Selecting the correct spring rate is critical for optimal performance and ride quality. Spring rate should be based on your constant accessory load — the weight permanently installed in or on your vehicle. Occasional loads such as camping gear loaded for weekend trips or intermittent towing should NOT be factored into spring rate selection, as oversized springs will result in harsh ride quality and potential damage to other suspension components.
Common constant rear accessories include: aluminium or steel canopy/tub, drawer systems, dual battery setups, long-range fuel tanks, rear water tanks, permanently mounted tool boxes, bull bars with rear tow bar, winch mounting accessories, and communication equipment. Weigh your accessories or consult manufacturer specifications to calculate total constant load accurately.
Professional installation by a qualified 4WD suspension specialist is strongly recommended to ensure correct fitment, safety, and warranty compliance. While experienced DIY mechanics with appropriate equipment may complete the installation, proper spring compressor tools and safety procedures are mandatory. A full four-wheel alignment is essential after coil spring replacement to restore correct camber, caster, and toe settings — preventing premature tyre wear and maintaining safe handling characteristics.
After installation, allow a 500-kilometre break-in period for springs to settle and reach their final ride height. During this period, suspension geometry may continue to adjust slightly. For vehicles with modified ride height or heavy constant loads, consider pairing these springs with upgraded control arms to maintain optimal suspension geometry and articulation.

These Toughdog rear coil springs are ideal for Nissan Navara NP300 owners who have added accessories, regularly carry heavy loads, or experience rear sag with their current suspension. Touring enthusiasts with permanent canopy setups, drawer systems, and camping equipment will appreciate the restored ride height and improved handling. Tradespeople carrying tools, materials, and equipment benefit from enhanced load capacity without sacrificing daily drivability. For those frequently towing caravans or trailers, these springs work perfectly alongside airbag suspension systems for maximum towing stability and adjustable load support.

These Toughdog rear coil springs are specifically engineered for Nissan Navara NP300 (D23 series) models from 2015 onwards that are equipped with factory coil spring rear suspension (independent rear suspension). They will NOT fit NP300 variants with leaf spring rear suspension. To confirm compatibility, check underneath your Navara — coil spring models have independent coil springs at each rear wheel rather than leaf spring packs. If you're unsure about your vehicle's rear suspension type, contact our team with your VIN number for confirmation before ordering.
These Toughdog rear coil springs are primarily designed to restore or maintain factory ride height while providing enhanced load-carrying capacity for vehicles with constant accessory loads. Lift height varies depending on the spring rate selected and your vehicle's current laden weight. Typically, vehicles experiencing rear sag from added accessories will see ride height restored to factory specifications or slightly above (10-20mm). These are not aggressive lift springs — for significant ride height increases, consider a complete suspension lift kit that includes matched springs, shocks, and hardware.
This kit includes a pair (2 pieces) of Toughdog heavy-duty rear coil springs engineered specifically for the Nissan Navara NP300 coil rear suspension. The springs feature progressive rate design and corrosion-resistant powder coating. This kit does NOT include shock absorbers, upper or lower control arms, spring seats, bushings, or installation hardware, which must be purchased separately if replacement is required. Shock absorbers are particularly important — if your existing shocks have covered more than 60,000km or show signs of wear, consider upgrading to matched performance dampers for optimal results.
Yes, Toughdog rear coil springs are excellent for towing applications when the correct spring rate is selected to match your vehicle's constant accessory load. They help reduce rear squat under towing loads and maintain more level vehicle attitude for safer handling and improved headlight aim. However, for maximum towing performance and adjustability, many Navara owners combine upgraded coil springs with airbag suspension systems. Airbags allow you to adjust support based on trailer weight and provide superior load levelling — browse our airbag suspension range for towing-specific solutions that work perfectly with these Toughdog springs.
For stock or near-stock ride height applications, factory control arms typically remain adequate when installing these Toughdog rear coil springs. However, if you're running a complete lift kit, have experienced control arm wear, or want to improve articulation and alignment adjustability, upgraded aftermarket control arms are recommended. Quality aftermarket arms offer improved geometry correction, better articulation, stronger construction, and often include adjustability for precise alignment settings. They're particularly beneficial for vehicles used in serious off-road conditions or with significant modifications. Check our control arm range for NP300-specific options.
Yes, a complete four-wheel alignment is absolutely mandatory after installing new rear coil springs on your Navara NP300. Replacing coil springs alters suspension geometry including camber, toe, and in some cases affects front-end geometry through changed vehicle attitude. Without proper alignment, you'll experience accelerated and uneven tyre wear, compromised handling, reduced fuel economy, and potentially unsafe steering behaviour. Take your vehicle to a reputable alignment specialist who has experience with 4WD vehicles and modified suspensions — they should check and adjust all four wheels to manufacturer specifications or modified vehicle specifications if you're running a lift.
Absolutely — Toughdog rear coil springs are available in multiple spring rates to accommodate various constant load configurations. During ordering, you'll select the spring rate that matches your vehicle's permanent accessory weight. It's critical to select spring rate based ONLY on constant loads (permanently installed equipment like canopies, drawers, tanks, tool boxes), not occasional loads like camping gear or intermittent towing. Selecting too heavy a spring rate will result in harsh ride quality, reduced traction, and potential damage to other suspension components. If you're unsure which rate suits your setup, contact our suspension specialists who can calculate the appropriate spring rate based on your specific accessories and usage.
These Toughdog rear coil springs primarily restore ride height rather than provide aggressive lift, so tyre clearance gains will be minimal if your vehicle is currently at factory height. Most NP300 Navaras can accommodate up to 265/70R17 or 265/65R18 tyres with minor trimming at stock height. For significantly larger tyres (285mm+ width), you'll need a complete suspension lift kit that raises both front and rear, potentially combined with body lifts and guard trimming. Tyre clearance also depends on wheel offset, tyre brand/tread pattern, and suspension articulation. Always test-fit and check clearance at full steering lock and full compression before committing to larger tyres.
Toughdog stands behind their products with comprehensive manufacturer warranty coverage that protects against defects in materials and workmanship. Specific warranty terms and duration vary by component and application — contact us for detailed warranty information specific to these rear coil springs. To maintain warranty validity, professional installation is typically required along with proof of purchase and installation records. Warranty does not cover wear and tear from normal use, damage from accidents or misuse, or failure resulting from incorrect spring rate selection. Toughdog's reputation for standing behind their products gives you confidence in your investment.
Yes, these Toughdog rear coil springs are absolutely suitable for daily driving, highway touring, and urban use. Unlike aggressive competition springs designed purely for off-road performance, Toughdog engineers their coil springs with progressive rate characteristics that balance load-carrying capability with on-road comfort. When the correct spring rate is selected for your constant load, you'll experience comfortable ride quality unladen, with enhanced support when loaded. The springs maintain stable highway handling, reduce body roll during cornering, and provide controlled ride characteristics across all driving conditions from city commutes to cross-country touring on sealed and unsealed roads.
Finally sorted the sagging rear end
Been running these Toughdog coils on my NP300 for about six months now and they've handled everything I've thrown at them - fully loaded with tools during the week and towing the camper trailer on weekends. The ride is heaps better than the old springs, no more bottoming out on corrugated dirt roads. Well worth the money for anyone who actually uses their ute for work.(5)
Proper upgrade for outback touring
Been running these Toughdog rear coils on my NP300 for six months now, including a brutal run through the Simpson and Cape York. The difference in load handling is massive – carrying dual spare wheels, long range tank, and full camping gear without any of that awful squat I had with the factory springs. Ride quality is surprisingly good too, soaks up the corrugations way better than I expected from heavy duty springs.(5)
Perfect Upgrade for Our Loaded Navara
These Toughdog rear coils have completely transformed our NP300 for family camping trips. We regularly load up the tray with tents, swags, water tanks and all the camping gear, and the difference in handling and ride quality compared to the saggy factory springs is night and day. Installation was straightforward and they've been brilliant through everything from highway cruising to corrugated tracks out past Carnarvon Gorge. Well worth the investment if you're serious about touring with a decent load on board.(5)
