A damper-and-spring kit replaces the vehicle's factory shock absorbers and coil springs as a matched set. It changes ride height, how the suspension controls body movement, and how the car carries load—but it does not add wheel travel by itself, and it is not a bolt-on-and-forget modification. Choose the kit only after confirming the exact vehicle variant, the real lift height, and who will install and align it.
The current Decision Maker 4X4 listing offers the TEIN 4X4 Damper Sport suspension kit with two selectable variants—Tank 300 and Tank 500. The written listing confirms the product identity, the variant split and the headline features (adjustable damping force, TEIN's Hydraulic Bump Stopper design and integrated damper construction), and it describes an approximate 1.5-inch lift as shown in the source gallery. It does not state spring rates, damper lengths, or a model-year breakdown. Those gaps are exactly what the eight checks below are for.

What a damper-and-spring kit does—and does not do
Springs carry the vehicle's weight and set ride height; dampers control how fast the suspension moves. Replacing both as a matched kit is the coherent way to lift a vehicle mildly and keep the damping in sync with the new spring rates. The listing's feature artwork highlights adjustable damping (a dial changes damping force), a hydraulic bump stopper design for the end of travel, and an integrated damper body—features aimed at mixed road and off-road use.
What a kit like this does not do: it does not increase wheel articulation on its own, it does not correct geometry worn elsewhere, and it does not make the vehicle immune to bottoming or body roll. A roughly 1.5-inch lift also raises the centre of gravity slightly and changes headlight aim, sensor heights and sometimes wheel alignment tolerances—which is why the checks below matter more than the feature list.
On a phone: swipe the table sideways to see all columns.
| Goal | What a matched damper-and-spring kit can help with | What it does not change |
|---|---|---|
| Mild lift for clearance and tyre room | Raises static ride height by the kit's designed amount | Does not add suspension travel or articulation by itself |
| Corrugated roads and touring load | Fresh dampers with adjustable force can be tuned to load and surface | Does not fix worn bushes, ball joints or bent components |
| Heavy constant accessories (bar, winch, drawer systems) | A matched spring rate can carry constant load better than tired factory springs | The listing does not state spring rates—confirm them before assuming load capacity |
What the current TEIN Damper Sport listing includes
The live TEIN 4X4 Damper Sport Suspension Kit for GWM Tank 300 / 500 is sold as one vehicle-specific package with a required variant choice: Tank 300 or Tank 500. The listing describes the package as the matching front and rear dampers and springs for the selected model, and its feature artwork states adjustable damping force, TEIN's Hydraulic Bump Stopper (H.B.S.) design and integrated damper construction.
TEIN is an established Japanese suspension manufacturer, and the 4X4 Damper Sport is its lift-oriented line for body-on-frame 4WDs. That lineage is a genuine point in this kit's favour—but it does not remove the need to verify this specific listing. The written product record reviewed for this article does not state spring rates, damper body dimensions, adjustment-click counts, or a model-year and powertrain breakdown beyond the Tank 300 / Tank 500 variant selector, and the approximately 1.5-inch lift figure is described as shown in the source gallery rather than as a measured specification. Confirm all of these in writing for your exact vehicle before ordering.
Eight checks before buying a suspension kit
1. Lock the exact variant before anything else
This listing covers two different vehicles. The Tank 300 and Tank 500 differ in weight, suspension pickup points and geometry, so the kits are not interchangeable. Select the variant that matches your vehicle, and if your car is a Hybrid or PHEV version, say so explicitly when confirming fitment—battery and drivetrain weight can change what the correct spring and damper setup looks like.
2. Treat the lift figure as approximate until confirmed
The listing describes an approximate 1.5-inch lift as shown in the source gallery. Actual ride-height change depends on your vehicle's current condition, its load and how the new springs settle. Ask for the figure in writing, and measure your own hub-to-guard heights before and after installation so you know what actually changed.
3. Ask for spring rates—and match them to your real load
Spring rate decides whether a lifted car rides beautifully or crashes over bumps. The listing does not publish rates, so ask: what are the front and rear rates, and what constant accessory weight do they assume? If you run a bull bar, winch, dual battery or drawer system, name them. A kit tuned for an empty car can sit nose-low or ride harsh once your real accessories are on.
4. Budget for a wheel alignment—it's not optional
Any ride-height change alters camber, caster and toe. Driving on fresh suspension without an alignment wears tyres quickly and can make the car wander. Book the alignment with the installation, and mention the lift to the alignment shop so they work to the right targets. If the vehicle has driver-assistance sensors or cameras calibrated to a factory height, ask whether recalibration is needed on your model year.
5. Understand what installation actually involves
Suspension work means spring compressors under load, high torque values and components that can injure if handled casually. This is workshop work for most owners: a hoist, the right tools and experience with strut assemblies. If you are quoting the job, confirm whether the price includes the alignment and a post-installation re-check, not just the bolt-on labour.
6. Think through warranty and insurance before modifying
A suspension kit is a significant modification. It can affect how a manufacturer assesses a related warranty claim, and your insurer may require disclosure. Rules for lifted vehicles and certification requirements vary between Australian states and territories. Tell your insurer before the install, keep the invoice and install records, and check the current factory specifications for your vehicle on GWM Australia's Tank 300 page so you know the baseline you are modifying from.
7. Plan how you will dial in the damping
Adjustable damping is only useful if you actually adjust it. Start at the manufacturer's suggested middle setting, drive your usual mix of road and track, then adjust in small steps—softer for corrugations, firmer for highway load—and note what you changed. Avoid the temptation to set maximum stiffness and leave it; that is how good dampers get blamed for a bad setup.
8. Schedule the post-installation checks
New springs settle. Re-check ride height and fastener torque after the first few hundred kilometres, inspect the dampers for weeping after the first rough trip, and re-check alignment if the height moved as the springs settled. Suspension is a system: the kit, the alignment and the follow-up are one job, not three separate ones.
Which setup suits your Tank?
For a daily-driven Tank 300 or 500 that sees weekend gravel, a mild lift with adjustable damping is the flexible option—comfortable on-road, tunable for load. For a dedicated touring build, treat suspension as the foundation it is: tyres, pressures and protection all interact with it. Our tyre deflator guide and tyre inflator guide cover the tyre-side workflow that pairs with a lifted touring car, and the Tank 300 accessories collection groups the protection and storage categories in one place.
One honest caution: if the vehicle is still under factory warranty and mostly commutes, weigh the modification carefully. A suspension kit is the kind of change that is easy to buy and slow to undo.
Australian context and factory specifications
Factory ride heights, suspension specifications and towing or load ratings are published by the manufacturer and can change between model years and powertrains. Use GWM Australia's current specifications as the baseline, and treat any aftermarket listing—including this one—as product information, not a vehicle rating. Modification and certification rules sit with state and territory authorities; if your lift or tyres will be significant, check whether your state requires certification or inspection for the change.
Send the details that make a fitment answer useful
Send your Tank model, year, powertrain (petrol, diesel, HEV or PHEV), current suspension condition, and the constant accessories you carry—bull bar, winch, battery, drawers, roof load. Include your hub-to-guard ride heights if you can measure them.
Ask us to confirm the correct variant, package contents, spring rates, stated lift and the exact delivered price for your selected option before ordering. Redact registration plates and personal information from photographs where practical.
Ask about suspension fitmentFrequently asked questions
Does one kit fit both the Tank 300 and Tank 500?
No. The listing sells two separate vehicle-specific variants under one product page. Select the variant for your vehicle and confirm fitment in writing before ordering—do not assume shared parts across the two models.
How much lift does the kit give?
The listing describes an approximate 1.5-inch lift as shown in the source gallery. Treat that as approximate until confirmed in writing, and measure your own vehicle before and after installation to know the real change.
Is the kit suitable for a Hybrid or PHEV Tank?
The listing offers Tank 300 and Tank 500 variants without a powertrain breakdown. Hybrid and PHEV versions carry different weight, so confirm your exact powertrain with the store before ordering.
Do I need a wheel alignment after installing?
Yes. Any ride-height change alters alignment angles. Book the alignment with the installation, and re-check it once the new springs have settled.
Will this fix a sagging or harsh factory ride?
Fresh matched dampers and springs often improve ride control, but a kit cannot repair worn bushes, ball joints or bent components elsewhere. If the car rides badly now, diagnose the whole suspension before assuming new parts will solve it.
Evidence boundary: the linked Decision Maker 4X4 listing and photographs support the product identity, the Tank 300 / Tank 500 variant split, and the listing's stated features (adjustable damping force, H.B.S. design, integrated construction, approximate 1.5-inch lift as shown in the source gallery). These are reproduced as listing statements, not independent measurements or test results. The listing does not state spring rates, dimensions or adjustment-click counts. GWM Australia's website is the primary source for factory vehicle specifications. No independent fitment, performance or compliance test is claimed.
