Isuzu D-MAX Suspension Upgrades Sydney

Suspension Upgrades for Towing, Carrying Loads, and Off-Road Capability

If your Isuzu D-MAX struggles with handling under load or feels unstable when towing, it’s time to upgrade. A suspension upgrade can resolve the floaty feeling when towing trailers and caravans, commonly reported by D-MAX vehicle testers. Our suspension kits deliver better performance, improve weight distribution, and keep your D-MAX safe and compliant.

• Minimise rear sag and improve load levelling, keeping the vehicle level when carrying heavy loads and preventing uneven weight distribution that can negatively impact handling and stability. 
• Reduce sway and maintain vehicle stability at highway speeds.
• Enhance braking performance under load.
• Maintain safe handling and ride comfort even with added accessories.
• Engineered to meet the specific D-MAX requirements of work, towing, and recreational builds

Our suspension kits ensure your D-MAX performs its best for work, towing or off-road adventures.

Enhanced Clearance, Approach and Departure Angles For Your D-MAX

Our suspension upgrades provide added height and protection, enhancing your Isuzu D-MAX’s off-road capability when navigating steep, uneven, or rugged terrain. Perfect for difficult-to-navigate work sites, country driving, or 4WDing around New South Wales.

• Increase ground clearance by 50mm: Gain up to 285mm of clearance, providing better obstacle clearance and off-road capability.
• Improve approach angle from 30° to 32.4°: The 2-inch lift increases the D-MAX’s approach angle by 8%, allowing better access over steep inclines, obstacles, and uneven terrain, reducing the risk of front bumper scraping.
• Improve departure angle from 22–25° to 23.8–27°: The lift improves the departure angle by up to 8%, making it easier to descend obstacles without scraping the rear bumper, especially on steeper declines.
• Protect underbody components in harsh conditions: The increased ground clearance provides added protection for the D-MAX’s diff, exhaust, and transfer case, preventing damage in extreme off-road conditions, especially when tackling rocks, ruts, or uneven tracks.
• Suitable for integration with other upgrades: Our kits are compatible with additional modifications such as recovery gear, heavy-duty suspension, or bash plates, enhancing overall vehicle durability and off-road readiness.
• Optional engineering sign-off for compliance and GVM upgrades: Ensure your D-MAX complies with NSW GVM regulations through an optional engineering sign-off, especially important when carrying heavier loads or towing.

Our kits ensure that your D-MAX performs reliably, even in extreme off-road conditions, by enhancing clearance and angles for tackling tough terrain with confidence.

Suspension Upgrades Tailored to Your Isuzu D-MAX

At Coldys, we don’t sell one-size-fits-all suspension kits. Every suspension upgrade is selected and tuned based on your Isuzu D-MAX’s current setup, intended payload, and application. Our suspension kits are suited to RG-series D-MAX models (2020–present) with independent front suspension and rear leaf springs.

• Rear leaf spring options rated for 0–660 lb (0–300 kg) constant loads — ideal for utes with canopies, drawer systems, or trade trays.
• Front coils matched to support bull bars, dual battery setups, winches, and other heavy accessories, while minimising front-end sag.
• Delivers up to 2 inches (50mm) of clearance to improve approach angles and underbody protection in off-road or worksite conditions.
• Our suspension kits are designed to maintain proper steering geometry, addressing concerns related to 'bump steer' and uneven tyre wear.
• We ensure all components are professionally installed and aligned to prevent issues such as rear spring sagging or driveline vibrations, especially after lifting.

At Coldys, we ensure all components are professionally installed and aligned to maintain long-term durability, ride quality, and handling — no shortcuts.

Upgrading your vehicle’s suspension can affect its Gross Vehicle Mass (GVM), especially if you tow or carry heavy loads. It’s important to ensure compliance with GVM regulations in New South Wales for legal and insurance purposes. For more details on GVM requirements, visit the Service NSW Vehicle Safety Compliance Certification Scheme page. If you need assistance, we can help determine how your upgrades may impact your vehicle’s GVM. See our Isuzu D-MAX GVM upgrades.

Frequently Asked Questions

Do I need a suspension upgrade to tow a caravan?

If you're towing a caravan, a suspension upgrade is often essential to manage the extra weight and maintain safe handling. It helps reduce rear sag, improves braking, and enhances overall stability when under load. It’s also important to check your vehicle’s Gross Vehicle Mass (GVM) and ensure that the combined weight of passengers, cargo, accessories, and tow ball load does not exceed legal limits. If you're nearing or exceeding your GVM, an upgrade may be required to stay compliant — and at Coldys, GVM upgrades are available to help you tow safely and legally.

How much does an Isuzu D-MAX suspension upgrade cost?

Costs vary depending on the vehicle, load requirements, and whether certification is needed. Most suspension upgrade installations cost between $924 - $1200. Contact us for a tailored quote for your vehicle.

How long does a suspension upgrade take?

At Coldys, we have some of the best installation lead times in the industry, with most suspension upgrades completed in a single day. We'll confirm lead times when you book.

Do I need a wheel alignment after a suspension upgrade?

Yes. We include or recommend a wheel alignment to protect tyre wear and maintain proper handling after your suspension upgrade.

What are the vehicle suspension upgrade laws in NSW?

In NSW, you can raise your vehicle’s ride height by up to 2 inches (50mm) through suspension changes without needing certification. A total lift of up to 3 inches (75mm) is allowed if part of that increase comes from larger tyres (e.g. 2 inches from suspension and 1 inch from tyres). Certification is required for lifts beyond these limits, for any body lift, or if you alter the suspension design (e.g. changing coil to leaf springs). Non-compliance can lead to fines or registration being cancelled. See full details here: RMS Suspension and Ride Height Info

If I Want To Fit A Bullbar, Do I Need To Upgrade D-Max Suspension?

Fitting a bull bar to your Isuzu D-MAX may not require a suspension upgrade, but adding weight, especially with a winch or heavy accessories, can affect handling and ride quality. If you’re adding significant weight, upgrading the suspension helps maintain proper stance, improves performance, and protects against underbody scraping. Bull bars add 90-150 kg to the front of the vehicle.

• A suspension upgrade is recommended with a winch or heavy gear.
• Upgrading ensures compliance with GVM limits and maintains vehicle performance.

What Is The Maximum Load I Can Carry On A D-Max Roof Rack? Will This Affect Handling?

The maximum load you can carry on a D-MAX roof rack typically ranges from 100 to 150 kg, depending on the type of roof rack and vehicle model. Carrying a heavy load on the roof can affect handling, as it raises the vehicle's centre of gravity, potentially reducing stability, increasing body roll, and making the vehicle more prone to tipping in extreme conditions. For optimal safety and handling, it’s important to evenly distribute the load and avoid exceeding the weight limit.

If you're unsure about the exact weight capacity, we will help determine the safe load for your specific setup.
