Selecting the correct spring rate is critical for optimal performance, ride comfort, and component longevity. Your spring rate should be based on your constant accessory load only — the weight permanently fitted to your vehicle every day. Occasional loads such as camping gear, passengers, water, tools, or towing should NOT be factored into your spring rate selection, as over-sprung suspension will result in harsh ride quality and accelerated wear on bushes, shocks, and steering components.
Common front constant accessories: Steel bullbar, winch, dual batteries, UHF radios, driving lights. Common rear constant accessories: Steel tray or canopy, toolboxes, dual spare wheels, long-range fuel tank, water tank, drawer systems, roof rack.
If you regularly tow a caravan or heavy trailer, consider adding airbag suspension to your rear springs for variable load adjustment without compromising daily ride comfort.
Professional installation by a qualified mechanic or experienced 4WD workshop is strongly recommended. Leaf spring replacement requires specialised spring compressors, torque wrenches, and safety equipment. A four-wheel alignment is mandatory after installation to ensure correct camber, caster, and toe settings — protecting your tyres and steering components.
Allow a 500km break-in period for springs to settle and reach their optimal ride height. During this time, recheck all fastener torque settings as per manufacturer specifications. For vehicles with modified ride height or heavy constant loads, consider upgrading to heavy-duty control arms to restore correct suspension geometry and maximise handling performance.

These Toughdog rear leaf springs are specifically engineered for the Nissan Navara D21 series manufactured between 1986 and 1997. They're designed as a direct replacement for the factory rear leaf spring pack using original mounting points, spring hangers, and shackle locations. Before ordering, confirm your vehicle's series designation (check your compliance plate or VIN decoder) and measure your current spring width and eye-to-eye length to ensure correct fitment. If you're unsure about compatibility with your specific variant, our team can verify fitment using your VIN number.
Toughdog leaf springs are primarily designed to restore correct ride height after adding constant accessory weight, rather than providing aggressive lift. Depending on your selected spring rate and current load, you may experience a modest lift of 0-25mm compared to worn factory springs. The exact ride height achieved depends on your constant accessory load, spring rate selection, and the condition of your original springs. If you're looking for additional ground clearance and lift, consider a complete 4WD lift kit that includes matched front and rear components.
This kit includes a pair (left and right) of Toughdog heavy-duty rear leaf springs with centre bolts, fasteners, and nylon wear pads. The springs are supplied ready to install using your existing spring shackles, shackle bushes, spring pins, and U-bolts. You'll need to reuse your original mounting hardware or purchase new U-bolts and bushes separately if your existing components are worn or corroded. The kit does not include shock absorbers, bump stops, or spring hangers — these are sold separately if replacement is required.
Yes, these Toughdog leaf springs significantly improve towing stability and reduce rear-end sag when matched to your constant load requirements. However, it's critical to understand that your spring rate should be selected based on permanent accessory weight only — not towing loads. For optimal towing performance with variable trailer weights, we strongly recommend adding adjustable airbag suspension to your rear springs, allowing you to increase load support when towing while maintaining comfortable ride quality when driving unladen. This combination provides the best of both worlds for serious towers.
For a standard leaf spring replacement on a D21 Navara without significant ride height change, upgraded control arms are not typically required. However, if you're installing these springs as part of a larger lift kit or if your vehicle's suspension geometry has been altered, upgraded control arms can restore correct castor and camber angles for improved handling and reduced tyre wear. Inspect your existing control arm bushes, ball joints, and pivot points during installation — if these components show wear, it's an ideal time to upgrade to heavy-duty replacements for maximum suspension performance and longevity.
Yes, a full four-wheel alignment is mandatory after any leaf spring replacement. Even though leaf springs primarily affect ride height rather than steering geometry, any change in rear ride height can affect your vehicle's rake angle, which impacts front-end geometry and headlight aim. A professional alignment ensures correct camber, castor, and toe settings across all four wheels, protecting your tyres from uneven wear and maintaining safe, predictable handling characteristics. Most reputable workshops will refuse to complete a suspension installation without performing a final alignment check.
Yes, Toughdog manufactures these D21 Navara rear leaf springs in multiple spring rates to precisely match your constant accessory load. When ordering, you'll need to calculate the total weight of permanently fitted accessories including your tray or canopy, toolboxes, drawers, dual batteries, long-range fuel tank, water tanks, and spare wheels. It's critical to select spring rates based only on constant load — not occasional camping gear, passengers, or towing weights. Over-sprung suspension results in harsh ride quality and accelerated component wear, while under-sprung suspension causes excessive sag and poor handling.
These Toughdog leaf springs are designed primarily for load support and ride height restoration rather than aggressive lift for larger tyres. Any modest lift achieved may provide clearance for slightly larger tyres (typically 1-2 sizes up from factory), but this depends heavily on your wheel offset, guard profile, and whether you've installed other lift components. For fitting significantly larger tyres, you'll need a complete suspension lift including raised front coil springs or torsion bar adjustments, extended shocks, and possibly diff drops or castor correction. Always test-fit and check clearance at full suspension compression and steering lock before committing to larger rubber.
Toughdog suspension components are backed by a comprehensive manufacturer's warranty covering defects in materials and workmanship. The specific warranty period varies by component type and application — contact us for exact warranty terms for your D21 Navara leaf springs. To maintain warranty coverage, springs must be professionally installed according to manufacturer specifications, correctly rated for your vehicle's constant load, and serviced according to recommended intervals. Warranty does not cover damage from overloading, incorrect spring rate selection, improper installation, or normal wear and tear from vehicle use.
Absolutely — when correctly rated for your constant load, these Toughdog leaf springs deliver excellent ride comfort for daily commuting, highway touring, and around-town driving. Toughdog's multi-leaf progressive design provides a supple ride when unladen while maintaining load control when carrying weight. The key to comfortable daily driving is accurate spring rate selection — choose springs rated for your actual constant accessory weight, not projected maximum occasional loads. Over-sprung suspension will feel harsh and jiggly on smooth roads, while correctly matched springs offer a refined, controlled ride that rivals factory comfort with the added benefit of load-carrying capability.
Perfect Springs for Serious Outback Work
Been running these Toughdog rear leaf springs on my D21 for about 18 months now, covering everything from the Canning Stock Route to Cape York with a loaded canopy and dual spare setup. The ride quality is noticeably better than stock even when carrying 300kg+ of water, fuel and recovery gear, and they've completely eliminated the saggy rear end I had before. Fitment was spot-on with all the bushings and hardware needed, and they've handled countless corrugations without a single issue.(5)
Perfect Upgrade for Our Family Tourer
Fitted these Toughdog rear leaf springs to our D21 last month and they've been brilliant on our trips down the coast and out to the high country. The ride is noticeably smoother even with the camper trailer and all the kids' gear loaded up, and they handle the corrugations way better than the old worn-out factory springs. Really happy with the quality for the price, and they were pretty straightforward for my local mechanic to install.(5)
Perfect upgrade for our loaded camping setup
Fitted these Toughdog rear leaf springs to our D21 before our last trip to the High Country and what a difference they've made. The back end no longer sags when we've got the camper trailer hooked up plus all the kids' gear loaded in the tray. Ride quality is noticeably better on corrugated tracks too, which the whole family appreciated on those long dirt roads.(5)
Proper upgrade for my work ute
Chucked these Toughdog leaf springs on my old D21 about three months back and they've been copping a hiding with tools, timber and occasional beach runs without a whinge. The ride's heaps better than the sagging factory springs even when I'm loaded up with gear. Well worth the coin if you're using your Nav as an actual work truck.(5)
Perfect Upgrade for Loaded Outback Trips
Been running these Toughdog rear leaf springs on my D21 for six months now, including a Cape York run and multiple Simpson Desert crossings with a full load of water, fuel, and recovery gear. The difference in ride quality compared to the sagged factory springs is night and day – no more bottoming out on corrugations even with 300kg in the tray. Fitment was spot-on and they've handled everything the outback has thrown at them without a single issue.(5)
