Choose your rear spring rate based on what stays fitted to the vehicle day to day, not just what you carry occasionally. A tow bar, second battery tray, drawer system, water tank or bull bar all add constant weight that a factory spring wasn't designed to carry, which is what causes rear-end sag over time. If your WK2 regularly tows a caravan or box trailer, or runs a canopy and drawers for work, tell our team what's fitted and we'll confirm the heavy-duty rate suits your load before you order.
Fitting rear coil springs on a WK2 is a suspension job best handled by an experienced installer or a workshop with a spring compressor, given the load the rear springs carry under compression. A wheel alignment is mandatory after fitting to bring camber, caster and toe back within factory tolerance. Allow around 500km for the springs to settle into their working height before judging final ride height. If you're also addressing worn bushes or geometry issues, pair the springs with our control arm upgrades for a complete rear-end refresh.
Toughdog has been developing suspension for Australian conditions for decades, with springs and shocks tuned for the load-carrying and touring demands specific to this market. Every Toughdog coil spring is backed by a manufacturer warranty and matched to a shock absorber range engineered around the same spring rates. It's a brand tradespeople and tourers reach for when factory suspension isn't holding up to constant load — view the full Toughdog range for matched shocks and front springs.
This spring pair suits WK2 owners running a tow bar and caravan, tradies with a canopy and drawer system, or anyone whose rear end sits low from constant load. If your load varies significantly — for example towing some weekends and running empty the rest of the week — our airbag suspension range is worth comparing, since it lets you adjust support to match the load on the day.
These Toughdog rear coil springs are in stock in Australia now for fast dispatch, with our team on hand to confirm the right spring rate for your WK2's accessory load before you buy. Browse our full lift kit range if you're planning a bigger suspension upgrade alongside these springs.

Yes, this pair is designed specifically for the WK2 Grand Cherokee built from 2011 to 2021, covering the 3.0L CRD diesel, 3.6L Pentastar petrol and 5.7L HEMI variants. Fitment is to the factory rear spring perches with no cutting or drilling required. If you're unsure of your exact build, use our parts finder for the Grand Cherokee WK2 or contact our team with your VIN.
These are heavy-duty replacement springs, not an aftermarket lift kit, so the main job they do is restore correct factory ride height once it has sagged from constant load. They are matched to a heavier rate than the standard spring rather than built to raise the vehicle beyond its original height. If you want additional lift as well as load support, ask our team about pairing these with a front and rear lift kit option.
You get two Toughdog heavy-duty rear coil springs, one for each side, with a corrosion-resistant coating and fitment instructions. Front springs, shock absorbers and control arms are not included and are sold separately. This keeps the kit focused on rear spring replacement, which is the usual point of failure when a WK2 sags under constant load.
Yes, the heavy-duty rate is specifically intended for vehicles carrying constant load such as a tow bar, caravan hookup or loaded canopy. It's built to hold correct ride height and geometry while towing, rather than sagging like a factory spring under the same load. Tell our team your typical tow ball weight and we can confirm this rate is the right match before you order.
Not necessarily for a straight spring replacement at standard ride height, since these springs are matched to work with the factory rear geometry. If you're also adding a lift kit or notice worn bushes during fitment, our control arm range is worth checking to keep rear geometry correct. Our fitment team can advise based on your specific setup and any other suspension changes planned.
Yes, a wheel alignment is mandatory after fitting new rear coil springs on any WK2. Ride height and axle position change slightly with new springs, which affects camber, caster and toe. Skipping alignment leads to uneven tyre wear and can affect handling stability, so book it in straight after installation.
Toughdog produces coil springs across a range of rates for the WK2 to suit different accessory loads. This listing is the heavy-duty rate, aimed at vehicles carrying tow bars, drawer systems or similar constant weight. If your load is lighter or heavier than that, contact our team with details of what's fitted to your vehicle and we'll confirm the best rate for you.
These springs are designed to restore correct ride height rather than significantly raise the vehicle, so don't expect extra clearance for larger tyres from this product alone. Tyre clearance depends more on wheel offset, tyre width and any lift kit fitted. If bigger tyres are the goal, talk to us about combining these springs with a front and rear lift kit.
These springs are covered by Toughdog's manufacturer warranty against manufacturing defects. Full warranty terms and conditions are confirmed at the time of purchase and are available from our team on request. We also provide fitment support if you have questions before or after installation.
Yes, the heavy-duty rate is tuned to carry constant load without turning the rear end harsh on a daily commute. It's matched to work with factory or upgraded rear shocks to keep ride quality reasonable when the vehicle is both loaded and unloaded. Most WK2 owners fitting these run them as their everyday rear spring, not just for occasional towing trips.
