Tough Dog Complete Lift Kit for Mitsubishi Triton MQ MR ML MN — 40-50mm 4WD Suspension Upgrade

This Toughdog lift kit typically provides 40-50mm of lift height depending on your vehicle's current condition, model year, and the spring rates you select to match your constant load. Heavily worn factory suspension may see slightly more initial lift, while newer vehicles with fresh factory components will be at the lower end of this range. Keep in mind that once you load the vehicle with your typical accessories, tools, camping gear, and equipment, the suspension will compress 10-20mm from the unloaded height — this is completely normal and expected behavior. Final installed height is also affected by the 500km settling period, after which the springs stabilize at their working height and may settle an additional 5-10mm as components bed in and bushings take their initial set.

This comprehensive kit includes a pair of heavy-duty foam cell front struts, a pair of progressive rate front raised coil springs, a pair of multi-leaf rear leaf springs designed for enhanced load carrying, a pair of high-performance nitro gas rear shock absorbers with extended travel, a complete rear U-bolt kit with zinc-coated hardware, and a premium polyurethane rear bush kit for long-lasting performance. All necessary mounting hardware is included for the core suspension components. Upper control arms, extended brake lines, diff drop kits, and castor correction bushings are sold separately as they may or may not be required depending on your specific model year, desired lift height, and whether you're running larger tyres — our team can advise on additional components needed for your particular application.

Yes, this Toughdog kit is excellent for towing applications up to 3500kg, delivering significantly improved rear-end stability, reduced body squat under ball weight, and better control during emergency braking and lane changes compared to worn or standard suspension. The heavy-duty rear leaf springs are specifically designed to handle the additional load transfer from towing, maintaining proper suspension geometry and ride height even with heavy caravans or work trailers attached. For maximum versatility and the ability to fine-tune your ride height based on varying trailer weights, consider pairing this lift kit with our airbag suspension systems which allow on-demand adjustment for different towing scenarios. When towing regularly, select rear spring rates based on your typical ball weight (usually 10-15% of trailer weight) plus any constant rear accessories like toolboxes or water tanks.

For lifts in the 40-50mm range provided by this kit, upgraded control arms are not strictly mandatory but are highly recommended for optimizing suspension geometry, maintaining factory-like handling characteristics, and achieving the best possible wheel alignment results. The increased ride height changes the angle of your control arms and ball joints, which can affect steering feel, camber angles, caster angles, and tyre wear patterns if not corrected. If you plan to run larger tyres (265/70R17 or above), regularly drive on extreme off-road terrain with maximum articulation, or want the absolute best handling outcome with improved castor for better highway tracking, upgrading to heavy-duty aftermarket control arms with adjustable geometry correction provides significant benefits. Our suspension specialists can assess your specific requirements including your intended use, tyre size, and budget to recommend whether control arms should be part of your initial upgrade or a future enhancement.

A professional four-wheel alignment is absolutely mandatory after installing any lift kit, including this Toughdog system, and is not optional under any circumstances. Lifting your vehicle changes critical suspension geometry including toe angles, camber angles, and caster angles, which directly affect steering feel, tyre wear patterns, braking stability, and overall handling safety. Without proper post-installation alignment, you will experience premature and uneven tyre wear (particularly on inner or outer edges), steering pull to one side, wandering on the highway, and potentially dangerous handling characteristics during emergency maneuvers. The alignment should be performed after installation but before the 500km break-in period, then rechecked once the springs have fully settled. Some vehicles may require castor correction bushings or adjustable control arms to achieve optimal alignment specifications after lifting — your installer can advise on whether your specific model year requires these additional components.

Yes, one of the key advantages of this Toughdog lift kit is the ability to customize both front and rear spring rates to precisely match your actual constant load, ensuring optimal ride quality and suspension performance for your specific setup. When ordering, you'll select from multiple available spring rates ranging from light recreational use up to heavy constant loads exceeding 400kg in the rear. The correct selection is based only on permanently installed accessories such as canopies, steel trays, drawer systems, dual batteries, long-range fuel tanks (empty weight), water tanks (empty weight), bullbars, winches, and roof rack equipment — not passengers, camping gear you remove between trips, or trailer weight. Our suspension specialists can guide you through the selection process based on your specific accessories, their weights, and distribution between front and rear axles. Choosing the correct spring rate is critical — too soft and you'll experience excessive sag and bottoming out, too stiff and you'll have a harsh, uncomfortable ride that accelerates wear on other components.

This 40-50mm lift kit typically allows you to fit tyres in the 265/70R17 to 275/70R17 range (approximately 31-32 inches diameter) on standard offset wheels without significant rubbing on most Triton models, though some minor trimming of plastic inner guards may be required at full steering lock depending on your specific wheel offset and backspacing. For larger tyres in the 285/70R17 range (approximately 33 inches) or more aggressive tread patterns with larger shoulder blocks, you may require additional modifications including further guard trimming, aftermarket upper control arms to correct geometry, and potentially diff drop kits to maintain CV axle angles. Actual tyre clearance depends heavily on your wheel offset — wheels with more positive offset push tyres outward increasing guard contact, while wheels with appropriate backspacing tuck tyres inward for better clearance. Always test fit new tyres through full steering lock and suspension compression cycles before committing to a wheel and tyre package, and consider that larger, heavier tyres may require recalibration of your speedometer and can affect braking performance.

This Toughdog lift kit is backed by a comprehensive Australian manufacturer's warranty covering defects in materials and workmanship, with specific warranty periods varying by component type — shock absorbers and struts typically carry extended warranty coverage while wear items like bushings have standard coverage reflecting their consumable nature. The warranty is honored through Toughdog's extensive Australian dealer and installer network spanning all states and territories, ensuring you have support and service availability no matter where your travels take you across the country. To maintain valid warranty coverage, keep your proof of purchase and installation records, as professional installation by a qualified mechanic is typically required for warranty claims. The warranty does not cover damage resulting from accidents, improper installation not following manufacturer specifications, unauthorized modifications, racing or competition use, or normal wear and tear from regular use — your installer should provide detailed warranty information and registration procedures at the time of fitment.

Absolutely — this Toughdog kit is specifically engineered to deliver excellent on-road comfort and highway manners while providing enhanced off-road capability when you need it, making it ideal for dual-purpose vehicles used for both daily commuting and weekend adventures. The progressive rate coil springs provide a comfortable ride over small bumps and road imperfections during normal driving, then firm up progressively as load and compression increase during towing, heavy payload carrying, or off-road articulation. The foam cell front struts and nitro gas rear shocks are valved to deliver controlled damping that's not overly firm for empty highway cruising, while preventing excessive body roll, dive under braking, and squat under acceleration when loaded. When correctly matched to your constant load with appropriate spring rates, this kit maintains ride quality very similar to premium factory suspension while dramatically improving load carrying capability, towing stability, and ground clearance. Thousands of Australian Triton owners use Toughdog lift kits daily for work and commuting with excellent results, comfort, and reliability over hundreds of thousands of kilometers.
