Toughdog Rear 3" Coil Springs for Nissan Patrol GU/Y61 Wagon — Heavy Duty Lift

These Toughdog coil springs are designed to provide approximately 75mm (3 inches) of rear lift over factory standard ride height when the vehicle is unladen. Actual lift height will vary based on your vehicle's constant accessory load — heavily loaded vehicles will sit lower than unladen measurements suggest. For example, a Patrol with long-range fuel tank, dual batteries, drawer system, and rear bar may see 50-65mm of practical lift when loaded. The springs are progressive rate, meaning they compress proportionally under load while maintaining the improved ground clearance and load capacity benefits. For balanced vehicle stance, we recommend pairing these rear springs with appropriate front lift components to maintain correct suspension geometry and handling characteristics.

This kit includes two (2) Toughdog heavy duty rear coil springs specifically manufactured for the Nissan Patrol GU/Y61 wagon rear axle. The springs feature high-tensile steel construction with corrosion-resistant powder coat finish and progressive rate design for variable load performance. Please note that this is a rear springs only kit — front coil springs, shock absorbers, installation hardware, and spring compressor tools are not included and must be purchased separately. We strongly recommend upgrading your rear shock absorbers at the same time to match the increased spring rates and lift height, as factory shocks may not provide adequate damping control with lifted springs. Complete matching lift kits including front and rear springs plus shocks are also available.

Yes, these Toughdog rear coil springs are engineered to handle towing loads when correctly rated for your vehicle's total constant accessory weight plus towing requirements. The heavy duty progressive rate design provides excellent load support for caravan towing, camper trailers, and boat trailers up to your Patrol's maximum towing capacity and GVM limits. The springs help maintain level vehicle stance under combined accessory and towing loads, reducing rear squat and improving stability, braking performance, and headlight aim. For ultimate towing versatility and the ability to adjust ride height based on loaded versus unloaded conditions, consider adding airbag suspension which works in conjunction with these coil springs to provide on-demand load support. Always ensure your total vehicle weight including accessories, passengers, cargo, and towball weight remains within manufacturer GVM and GCM specifications.

While control arm upgrades are not mandatory for a 75mm rear lift on the GU Patrol (which uses a live axle with trailing arms and panhard rod rather than independent suspension), the increased ride height will affect suspension geometry and may accelerate wear on factory bushings. We recommend inspecting all rear suspension bushings, trailing arm bushings, and panhard rod bushings during spring installation, replacing any worn components to maximise the performance and longevity of your new springs. If you're also lifting the front of your Patrol (which does use independent front suspension with control arms), upgraded front control arms become important at lift heights exceeding 50mm to maintain correct castor angle, reduce CV joint angles, and restore proper suspension geometry. Our technical team can advise on complete suspension packages that address all geometry considerations for your specific lift height and intended use.

Yes, professional four-wheel alignment is mandatory after installing lifted rear coil springs on your Nissan Patrol GU/Y61, even though the rear axle is a live axle design with limited alignment adjustment. The rear axle alignment check ensures the panhard rod is correctly centred, the axle is square to the chassis, and thrust angle is within specifications to prevent dog-tracking and uneven tyre wear. More importantly, if you're also lifting the front (which is highly recommended for balanced stance), the independent front suspension will require full alignment including castor, camber, and toe adjustments to restore correct geometry. Driving with incorrect alignment after lifting can cause premature tyre wear, wandering steering, reduced handling performance, and increased stress on suspension components. Always have alignment performed by a shop experienced with lifted 4WDs who understand the specific requirements of modified Patrol suspension geometry.

Yes, Toughdog manufactures these rear coil springs in multiple load ratings to accommodate different constant accessory weights commonly carried on GU Patrol wagons. When ordering, you'll select the appropriate spring rate based on your vehicle's permanent accessory load — this includes the combined weight of all fitted accessories like long-range tanks, drawers, dual batteries, rear bars, spare wheel carriers, and rooftop tents (when stored). It's critical to select springs based only on constant loads, not occasional loads like passengers, camping gear, or groceries. Selecting springs that are too heavy for your actual constant load will result in harsh ride quality, reduced suspension articulation, and potential damage to shock absorbers and bushings. Our team can help calculate your constant accessory weight and recommend the optimal spring rate for your specific setup — contact us with a list of your fitted accessories for personalised spring rate advice.

With 75mm of rear lift and matching front lift, Nissan Patrol GU/Y61 wagons can typically accommodate tyres in the 33 to 35 inch diameter range (285/75R16 to 315/75R16 or equivalent) with minimal to no body modifications required. Actual tyre clearance depends on several factors including wheel offset, tyre brand (some brands run larger or wider than stated size), suspension compression and articulation, and whether you've fitted wider track control arms or wheel spacers. Some minor trimming of plastic inner guards or rear wheel arch lips may be required for full articulation clearance on 35 inch tyres, particularly if running wider offsets. We always recommend test-fitting tyres through full suspension cycle and steering lock before heading off-road to identify any contact points. Remember that larger tyres will affect gearing, fuel economy, speedo accuracy, and may require recalibration or diff ratio changes for optimal performance.

These Toughdog rear coil springs are backed by comprehensive manufacturer warranty covering defects in materials and workmanship under normal operating conditions. Toughdog stands behind their products with one of Australia's most respected warranty programs in the 4WD suspension industry, reflecting their confidence in engineering and manufacturing quality. Warranty coverage requires professional installation by a qualified technician, use within the manufacturer's specified load ratings, and proper maintenance of all associated suspension components. The warranty does not cover damage resulting from overloading beyond rated capacity, use of incorrect spring rates for your application, impacts from accidents or off-road obstacles, or wear resulting from damaged shock absorbers or worn bushings. For complete warranty terms, conditions, and duration specific to this product, please contact our team or refer to the warranty documentation included with your springs.

Absolutely — these Toughdog rear coil springs are specifically engineered to deliver excellent on-road comfort for daily driving while providing the load capacity and ground clearance benefits required for touring and off-road adventures. The progressive rate spring design ensures comfortable ride quality when unladen for daily commuting and highway cruising, progressively firming as load increases for controlled handling when towing or carrying camping equipment. Thousands of Australian Patrol owners rely on Toughdog suspension for everything from urban family transport to remote outback touring, proving the versatility and real-world comfort of this suspension design. For optimal on-road performance, ensure you select the correct spring rate for your constant accessory load (overly stiff springs will ride harsh when unladen), pair the springs with quality shock absorbers designed for lifted applications, and maintain proper tyre pressures adjusted for load conditions. Many owners report improved highway stability and reduced body roll compared to worn factory springs, particularly when towing or loaded.
