Selecting the correct spring rate is critical for ride quality, safety, and longevity of your LandCruiser 300 suspension system. Spring rate must be based on constant accessory load only — accessories that remain on your vehicle at all times. Common constant front accessories include steel bull bars (30-50kg), winches (30-40kg), driving lights, UHF aerials, and bash plates. Occasional loads such as camping gear, passengers, towing, or caravan ball weight should NOT be factored into spring rate selection as this will result in an overly stiff ride and potential damage to other suspension components. When ordering, accurately assess your constant front-end weight and select the corresponding spring rate — if you're between ratings, always choose the lighter option for better ride quality.
Professional installation by a qualified automotive technician or 4WD suspension specialist is strongly recommended for coil spring replacement. Installation requires specialist spring compressors, torque wrenches, and knowledge of suspension geometry to ensure safe fitment. A full four-wheel alignment is mandatory after installation to restore correct camber, caster, and toe settings — failure to align will result in premature tyre wear and compromised handling. Allow a 500km break-in period for springs to settle before final height measurements and alignment checks. For vehicles with significant lift or heavy constant loads, consider pairing these springs with upgraded control arms to restore suspension geometry and maximize component life.
Toughdog has earned its reputation as Australia's most trusted 4WD suspension brand through decades of engineering excellence, real-world outback testing, and unwavering commitment to quality. Every Toughdog component is designed to handle the unique demands of Australian touring — extreme heat, corrugated tracks, heavy loads, and long-distance reliability. Backed by comprehensive warranty coverage and supported by a nationwide network of specialist fitment centres, the Toughdog suspension range is the choice of professional tourers, tradespeople, and families who demand dependable performance from Cape York to the Nullarbor.
These Toughdog front coil springs are ideal for LandCruiser 300 owners who've added constant front-end accessories and need to restore ride height, improve handling, and eliminate suspension sag. Perfect for long-distance tourers carrying bull bars and winches, tradespeople with constant equipment loads, and families who've upgraded with protection gear and communication equipment. If you regularly tow caravans or camper trailers, pair these front springs with rear upgrades and consider airbag suspension for the ultimate load-carrying and leveling solution.

Yes, these Toughdog front coil springs are specifically engineered for all Toyota LandCruiser 300 Series models from 2021-onwards, including GR Sport and Sahara variants. They're designed as direct replacements that utilize factory mounting points and spring seats without requiring modification. The springs fit both diesel and petrol engine variants, though you must select the correct spring rate based on your constant front-end accessory load. If you've fitted aftermarket accessories or have a unique configuration, contact our team to confirm the ideal spring rate for your specific setup.
These Toughdog front coil springs are designed primarily to restore original ride height when carrying constant accessories, or provide a modest lift depending on the spring rate selected and your vehicle's current configuration. If you have a bull bar, winch, and other front accessories, the appropriate spring rate will typically restore factory height or provide 0-25mm lift over standard laden height. The actual lift achieved depends on your specific constant load — heavier accessories will compress springs more. For significant lift (40-50mm+), you'll need a complete lift kit with matched front and rear components including shocks and other hardware.
This kit includes a matched pair (2 pieces) of Toughdog front coil springs specifically engineered for the Toyota LandCruiser 300 Series. The springs feature progressive rate design, high-tensile steel construction, and corrosion-resistant powder coat finish. This is a springs-only kit — you'll reuse your factory spring isolators, top mounts, and other hardware. Shock absorbers, control arms, sway bar links, and other suspension components are sold separately and should be inspected during installation for wear. For a complete front-end upgrade, browse our LandCruiser 300 suspension packages or contact our team for a custom quote.
Yes, these Toughdog front coil springs are suitable for vehicles that regularly tow, as they help maintain proper front-end height and vehicle balance when combined with appropriate rear suspension upgrades. However, spring rate selection must be based only on constant front accessories (bull bar, winch, etc.) — NOT tow ball weight or caravan nose weight, as these are variable loads. When towing, the rear of your vehicle carries the ball weight, so matching rear springs or airbag suspension is essential to maintain level stance. For optimal towing performance, we recommend a complete front and rear suspension upgrade with load-rated shocks.
Upgraded control arms are not mandatory when installing Toughdog coil springs if you're staying close to factory ride height, but they're highly recommended if you're achieving any lift or running larger tyres. Control arms with adjustable caster and camber correction help restore proper suspension geometry after lift, improve steering response, and prevent premature wear on ball joints and bushings. For LandCruiser 300s with heavy bull bars, winches, or touring setups, heavy-duty control arms also provide superior strength and durability. Our team can advise on whether your specific setup would benefit from control arm upgrades during spring installation.
Yes, a full four-wheel alignment is absolutely mandatory after installing new coil springs on your LandCruiser 300. Replacing springs alters ride height and suspension geometry, which directly affects camber, caster, and toe angles — all critical for proper handling, tyre wear, and vehicle safety. Driving without post-installation alignment will cause rapid and uneven tyre wear, poor steering feel, and potentially dangerous handling characteristics. Book your alignment with a 4WD specialist who understands modified suspension geometry. After 500km of driving to allow spring settlement, a follow-up alignment check is also recommended.
When ordering Toughdog coil springs, you must select the spring rate that matches your permanent, constant accessory load — the weight that's on your vehicle 100% of the time. Different spring rates are available to accommodate varying constant loads such as no accessories (standard rate), light accessories like a small alloy bar (medium rate), or heavy accessories like steel bull bar plus winch (heavy rate). You cannot and should not select spring rates based on occasional loads like camping gear, passengers, or towing weight, as this will result in an excessively harsh ride when unladen and may damage other suspension components. Choose your spring rate honestly based on what's permanently fitted to your vehicle.
These Toughdog front coil springs primarily restore ride height when carrying accessories or provide modest lift, which may allow slightly larger tyres depending on your current setup and the spring rate selected. However, tyre clearance on the LandCruiser 300 is limited by guard/fender space, suspension compression travel, and steering lock clearance — not just ride height. For significant tyre size increases (33" or larger), you'll typically need a complete lift kit with matched front and rear lift, plus potentially wheel spacers, guard trimming, or diff drop brackets. Contact our team with your desired tyre size and current setup — we can recommend the complete suspension package needed for proper clearance and geometry.
Toughdog coil springs are backed by the manufacturer's comprehensive warranty covering defects in materials and workmanship under normal operating conditions. Warranty terms vary by component type and usage — our team will provide full warranty documentation with your order. To maintain warranty coverage, springs must be installed by a qualified technician, used within their specified load ratings, and paired with appropriate shock absorbers. Warranty does not cover damage from overloading, incorrect spring rate selection, installation errors, or collision damage. Keep your purchase receipt and installation records for warranty claims, and contact us immediately if you experience any issues.
Absolutely — Toughdog front coil springs are engineered to deliver excellent ride quality for daily driving, highway cruising, and long-distance touring, not just off-road performance. The progressive rate design provides a comfortable unladen ride for daily commuting while firming progressively under load for stability and control. When correctly matched to your constant accessory load, these springs maintain the LandCruiser 300's refined on-road manners while eliminating the sag and wallowing that occurs with heavy front accessories on factory springs. Thousands of LandCruiser owners across Australia rely on Toughdog suspension for comfortable daily driving combined with weekend touring capability.
Perfect Upgrade for Our Loaded 300 Series
Just got back from a two-week trip through the High Country with the family and these Toughdog front coils handled the extra weight of our roof tent and camping gear brilliantly.

Ride quality is firm but comfortable on the corrugations, and the kids don't complain about the bumps anymore. Well worth the investment for anyone doing regular touring with a heavy front-end setup.(5)
