Selecting the correct spring rate is crucial for optimal performance and ride comfort in your FJ Cruiser. When choosing your spring rate, calculate only the constant load — accessories and equipment that remain in or on your vehicle permanently, not occasional cargo or passengers. Constant loads include rear bars, tow bars, dual battery systems, long-range fuel tanks, drawer systems, fridge slides, roof racks with awnings, rear tire carriers, and permanently mounted recovery equipment. Do not factor in occasional loads like camping gear, water, luggage, or towing weight, as selecting springs that are too heavy will result in a harsh, uncomfortable ride and may cause premature wear to other suspension components including shock absorbers and bushings.
Common Rear Constant Loads: Rear steel bar or alloy bar (20-35kg), swing-away spare wheel carrier (30-50kg), dual battery and inverter system (25-40kg), long-range fuel tank when full (80-120kg), drawer system with fridge slide (40-60kg), roof rack and awning weight transferred to body (15-25kg), tow bar and electric brake controller (15-20kg). Add these together for your total constant rear load, then consult spring rate specifications or contact our team for the perfect match.
Professional installation by a qualified 4WD suspension specialist is strongly recommended for rear coil spring replacement on the FJ Cruiser. The installation requires proper spring compressors, torque specifications for critical fasteners, and expertise to safely handle compressed springs and maintain correct suspension geometry. A comprehensive wheel alignment is mandatory after installation to ensure correct camber, caster, and toe settings, preventing premature tire wear and maintaining optimal handling characteristics. All Toughdog springs require a 500km break-in period where the springs will settle into their final operating height — avoid maximum loads during this initial period and have ride height checked after break-in is complete.
For FJ Cruiser owners installing a complete suspension upgrade, consider pairing these rear springs with quality suspension components including new shock absorbers, spring isolators, and bushings to maximise performance and longevity of your investment.

These Toughdog rear coil springs are specifically engineered to fit all Toyota FJ Cruiser models produced from 2010 to 2018, covering the entire Australian market production run. They're designed as a direct replacement for factory rear coil springs and maintain all OEM mounting points and specifications. The springs fit both left-hand drive and right-hand drive FJ Cruiser variants sold in Australia. If you've modified your FJ Cruiser with aftermarket suspension components or have any fitment concerns, our team can verify compatibility with your specific vehicle configuration before you order.
Toughdog rear coil springs for the FJ Cruiser are primarily designed to restore factory ride height while accommodating additional accessory weight, rather than providing significant lift. Depending on the spring rate selected and your vehicle's current condition, you can expect to restore sagging rear height and potentially gain 0-25mm of additional height when accounting for accessory loads. The actual lift achieved varies based on your constant load — heavier spring rates supporting more weight will sit higher than lighter rates. These springs are ideal for maintaining proper stance with aftermarket accessories rather than achieving extreme lift, which would require a complete suspension system upgrade.
This kit includes a pair (two) of Toughdog heavy-duty rear coil springs manufactured specifically for the Toyota FJ Cruiser rear axle. The springs feature premium Australian-grade steel construction with corrosion-resistant powder coat finish. Please note that shock absorbers, spring isolators, U-bolts, bushings, and other suspension hardware are not included and must be purchased separately if replacement is required. We recommend inspecting all related suspension components during spring installation and replacing worn parts to ensure optimal performance and safety of your complete rear suspension system.
Yes, Toughdog rear coil springs significantly improve towing performance by providing enhanced rear-end support and reducing rear squat when hitched to camper trailers, boat trailers, or caravans. By selecting the appropriate spring rate for your setup, you'll maintain better suspension geometry under towing loads, improving stability, braking performance, and steering control. However, remember that towing weight should not be factored into your spring rate selection — choose springs based on constant accessory load only. For frequent towing or variable loads, consider pairing these springs with adjustable airbag suspension for the ultimate in load management and leveling capability.
Control arm upgrades are not mandatory when installing Toughdog rear coil springs on your FJ Cruiser, as these springs maintain near-factory ride height and suspension geometry. However, if your vehicle has high mileage or you notice worn bushings, ball joints, or control arm components during inspection, replacement with upgraded parts is highly recommended for optimal performance. Control arm upgrades become more important if you're installing a complete lift kit or significantly increasing ride height. Inspect all suspension components during spring installation and replace any worn parts to ensure your suspension system operates as designed with proper alignment and handling characteristics.
Yes, a comprehensive four-wheel alignment is absolutely mandatory after installing new rear coil springs on your FJ Cruiser. Even though rear springs don't directly affect steering angles like front components, changing rear spring height alters the vehicle's overall stance and can affect weight distribution, which impacts alignment settings across all four wheels. Proper alignment ensures even tire wear, optimal handling characteristics, and maintains factory-specified suspension geometry. Your alignment technician should check and adjust camber, caster, and toe settings on all wheels to manufacturer specifications. Failing to align your vehicle after spring installation will likely result in premature tire wear and compromised handling performance.
Absolutely — Toughdog manufactures these FJ Cruiser rear coil springs in multiple spring rate options specifically to accommodate different load requirements and vehicle configurations. When ordering, you must select the spring rate that matches your vehicle's constant accessory load, which includes only permanently installed equipment like rear bars, tow bars, drawer systems, dual batteries, and long-range tanks. Do not select spring rates based on occasional loads like camping gear, passengers, or towing weight, as this will result in overly stiff springs and a harsh ride quality. Our team can help you calculate your constant load and recommend the perfect spring rate for your specific setup — contact us with your accessory list for expert guidance.
These Toughdog rear coil springs are designed primarily to restore factory ride height and support additional accessory weight rather than provide significant lift for larger tyres. While you may gain 0-25mm of additional height depending on spring rate and load, this modest increase won't typically allow for substantially larger tyres without additional modifications. Most FJ Cruisers can accommodate up to 285/75R16 or 33-inch tyres with minor trimming even at stock height. If your goal is to fit significantly larger tyres, you'll need a complete suspension lift kit that raises both front and rear, along with potential body modifications. These rear springs work perfectly to level your FJ Cruiser and support touring loads while maintaining factory tyre clearances.
Toughdog rear coil springs are backed by the manufacturer's comprehensive warranty, covering defects in materials and workmanship under normal operating conditions. Toughdog's warranty reflects their confidence in Australian engineering and manufacturing quality, providing peace of mind for your investment. Warranty coverage requires professional installation by a qualified technician, proper spring rate selection based on actual constant load, and normal usage within the product's design parameters. Warranty does not cover damage from accidents, improper installation, incorrect spring rate selection, or modifications beyond manufacturer specifications. For specific warranty terms, duration, and claim procedures, contact us directly or refer to the warranty documentation included with your springs.
Yes, Toughdog rear coil springs are absolutely suitable for daily driving, highway cruising, and urban commuting on your FJ Cruiser. Unlike cheap aftermarket springs that prioritize load capacity over comfort, Toughdog engineers their springs with progressive rate designs that deliver comfortable on-road handling when unladen while still providing the load support you need when touring or carrying gear. When you select the correct spring rate for your actual constant load, you'll enjoy comfortable highway ride quality, reduced body roll in corners, and improved stability at speed. The key is accurate spring rate selection — choosing springs that are too heavy will result in a harsh ride, while springs too light won't provide adequate support, so calculate your constant load carefully or consult our experts for guidance.
