Tough Dog 40mm Lift Kit for Toyota Prado 120 Series Grande — Complete 4WD Suspension Upgrade

This Tough Dog kit is engineered to deliver approximately 40mm of lift over factory ride height when installed with the correct spring rates for your vehicle's constant accessory load. Actual lift height can vary by ±5-10mm depending on your specific vehicle's existing suspension condition, accessory weight distribution, and whether you have the petrol or diesel engine variant which affects front-end weight. The 40mm lift provides sufficient clearance for 265-275mm tyres on standard offset wheels without rubbing, improves approach and departure angles for off-road driving, and allows fitment of slightly larger diameter shock absorbers for improved damping performance. Remember that all lifted springs will settle 5-10mm during the first 500km break-in period as the coils compress and seat properly under load.

This complete lift kit includes two front raised coil springs, two rear raised coil springs, and four shock absorbers of your choice (foam cell, nitro gas, or adjustable variants). The springs are precision-wound from high-tensile Australian steel and powder-coated for corrosion resistance, while shock absorbers feature Tough Dog's proven multi-stage valve technology. All necessary mounting hardware is included for a complete front and rear installation. Please note that upper control arms, extended brake lines, differential drop kits and wheel alignment are sold separately and may be required depending on your final lift height and vehicle usage — our team can advise on additional components needed for your specific setup.

Yes, this Tough Dog lift kit is excellent for towing applications as the load-rated rear coil springs provide additional support for caravan, boat trailer or camper towing up to your Prado's maximum GVM and GCM ratings. The upgraded springs significantly reduce rear-end squat under tow ball weight, improving stability at highway speeds and maintaining proper headlight aim when towing. When selecting spring rates, remember to choose based only on your constant accessory load (not towing weight), as the springs are designed to support the tow ball download dynamically while maintaining correct ride height. For even greater towing control and the ability to level your Prado when hitched up, consider adding airbag suspension to the rear axle for on-the-fly adjustability that complements this lift kit perfectly.

While not strictly mandatory for a 40mm lift, upgrading to aftermarket upper control arms is highly recommended if your Prado carries significant frontal weight from bull bars, winches or long-range tanks. A 40mm lift changes the geometry of your front suspension, altering ball joint angles and potentially reducing steering responsiveness and increasing bump steer on corrugated roads. Adjustable upper control arms allow your installer to dial in correct camber and caster angles during wheel alignment, restoring factory-like handling characteristics and maximising tyre contact patch for better braking and cornering grip. For Prados used primarily for touring and off-road work, the investment in quality control arms pays dividends in ride comfort, steering precision and reduced maintenance costs from premature wear on ball joints and bushings.

Yes, a professional four-wheel alignment is absolutely mandatory immediately after installing this lift kit — this is not optional. Lifting your Prado 120 Grande changes the camber, caster and toe angles of both front and rear suspension, and without proper realignment you will experience rapid and uneven tyre wear (particularly on inside or outside edges), wandering steering, reduced braking performance and compromised stability at highway speeds. A proper alignment ensures your tyres make correct contact with the road surface, maximises component life, and restores predictable handling characteristics. The alignment should be performed with the vehicle at normal ride height with typical occupants and gear loaded, and all suspension bolts must be torqued to specification before alignment commencing. Budget $150-250 for a quality four-wheel alignment at a reputable suspension or tyre specialist.

Selecting the correct spring rate is critical for ride quality, component longevity and safety — measure or calculate the constant load you carry permanently in your vehicle including bull bars, winches, long-range tanks, drawer systems, second batteries, roof racks and any gear that stays in the vehicle year-round. Do NOT include occasional loads like camping gear for weekend trips, towing loads, or passengers, as this will result in over-sprung suspension that delivers a harsh ride and can damage other components through excessive force transfer. If you're carrying a heavy bull bar and winch setup (50-80kg) plus long-range tank (40kg when full), you'll need heavier front springs than a Prado with minimal accessories. If you're unsure about your constant load weight, our suspension experts can guide you through a weighbridge measurement or visual assessment to ensure you get the perfect spring rates for your exact setup and usage pattern.

This 40mm Tough Dog lift kit provides clearance for 265-285mm diameter tyres depending on your wheel offset, tyre brand (as tread patterns vary in actual width), and whether you're willing to do minor trimming of plastic inner guards. On standard offset wheels (around +20 to +30mm), most owners can comfortably fit 265/70R17 or 265/65R18 tyres with no modifications required. More aggressive fitments like 285/70R17 may require slight guard trimming and potentially offset wheels to prevent rubbing at full steering lock or during suspension compression on harsh bumps. Always test-fit your chosen tyre and wheel combination before committing to a purchase, and remember that larger, heavier tyres will affect fuel economy, acceleration and braking performance compared to factory sizes.

Tough Dog provides comprehensive warranty coverage on all suspension components when installed by a qualified professional and used within the manufacturer's specified load ratings and vehicle applications. Coil springs typically carry a multi-year structural warranty against breakage or permanent deformation under normal use, while shock absorbers are covered against manufacturing defects and seal failure for a substantial period from date of purchase. Warranty terms require that components are not modified, that vehicle GVM and GCM are not exceeded, that the kit is installed by a qualified technician, and that regular maintenance schedules are followed. Always retain your proof of purchase and installation receipts, and have your installer complete any warranty registration cards at the time of fitment. For specific warranty duration and terms for this kit, contact our team or refer to the documentation included with your shipment.

Absolutely — this Tough Dog lift kit is engineered to maintain excellent on-road manners for daily commuting, highway touring and urban driving while delivering enhanced off-road capability when needed. When installed correctly with a professional wheel alignment and the correct spring rates for your constant load, you should experience near-factory ride quality on sealed roads with only marginally increased body roll in corners due to the modest 40mm lift height. The key to comfortable daily driving is choosing spring rates that match your actual constant accessory weight — over-sprung suspension (from choosing too-heavy springs) will result in a harsh, bouncy ride that never settles properly on highway undulations. Selecting quality shock absorbers from Tough Dog's foam cell or adjustable range will further enhance comfort on corrugated roads and long-distance touring while maintaining control and stability at highway speeds with or without a loaded vehicle or trailer.
