Toughdog Suspension Lift Kit - Nissan Navara NP300 Coil Rear Complete Kit

This complete suspension system delivers approximately 40-50mm of lift at both the front and rear of your Navara NP300, measured from factory unladen ride height. Actual lift achieved will vary based on your selected spring rates, current accessory load, and vehicle condition. Heavier constant loads will compress springs more, potentially reducing final lift height, while lighter configurations may achieve the upper end of the lift range. After the initial 500km break-in period, expect springs to settle approximately 5-10mm as components bed in under load. This lift height allows fitment of larger diameter tyres (typically up to 32-33 inches with minimal trimming) and significantly improves ground clearance for off-road capability.

This complete kit includes everything needed to upgrade your NP300's suspension: two front strut assemblies with integrated springs, two front raised coil springs (rate selected at checkout), two rear raised coil springs (rate selected at checkout), two rear nitrogen gas shock absorbers, plus all necessary mounting hardware and bushings. The kit does not include upper control arms, extended brake lines, diff drop components, or other supplementary items that may be required depending on your specific build and lift requirements. Spring rates must be selected based on your current constant accessory load during the checkout process to ensure optimal performance and ride quality.

Absolutely — this Toughdog kit is specifically engineered to significantly improve towing performance compared to factory suspension. The upgraded spring rates and gas-charged shock absorbers dramatically reduce rear squat when coupling heavy caravans or boat trailers, maintaining proper suspension geometry and safer handling characteristics under load. When selecting your rear spring rate, include the estimated towball weight as part of your constant load calculation if you tow regularly. For extreme towing applications or variable loads, consider supplementing this kit with airbag suspension for on-demand load support and fine-tuned ride height adjustment while towing. Professional wheel alignment after installation is essential to ensure optimal towing stability and tyre wear.

Upper control arms are not always mandatory with this lift height, but they are highly recommended for optimal suspension geometry, improved handling, and extended component life. The 40-50mm lift provided by this kit will alter your Navara's caster and camber angles beyond factory specifications, which can lead to accelerated ball joint wear, reduced steering precision, and compromised handling characteristics. Upgraded adjustable upper control arms allow technicians to restore correct geometry during wheel alignment, improving on-road manners and off-road articulation. If you plan extensive touring, carry heavy loads regularly, or want the best possible performance from your suspension investment, budget for quality aftermarket upper control arms as part of your build.

Yes, a professional four-wheel alignment is absolutely mandatory after installing this or any lift kit on your Navara NP300. Changing suspension height significantly alters steering geometry including caster, camber, and toe angles, which directly affects handling, steering response, and tyre wear patterns. Driving without proper alignment can cause rapid and uneven tyre wear, pulling to one side, wandering at highway speeds, and potentially dangerous handling characteristics, especially when loaded or towing. Book your alignment with a reputable workshop that has experience with lifted four-wheel drives and can accommodate modified ride heights. Allow the 500km break-in period to complete before final alignment for best results.

Yes — in fact, selecting different spring rates for front and rear is essential for achieving optimal performance based on your specific accessory configuration. During checkout, you'll specify front and rear spring rates independently based on your current constant accessory load for each axle. Most Navara NP300 builds carry heavier loads at the front (bull bar, winch, driving lights) and rear (canopy, drawer systems, dual batteries), requiring different spring rates to maintain level ride height and balanced handling. Toughdog offers multiple spring rate options to accommodate light, medium, and heavy constant loads. Calculate your actual accessory weights carefully — selecting springs that are too heavy will result in harsh ride quality, while under-rated springs cause excessive sagging and poor handling.

With the 40-50mm of lift provided by this Toughdog kit, most Nissan Navara NP300 owners can comfortably fit tyres up to 32-33 inches in diameter (approximately 265/70R17 or 265/75R16) with minimal to no trimming of guards or body mounts. Larger tyres in the 33-34 inch range may require minor trimming of plastic guard liners and potentially offset wheels to avoid rubbing at full steering lock or during suspension compression. Tyre fitment is also affected by wheel offset, tyre brand (some measure larger than stated), and suspension travel during articulation. Always test fit new tyres through full steering range and compression cycles before committing to off-road use. Remember that larger tyres may require speedo recalibration and can affect gearing, fuel economy, and braking performance.

Toughdog backs this complete suspension kit with comprehensive manufacturer warranty coverage, providing peace of mind for your investment in premium Australian-engineered suspension components. Warranty terms cover manufacturing defects and premature component failure under normal use conditions, with local Australian support and replacement parts readily available through our nationwide network. Specific warranty duration varies by component type — contact us for detailed warranty terms and conditions. Warranty coverage requires professional installation, proper vehicle alignment post-fitment, and use within manufacturer specifications including correct spring rate selection. Retain your proof of purchase and installation documentation to facilitate any warranty claims. Toughdog's reputation for honouring warranty commitments is a key reason Australian four-wheel drivers trust the brand.

This Toughdog suspension system is absolutely suitable — and excellent — for daily driving while also delivering superior off-road capability when needed. Unlike harsh competition-focused suspension, Toughdog engineering prioritizes balanced performance with progressive spring rates and optimized damping curves that maintain factory-like comfort during commuting, highway cruising, and urban driving. The nitrogen gas shock technology provides consistent, fade-free damping whether you're navigating city traffic or tackling corrugated outback roads. Many owners report improved ride quality compared to worn factory suspension, especially when carrying typical accessory loads. The key to daily driving comfort is selecting the correct spring rates based on your actual constant load — avoid over-specifying spring rates, which creates unnecessarily harsh ride quality for everyday use.
