Selecting the correct spring rate is critical for optimal ride quality, handling and component longevity. You must choose your spring rate based on current constant load only — the accessories and equipment permanently fitted to your vehicle's front end. Common constant loads include steel bull bars (30-50kg), winches (30-40kg), heavy-duty batteries, UHF radios, driving lights, and roof rack systems. Occasional loads such as camping gear, recovery equipment, passengers, and towing loads should NOT be factored into spring rate selection as they are temporary and variable. Selecting a spring rate that's too heavy for your actual constant load will result in harsh ride quality, reduced articulation off-road, and potential premature wear to other suspension components including shock absorbers and bushings.
Professional installation by a qualified automotive technician or experienced 4WD mechanic is strongly recommended for this front coil spring upgrade. The installation process requires specialized spring compressors, safety equipment, and knowledge of suspension geometry to ensure safe and correct fitment. A full wheel alignment is mandatory after installation to ensure proper steering angles, prevent premature tyre wear, and maintain safe handling characteristics. Allow approximately 500 kilometres of varied driving conditions for the new springs to properly settle and achieve their final ride height. For optimal performance and safety, consider pairing these springs with upgraded suspension components including quality shock absorbers, new bump stops, and fresh suspension bushings.

These heavy-duty front coil springs are ideal for Navara NP300 owners who have added front-end accessories and need to restore or improve ride height while maintaining comfortable on-road handling. Perfect for tradespeople carrying tools and equipment, touring enthusiasts with bull bars and winches, or anyone experiencing front-end sag from constant accessory weight. If you regularly carry significant rear loads or tow heavy trailers, consider complementing your suspension upgrade with airbag suspension for the rear to provide adjustable load support and level stance under variable weight conditions.

These ToughDog front coil springs are specifically engineered for Nissan Navara NP300 (D23 series) models from 2015 to current that are equipped with rear leaf spring suspension. They will not fit NP300 variants with rear coil suspension as those models have different front spring specifications and geometry. To confirm exact fitment for your specific model year and variant, check the vehicle compatibility table on this page or contact our suspension experts who can verify fitment using your VIN number. You can also use our parts finder tool to search all compatible suspension components for your exact Navara configuration.
The primary purpose of these ToughDog front coil springs is to restore factory ride height when replacing worn or sagging springs, or to support the weight of constant front-end accessories like bull bars and winches without excessive sag. The actual lift height achieved depends on the spring rate selected and your current constant load configuration. When replacing worn factory springs on a vehicle with heavy front accessories, you may see 20-40mm of restored height. These are not aggressive lift springs but rather load-appropriate replacement springs designed to maintain proper suspension geometry. For greater lift heights, consider a complete lift kit that includes matched springs and extended shock absorbers.
This kit includes two (2) ToughDog heavy-duty front coil springs manufactured from heat-treated spring steel with corrosion-resistant powder coat finish. The specific spring rate you select during checkout determines the load capacity of the springs supplied. This kit does NOT include shock absorbers, upper spring seats, spring isolators, bump stops, or any installation hardware, as these components are typically reused from your existing setup or purchased separately if replacement is needed. We recommend inspecting all associated suspension components during installation and replacing worn items for optimal performance and safety.
These front coil springs are designed to handle constant front-end accessory weight and are not directly affected by towing loads, which primarily impact rear suspension. However, selecting the correct front spring rate is important for maintaining proper vehicle balance and steering control when towing heavy trailers. You should choose your front spring rate based only on permanent front accessories, not on anticipated towing loads. For comprehensive towing performance, pair these front springs with appropriately rated rear leaf springs or airbag suspension that can handle your specific trailer weight. This combination ensures level vehicle stance, proper headlight aim, and safe handling characteristics when towing.
Control arm upgrades are not mandatory when installing these front coil springs, as they are designed to work within the Navara NP300's factory suspension geometry range. However, if you're experiencing worn control arm bushings, ball joint play, or if you're building a comprehensive suspension upgrade, replacing your control arms with heavy-duty aftermarket units can provide improved durability, better articulation off-road, and enhanced steering precision. Control arms become more important when combining coil springs with lift kits or when running larger tyres. Inspect your existing control arms during spring installation and replace if wear is evident for optimal performance and safety.
Yes, a full four-wheel alignment is absolutely mandatory after installing new front coil springs on your Navara NP300. Changing front springs alters ride height and suspension geometry, which directly affects camber, caster and toe angles that determine steering response, tyre wear patterns and handling characteristics. Driving without proper alignment after spring installation can cause rapid and uneven tyre wear, poor handling, steering pull, and potentially unsafe driving dynamics. The alignment should be performed after the springs have been installed and the vehicle has been driven approximately 500 kilometres to allow the new springs to settle to their final ride height for the most accurate alignment settings.
When ordering these ToughDog front coil springs, you must select a single spring rate that matches your current constant load — the permanent accessories and equipment fitted to your vehicle right now. You cannot order multiple spring rates in one kit, and you should not select a heavier spring rate anticipating future accessories you might add later. Installing springs that are too heavy for your current constant load will result in harsh ride quality, reduced suspension travel, poor off-road articulation, and potential damage to other suspension components. If you later add significant weight such as a steel bull bar or heavy winch, you would need to upgrade to appropriately rated springs at that time to maintain optimal ride quality and performance.
These front coil springs primarily restore or slightly improve ride height based on spring rate selection and current load, but they are not designed as aggressive lift springs specifically for tyre clearance. The ability to fit larger tyres depends on your total lift height achieved from both front and rear suspension, as well as whether you've modified guards, bumpers or performed other clearance work. Most NP300 Navaras can accommodate modestly larger tyres (up to around 265/70R17) with the right spring selection and some minor trimming. For significantly larger tyre fitment, you'll need a complete suspension lift kit with extended shock absorbers, potentially body lifts, and possibly modified upper control arms to maintain proper suspension geometry and prevent rubbing during full articulation.
ToughDog front coil springs are backed by the manufacturer's warranty covering defects in materials and workmanship under normal use conditions. Warranty coverage typically extends for a substantial period, though specific terms and duration should be confirmed at time of purchase as they can vary by component type and application. The warranty does not cover damage caused by incorrect installation, improper spring rate selection, accident damage, modification, or wear from abnormal use. To maintain warranty validity, springs must be installed by a qualified technician, used within their designed load rating, and paired with appropriate shock absorbers. Keep your proof of purchase and installation records for any warranty claims.
Absolutely — these ToughDog front coil springs are engineered to provide excellent on-road ride quality for daily driving, commuting and highway touring when the correct spring rate is selected for your constant load configuration. ToughDog designs their springs with a progressive rate characteristic that delivers comfortable ride quality when unladen while providing firm, controlled support when loaded with accessories. Unlike harsh competition-oriented springs, these are designed for real-world Australian drivers who need their Navara to perform reliably as both a daily driver and weekend adventurer. The key to maintaining comfortable daily driving manners is selecting the spring rate that matches your actual constant accessory weight rather than overestimating and choosing springs that are unnecessarily stiff.
