially if you're also installing springs, lift kits, or other suspension components at the same time. Proper alignment ensures even tire wear, optimal handling, and prevents premature component wear. If you notice uneven tire wear or steering pull after installation, a four-wheel alignment is recommended. Most professional installers will suggest an alignment check as part of any major suspension work to ensure everything is set correctly.
These Toughdog rear adjustable shocks are supplied with a pre-set spring rate and valving optimized for the Isuzu D-Max 2008-2012 platform. While you cannot change the internal spring rate, the external adjustability allows you to modify damping characteristics across a wide range — effectively giving you multiple shock personalities in one unit. This adjustability covers the needs of most users from unladen comfort to heavily loaded control. If you require significantly different spring rates for extreme load carrying, you would need to upgrade your rear leaf springs separately. The shock adjustability then allows you to fine-tune damping to match your chosen spring rate perfectly.
These rear shocks alone do not provide additional lift height — they're designed to work at or near factory ride height (or with existing lifted applications). If you want to fit larger tyres, you'll need to install a complete lift kit that includes front and rear springs or suspension components to raise the vehicle and provide clearance. Typically, a 50mm lift allows 32-inch tyres on a D-Max, while a 75mm+ lift can accommodate 33-inch tyres, depending on wheel offset and other modifications. These adjustable shocks can be specified as part of a complete Toughdog lift kit to ensure all components work together perfectly. Check our lift kit range or contact us for advice on achieving your desired tyre clearance.
Toughdog suspension products are backed by a comprehensive manufacturer warranty that covers defects in materials and workmanship. Warranty terms typically range from 12 months to lifetime on certain components, depending on the specific product line and application. These rear adjustable shocks carry Toughdog's standard warranty protection, giving you peace of mind for your investment. Warranty coverage requires professional installation and normal use conditions. For specific warranty terms, duration, and claim procedures for this product, please contact us directly or refer to the warranty documentation included with your shocks. We're here to support you throughout the life of your suspension system.
Yes, these Toughdog adjustable shocks are excellent for daily driving and provide a comfortable, controlled ride on sealed roads. When adjusted to softer settings for unladen driving, they deliver a compliant, smooth ride quality that's ideal for commuting and highway touring. The multi-stage valving ensures they remain composed over bumps and road imperfections without harshness. You can firm them up when carrying loads or towing, then return to softer settings for everyday comfort. This versatility makes them perfect for D-Max owners who use their vehicle as both a workhorse and family transport. The adjustability ensures you're never stuck with a compromise — you get comfort when you want it and control when you need it.
Proper upgrade for a working truck
Had these Toughdog adjustable shocks fitted to my 2010 D-Max about three months back and they've made a massive difference, especially when I'm loaded up with tools and materials during the week. The adjustability is dead simple to dial in depending on whether I'm running empty or towing the work trailer, and they've handled some rough bush tracks on weekend camping trips without any dramas. Well worth the money for a daily driver that actually earns its keep.(5)
Proper Kit for Remote Outback Work
Been running these Toughdog adjustable rears on my D-Max through the Simpson Desert and Cape York, and they've completely transformed how the truck handles corrugations with a loaded canopy. The ability to dial them up when I'm carrying water and recovery gear, then soften them off for the highway run home, is exactly what remote touring demands. Fitment was spot-on and they've stayed leak-free through some seriously punishing tracks.(5)
Perfect for Loaded Touring and Towing
These adjustable shocks have completely transformed how our D-Max handles when we're loaded up with camping gear and towing the camper trailer down to the coast. Being able to dial in the firmness depending on whether we're empty or fully loaded is a game changer - no more wallowing around corners with the van on the back. The build quality feels solid and they've held up brilliantly through some pretty rough corrugated tracks up in the High Country.(5)
