Selecting the correct spring rate is critical for optimal performance and ride quality. Your spring rate choice should be based on your constant load only - this means accessories and equipment permanently installed in your vehicle. Common rear constant loads include cargo barriers, storage drawers, dual battery systems, fridges, water tanks, second spare tyres, roof racks with accessories, canopies or hard lids, and permanently mounted recovery equipment. Do not factor in occasional loads like passengers, camping gear, or firewood, as selecting too heavy a spring rate will result in harsh ride quality and potential damage to other suspension components. If you regularly tow a caravan or trailer but don't always have it attached, consider airbag suspension as a more versatile solution that adjusts for variable loads.
Professional installation by a qualified mechanic is strongly recommended for coil spring replacement due to the significant forces involved and specialized spring compressor tools required. Wheel alignment must be performed after installation to ensure proper tracking and tire wear patterns. Allow a 500km break-in period for springs to settle and reach their final ride height - some initial settling is normal. For WK2 Grand Cherokees carrying heavy constant loads or running larger than stock tyres, consider pairing these springs with upgraded control arms to maintain optimal suspension geometry and improve handling characteristics.
Toughdog is Australia's most trusted 4WD suspension brand with over three decades of experience engineering suspension solutions for Australian conditions.

Trusted by tradespeople, touring families, and serious four-wheel drivers, the complete Toughdog suspension range delivers exceptional durability backed by comprehensive warranty coverage and unmatched Australian support.
These rear coil springs are ideal for Jeep Grand Cherokee WK2 owners who have added permanent accessories causing rear sag, tourers carrying camping equipment and recovery gear, families with roof pods and cargo systems, or anyone experiencing reduced ride quality from worn factory springs. If you tow caravans or heavy trailers frequently, consider complementing these springs with airbag suspension for adjustable load support that adapts to towing and unladen driving conditions.

Yes, these Toughdog rear coil springs are specifically engineered for the Jeep Grand Cherokee WK2 series manufactured from 2010 to 2021, covering all engine variants including petrol and diesel models. The springs are designed as direct replacements for the factory rear coils using existing mounting points without any modifications required. To confirm fitment for your specific build date and variant, use our online parts finder or contact our team with your VIN number. These springs are sold as a pair for both rear positions.
These Toughdog rear coil springs are primarily designed to restore factory ride height and support constant loads rather than provide significant lift. Depending on your selected spring rate and current rear sag, you may see 0-25mm of height restoration compared to worn factory springs. The actual height achieved depends on your constant load weight - heavier spring rates supporting more weight will sit lower when unladen, while lighter rates will sit higher but support less weight. The goal is proper ride height under your typical loaded condition, not maximum lift.
This kit includes a pair (2 springs) of Toughdog heavy-duty rear coil springs specifically engineered for the Jeep Grand Cherokee WK2 platform. The springs feature high-tensile spring steel construction with corrosion-resistant powder coating. This is a springs-only kit - you will need to reuse your existing spring seats, isolators, and mounting hardware. Shock absorbers are not included and are sold separately if upgrades are required. Front coil springs are also sold separately if you need a complete front and rear spring package.
Yes, when you select the appropriate spring rate for your constant load, these Toughdog springs improve towing performance by reducing rear squat and maintaining proper suspension geometry. Firmer spring rates help prevent the rear from sagging when towing caravans or trailers, which improves brake effectiveness, steering control, and headlight aim. However, remember that your towed load should not be factored into spring rate selection - only permanent accessories count as constant load. For maximum towing versatility with adjustable support, consider adding airbag suspension which can be inflated when towing and deflated for unladen comfort.
Control arm upgrades are not mandatory when fitting these rear coil springs if you're maintaining near-factory ride height, but they can be beneficial depending on your setup. If you're carrying heavy constant loads, running larger tyres, or have significant wear in your existing control arm bushes, upgraded control arms improve handling, reduce bushing deflection, and maintain better suspension geometry. For Grand Cherokees used for serious touring or off-road work, pairing these springs with quality aftermarket control arms optimizes the entire suspension system. Our team can recommend whether control arm upgrades suit your specific application.
Yes, a full four-wheel alignment is mandatory after installing new rear coil springs on your Grand Cherokee WK2. Changing rear spring height affects your vehicle's ride height, which alters suspension geometry and can shift alignment angles including camber, toe, and thrust angle. Without proper alignment after spring installation, you'll experience uneven tyre wear, poor handling characteristics, and potentially reduced fuel economy. Make sure your installer performs a comprehensive alignment check and adjustment as part of the spring replacement process. Most professional workshops include this as standard practice.
Spring rate selection is based exclusively on your constant load - permanently installed accessories that your vehicle carries all the time. Calculate the total weight of rear accessories including cargo barriers, drawers, dual batteries, fridges, water tanks, additional spare tyres, canopies, and roof rack systems with permanently mounted equipment. Do not include occasional loads like passengers, camping gear, or towing weight when selecting spring rates. If you're unsure about your constant load weight, our suspension experts can help you calculate and recommend the appropriate spring rate. Selecting a spring rate that's too heavy will result in harsh ride quality and potential component damage.
These rear coil springs are designed to restore factory ride height rather than provide significant lift, so tyre clearance gains will be minimal compared to dedicated lift kits. If your Grand Cherokee currently has rear sag from constant loads, restoring proper ride height may regain some clearance lost to sagging. For fitting larger tyres, you'll typically need a complete suspension lift kit that raises both front and rear to maintain proper vehicle rake and provide adequate clearance in the wheel arches. Contact our team to discuss complete lift kit options if increased tyre clearance is your primary goal.

Perfect for Heavy Loaded Outback Touring
These Toughdog rear coils have completely transformed my WK2's handling with a full touring setup including dual batteries, fridge and long-range tank. Did the Canning Stock Route last month and the ride quality was exceptional even when fully loaded - no more sagging or bottoming out on the whoops. Fitment was spot-on and they've maintained their height perfectly after 8000km of corrugations and rocky tracks. Well worth the investment for serious remote travel.(5)
