Selecting the correct spring rate depends on your constant accessory load — the combined weight of permanently fitted accessories across your front and rear axles. For the Prado 120 Series, common front-end accessories include aftermarket bull bars (30-60kg), winches (30-40kg), upgraded batteries and dual battery systems (15-25kg), steel or alloy canopies (40-80kg for rear), long-range fuel tanks (varies), drawer systems (30-60kg rear), and roof racks with awnings (20-40kg). This Tough Dog kit is designed for medium to heavy constant loads, making it ideal for fully equipped touring setups and tradespeople carrying tools and equipment daily.
Professional installation by a qualified 4WD suspension specialist is strongly recommended to ensure correct fitment, safety compliance, and warranty validation. A full four-wheel alignment is mandatory after installing any lift kit to restore correct camber, caster, and toe settings — preventing premature tyre wear and maintaining safe handling. All Tough Dog suspension components require a 500km break-in period during which springs will settle and shocks will bed in; avoid extreme off-road use during this period. Depending on your lift height and load requirements, pairing this kit with upgraded control arms may be recommended to restore factory suspension geometry and improve wheel alignment range.

Yes, this Tough Dog suspension lift kit is specifically engineered for all Toyota Prado 120 Series models manufactured between 2003 and 2009, including both petrol (3.0L and 4.0L V6) and diesel (3.0L D-4D turbo) variants. The kit uses direct OEM replacement mounting points and requires no chassis modifications for fitment. If you have a GX, GXL, Grande, or any other 120 Series trim level within the 2003-2009 model years, this kit will fit your vehicle. For confirmation or specific variant questions, use our online parts finder or contact our technical team with your VIN number.
This Tough Dog lift kit delivers a proven 40mm (approximately 1.6 inches) of lift height across both front and rear axles when measured from factory ride height on an unladen vehicle. Actual lift height may vary slightly depending on your vehicle's existing accessory load, worn factory suspension components, and spring settlement during the initial 500km break-in period. The 40mm lift provides optimal ground clearance for touring and moderate off-road use while maintaining safe suspension geometry and steering angles. This lift height allows fitment of slightly larger tyres (typically up to 265/70R17 or 265/65R18 depending on wheel offset) without rubbing under normal driving conditions.
This complete Tough Dog lift kit includes a full set of four raised coil springs (two front and two rear) engineered to deliver 40mm of lift, plus four shock absorbers with your choice of Foam Cell or Nitro Gas technology matched to the spring rates. All necessary shock mounting hardware, bushings, and U-bolts are included for a complete bolt-in installation. The kit does not include upper control arms, extended brake lines, or differential drop kits, as these are typically not required for a 40mm lift on the Prado 120 platform. Installation instructions and technical specifications are provided with every kit.
Yes, this Tough Dog 40mm lift kit is specifically engineered for towing applications and is an excellent choice for Prado 120 owners who regularly tow caravans, camper trailers, or boat trailers. The heavy-duty raised coil springs are designed to handle increased rear axle loads without excessive sag, maintaining level ride height and safe towing geometry under load. The matched shock absorbers provide excellent damping control to minimise trailer sway and improve stability at highway speeds. For owners who tow variable loads or require fine-tuned ride height adjustment, consider adding airbag suspension as a supplementary load support system while retaining the core benefits of this Tough Dog kit.
Upper control arm upgrades are not typically required for a 40mm lift on the Toyota Prado 120 Series, as this moderate lift height generally remains within acceptable suspension geometry parameters when using factory control arms. However, upgrading to adjustable upper control arms can provide benefits including improved wheel alignment range, restored caster and camber angles for better handling, and the ability to fine-tune your suspension geometry for specific load conditions or tyre sizes. If you plan to fit larger tyres, carry very heavy constant loads, or want optimal on-road handling after lifting, aftermarket control arms are a worthwhile investment. Our technical team can assess your specific setup and recommend whether control arm upgrades would benefit your build.
Yes, a professional four-wheel alignment is absolutely mandatory after installing any suspension lift kit, including this Tough Dog 40mm system for the Prado 120 Series. Lifting your vehicle changes the suspension geometry, affecting camber, caster, and toe angles across all four wheels, which can lead to premature and uneven tyre wear, poor handling characteristics, and reduced braking performance if not corrected. A qualified suspension or alignment specialist should perform a full alignment check and adjustment after installation, ensuring all angles are returned to manufacturer specifications or optimised for your specific load and usage requirements. This alignment should be rechecked after the initial 500km break-in period once springs have fully settled.
This Tough Dog TP12SS1N kit comes with a predetermined spring rate engineered for medium to heavy constant loads, which suits most touring and towing applications on the Prado 120 Series. The spring rates are specifically matched to work with the included shock absorber options (Foam Cell or Nitro Gas) for balanced performance. If you have very specific load requirements — such as particularly heavy constant front-end accessories or extreme rear cargo loads — our technical team can advise on alternative Tough Dog spring options that may better suit your needs. When selecting springs, consider the combined weight of all permanently fitted accessories including bull bars, winches, canopies, drawer systems, long-range tanks, and roof racks to determine your total constant load.
The 40mm lift provided by this Tough Dog kit typically allows fitment of tyres up to 265/70R17 (approximately 31.6 inches diameter) on 17-inch wheels or 265/65R18 on 18-inch wheels, depending on your wheel offset and suspension compression under load. Some light trimming of plastic inner guards or mudflap brackets may be required for full articulation clearance, particularly if running aggressive tread patterns or negative offset wheels. Factory Prado 120 models came with tyres ranging from 245/70R16 to 265/60R18 depending on model year and trim level, so this lift provides meaningful clearance gains. For precise fitment advice based on your specific wheel and tyre combination, consult with our suspension experts who can assess your particular setup and recommend any additional modifications needed for optimal clearance.
This Tough Dog suspension lift kit is backed by the manufacturer's comprehensive Australian warranty, covering defects in materials and workmanship under normal use conditions. Warranty coverage applies when the kit is professionally installed by a qualified technician and the vehicle is used within the suspension's designed load and application parameters. Warranty terms typically cover coil springs and shock absorbers separately, with specific coverage periods and conditions detailed in the documentation provided with your kit. To maintain valid warranty coverage, retain proof of professional installation, ensure correct fitment to the specified vehicle model, and follow all recommended service and inspection intervals. For full warranty details, terms, and claim procedures, contact our team or refer to the Tough Dog warranty documentation included with your purchase.
Absolutely — this Tough Dog 40mm lift kit is engineered to deliver excellent on-road comfort and handling for daily driving, commuting, and highway touring, not just off-road capability. The progressive spring rates and carefully matched shock absorber valving provide a comfortable, controlled ride on sealed roads while still offering the articulation and damping performance needed for gravel tracks and off-road conditions. Many Prado 120 owners choose this kit specifically because it improves daily driving comfort compared to worn factory suspension while providing the additional ground clearance and load capacity needed for weekend adventures and holiday touring. The balanced setup maintains safe highway stability when towing and delivers predictable, confident handling in all conditions from city traffic to remote outback highways.
Proper Kit for Remote Touring Work
Been running this Tough Dog 40mm lift on my 120 Prado for about 18 months now, covering everything from the Canning Stock Route to Cape York wet season tracks. The ride quality loaded up with touring gear is leagues ahead of the factory setup, and the raised coils handle corrugations without the constant bottoming out. Fitment was spot-on with no dramas during installation, and the shocks are still performing perfectly after some serious punishment.(5)
Perfect Upgrade for Our Prado Tourer
Been running this Tough Dog 40mm lift kit on our 120 Prado for six months now, taking the family out to the Flinders and down the coast regularly. The ride quality is genuinely impressive - much more comfortable than stock when loaded up with camping gear and the roof tent. Couldn't be happier with how it handles corrugations and the extra clearance has already saved us a few times on rougher tracks.(5)
Perfect Upgrade for Our Family Tourer
Fitted this Tough Dog lift kit to our 120 Prado about three months ago and it's transformed how the rig handles with the rooftop tent and camping gear loaded up. The ride quality is noticeably better than stock, especially on corrugated dirt roads heading out to our favourite spots along the Murray. Really happy with how level it sits now when we've got the van hitched up for longer trips.(5)
Proper kit for a tradie's daily
Been running this Tough Dog 40mm lift on my 120 Prado for about six months now, carting tools and materials to sites every day. The ride quality is miles better than the old worn suspension it replaced, doesn't sag with a full load anymore. Handled some decent fire trails up the high country last month without any dramas whatsoever.(5)
Sorted My Prado for Serious Remote Work
Had this Tough Dog 40mm lift fitted before heading up the Canning Stock Route and it handled the corrugations and whoops brilliantly. The raised coils give proper clearance for the rocky sections while the shocks soaked up everything without that harsh jarring you get with cheaper setups. Running it loaded with long-range tanks, recovery gear and camp setup, and it's sitting level without any sag. Exactly what you need for genuine outback work.(5)
