Toughdog 40mm Suspension Lift Kit for Toyota Prado 150 Series — Complete 4WD Upgrade

This Toughdog kit delivers approximately 40mm (1.6 inches) of lift at both the front and rear of your Prado 150 Series when measured from factory ride height. Actual lift height may vary by 5-10mm depending on your vehicle's existing wear, current accessory load, and selected spring rates. The 40mm lift provides sufficient clearance for tyres up to 265-275mm diameter (approximately 32-33 inches) without requiring major trimming or body modifications. After the initial 500km break-in period, springs will settle slightly and you can expect a final settled height of 35-40mm above factory specifications. This lift height maintains safe suspension geometry and steering angles while significantly improving ground clearance for off-road driving.

This complete kit includes four shock absorbers (two front, two rear) with your choice of foam cell or 40mm bore adjustable technology, two front raised coil springs in your selected load rating (comfort/medium or constant load), two rear raised coil springs in your selected rating (0-300kg or constant 300kg), plus all necessary fitting hardware and installation instructions. You can customise your kit by selecting shock type and spring rates during checkout to match your specific vehicle setup and intended use. The kit provides everything needed for a complete front and rear suspension upgrade. Note that upper control arms, extended brake lines, differential drop brackets, and wheel alignment are not included but may be required depending on your vehicle's configuration and intended lift height.

Yes, this Toughdog kit is specifically engineered to handle towing applications, with rear spring options rated from 0-300kg or constant 300kg to accommodate various towing and payload scenarios. The kit's upgraded spring rates and shock valving reduce rear-end squat when towing, maintaining safer suspension geometry and improving stability at highway speeds. If you frequently tow heavy caravans (2000-3000kg) but don't carry constant rear weight when not towing, we recommend selecting medium rear springs and pairing them with supplementary airbag suspension for on-demand load support without compromising unladen ride quality. The adjustable shock option allows you to fine-tune damping for loaded versus unloaded conditions. Always ensure your towing setup remains within your Prado's rated towing capacity (2500-3000kg depending on model and braked/unbraked configuration).

Upgraded control arms are not mandatory for a 40mm lift on the Prado 150, but they are highly recommended for optimal suspension geometry, particularly if you're running heavy front-end accessories or planning aggressive off-road use. The factory control arms will function with this lift height, but aftermarket extended or adjustable control arms restore correct caster angle, improve steering feel and on-center stability, reduce tyre scrubbing, and enhance suspension articulation on uneven terrain. If you're installing a bull bar, winch, and heavy front accessories, or you notice steering wander or premature inner tyre wear after installation, upgraded control arms will provide noticeable improvements. Our suspension experts can assess your specific setup and recommend whether control arm upgrades would benefit your particular application — contact us for personalised advice.

Yes, a full four-wheel alignment is absolutely mandatory after installing any suspension lift kit, including this Toughdog system. Changing spring and shock components alters your vehicle's suspension geometry, affecting camber, caster, and toe angles beyond factory specifications. Without proper alignment, you'll experience premature and uneven tyre wear (particularly on the inner edges), reduced steering responsiveness, potential pulling to one side, and compromised handling safety. The alignment must be performed by a qualified suspension specialist using calibrated alignment equipment, and should include front and rear axle measurements. We strongly recommend having alignment performed by a shop experienced with lifted 4WD vehicles, as they'll understand the specific geometry requirements for your modified Prado. Budget $150-250 for professional four-wheel alignment as part of your total installation costs.

Spring rate selection should be based exclusively on your constant accessory load — the permanent weight of fitted accessories that your vehicle carries at all times. Calculate front constant load by adding bull bars (40-80kg), winches (30-50kg), upgraded bumpers (60-100kg), and heavy-duty steel bar work. Calculate rear constant load including drawer systems (50-100kg), dual batteries (30-50kg), long-range fuel tanks (empty weight 20-40kg), and permanently mounted camping equipment. Do not factor in occasional loads like passengers, camping gear, water, or towing weight — these temporary loads should not influence base spring selection. If your front constant load is under 50kg, select comfort/medium springs; over 50kg select constant load. For rear springs, under 100kg constant load select 0-300kg springs; over 100kg constant load select constant 300kg springs. Selecting springs rated too heavy for your actual load results in harsh ride quality and potential component damage. Contact our team if you need assistance calculating your specific loads.

With the 40mm lift provided by this Toughdog kit, you can safely fit tyres up to approximately 265/70R17 or 265/75R17 (roughly 32 inches diameter) with minimal to no trimming required, depending on your wheel offset and backspacing. Some owners successfully fit 275/65R18 or 275/70R17 tyres (approximately 33 inches) with minor trimming of inner guard liner and bump stop modifications. Tyre fitment also depends on your wheel specifications — wheels with more positive offset (higher ET number) push tyres inward and may require more trimming, while wheels with more negative offset push tyres outward increasing the risk of guard contact during full lock and articulation. We recommend maintaining factory wheel offset specifications or consulting a wheel fitment specialist before ordering. Always test-fit new tyres at full lock and suspension compression before committing to off-road driving. Remember that larger tyres affect gearing, fuel economy, and speedometer accuracy — recalibration may be required.

This Toughdog suspension lift kit is backed by the manufacturer's comprehensive warranty covering defects in materials and workmanship under normal operating conditions. Warranty periods vary by component type but typically include multi-year coverage on springs and shock absorbers when installed by qualified technicians and used within rated load capacities. Warranty claims require proof of professional installation, evidence of regular maintenance, and adherence to recommended operating conditions. The warranty does not cover damage resulting from collision, overloading beyond rated capacity, improper installation, modified components, competition use, or normal wear items such as bushings and seals after reasonable service life. For specific warranty terms, duration, and claim procedures, refer to the documentation included with your kit or contact Toughdog directly through their official channels. 4WD Suspension Australia will assist with warranty claims and provide support throughout the process.
