Selecting the correct spring rate is critical for optimal performance and longevity. Measure your constant accessory load — the weight permanently installed on your Fortuner including bull bars, rear protection, drawer systems, dual batteries, long-range fuel tanks, roof racks with permanent loads, water tanks, and recovery equipment. Do not include occasional loads like camping gear, fridges, or passengers as these are temporary. Common rear constant loads include rear bars (20-40kg), drawer systems (40-80kg), dual battery setups (20-30kg), long-range tanks (10-20kg empty), and permanent roof rack loads (10-30kg). Total these weights to determine your rear constant load, then select the appropriate spring rate during checkout. Over-rating your springs will result in harsh ride quality and potential damage to other suspension components, while under-rating causes sagging and poor handling.
Professional installation by a qualified 4WD suspension specialist is strongly recommended for these rear coil springs. Installation requires specialized spring compressors, torque tools, and safety equipment to ensure correct fitment and safe handling of compressed springs. A complete four-wheel alignment is mandatory after installation to ensure correct tracking, minimize tyre wear, and maintain handling characteristics. Allow a 500km break-in period for springs to settle to their final ride height and for the spring coating to properly seat. For complete suspension transformation and optimized geometry at lifted heights, consider pairing these springs with upgraded control arms and quality shock absorbers matched to your spring rates.

These Toughdog rear coil springs are ideal for Toyota Fortuner owners who carry constant rear accessory loads, tow caravans or trailers regularly, or have experienced rear sagging from factory spring fatigue. Perfect for touring families who need reliable load support for extended trips, tradespeople who carry permanent equipment and tools, and grey nomads towing camper trailers across Australia. If you frequently carry heavy loads or tow near your vehicle's capacity, consider adding airbag suspension for variable load adjustment and enhanced towing stability without changing spring rates.

These Toughdog rear coil springs are engineered to fit Toyota Fortuner models including both the 2005-2015 (KUN51R/KUN60R) and 2015-current (GUN156R/GUN166R) series. Fitment is confirmed for all engine variants including 2.8L and 4.0L petrol and diesel configurations. To verify exact compatibility for your specific build date and variant, use our online parts finder tool or contact our technical team with your VIN number. Different spring rates are available to match your constant load requirements, so correct rate selection is essential for optimal performance.
These Toughdog rear coil springs are primarily designed for load support and ride height restoration rather than aggressive lift. Depending on your selected spring rate and constant load, they will restore factory ride height if sagged or provide approximately 0-30mm of additional lift when paired with appropriate shock absorbers. The actual lift achieved varies based on spring rate selection, total vehicle weight, and constant accessory loads. For maximum lift and complete suspension transformation, these springs work best as part of a full Toughdog lift kit system with matched front coils and shock absorbers.
This kit includes a pair (2 pieces) of Toughdog heavy-duty rear coil springs specifically rated for your chosen constant load capacity. The springs feature premium high-tensile steel construction with corrosion-resistant coating and comply with Australian Design Rules. Installation hardware such as spring isolators, U-bolts, and bump stops are not included and typically reuse existing components or can be purchased separately. Shock absorbers, front coil springs, and other suspension components are sold separately and should be selected to match your spring rates for balanced performance.
Yes, these Toughdog rear coil springs are excellent for towing applications when correctly rated for your constant load and tow ball weight. They significantly reduce rear squat under tow ball loads, improving stability, braking performance, and headlight aim when towing caravans, camper trailers, or boat trailers. The progressive spring rate design provides firm support under load while maintaining comfortable ride quality when not towing. For maximum towing versatility and the ability to adjust for varying loads, consider supplementing these springs with airbag suspension which allows on-demand pressure adjustment for different towing scenarios.
Control arm upgrades are not mandatory for these rear coil springs if you're achieving minimal lift (under 30mm) and maintaining near-factory ride height. However, if you're installing a complete lift kit or experiencing significant ride height increase, upgraded control arms are highly recommended to restore correct suspension geometry, maintain proper CV joint angles, and prevent premature wear. Adjustable control arms allow fine-tuning of castor and camber angles post-installation for optimal handling and tyre wear. Consult with a qualified suspension specialist during installation to assess whether your specific setup requires control arm upgrades.
Yes, a complete four-wheel alignment is absolutely mandatory after installing these rear coil springs. Any change to suspension geometry or ride height affects wheel alignment angles including toe, camber, and castor, which directly impact handling, steering response, and tyre wear. Professional alignment ensures your Fortuner tracks straight, minimizes abnormal tyre wear patterns, and maintains safe handling characteristics. The alignment should be performed after installation and again after the 500km break-in period once springs have fully settled to their final ride height for most accurate adjustment.
Yes, Toughdog offers these rear coil springs in multiple spring rates to accommodate different constant load configurations. It's critical to select the spring rate that matches your permanent accessory load — not occasional loads. During checkout, accurately calculate the total weight of permanently installed accessories including bull bars, rear bars, drawer systems, dual batteries, roof racks with permanent loads, and water tanks. Do not include temporary loads like camping gear, passengers, or fridges as these are occasional. Selecting too heavy a spring rate results in harsh ride quality and potential component damage, while too light causes sagging and poor handling.
These rear coil springs provide modest lift (typically 0-30mm depending on spring rate and load), which may allow slightly larger tyres than factory specification, but significant tyre size increases usually require additional modifications. Tyre fitment depends on multiple factors including wheel offset, suspension compression travel, body mount positions, and whether you've installed a complete lift kit with front and rear components. For the Toyota Fortuner, 265-275mm width tyres are commonly achievable with moderate lift, but larger sizes may require guard trimming or body modifications. Always test fit tyres at full suspension compression and steering lock before committing to purchase.
Toughdog coil springs are backed by comprehensive manufacturer warranty coverage against defects in materials and workmanship, providing peace of mind for your investment. Specific warranty terms and duration vary by component and application, so refer to the warranty documentation included with your springs or contact our team for detailed coverage information. Warranty claims require proof of professional installation, appropriate spring rate selection for actual constant load, and proper maintenance including regular inspections. Keep all installation receipts and alignment records to support any potential warranty claims.
Absolutely — these Toughdog rear coil springs are engineered to deliver excellent daily driving comfort while providing superior load support when needed. When correctly rated for your constant load, they maintain comfortable ride quality for urban commuting, highway driving, and school runs while eliminating the rear sag common with factory springs on loaded vehicles. The progressive spring rate design ensures the springs aren't overly harsh when unladen, providing compliance over bumps and road imperfections. Thousands of Australian Fortuner owners use Toughdog springs daily for both city driving and weekend touring with excellent results.
