Choosing the correct spring rate is critical for optimal ride quality and suspension performance. When ordering this kit, select spring rates based on your constant accessory load — the weight you carry all the time, not occasional loads. Front constant loads include steel bullbars, winches, heavy-duty batteries, and upgraded front bar setups. Rear constant loads include steel rear bars, dual spare wheel carriers, drawer systems, long-range fuel tanks, and permanently fitted water tanks. Do not factor in occasional loads like passengers, camping gear, or items you remove between trips. Selecting spring rates that are too heavy will result in a harsh ride, premature wear on suspension components, and reduced articulation off-road.
Professional installation by a qualified 4WD suspension specialist is strongly recommended for this lift kit. The installation process involves torsion bar indexing, coil spring replacement, shock absorber fitment, and precise adjustment of ride height. A full wheel alignment is mandatory after installation to ensure correct steering geometry, prevent premature tyre wear, and maintain safe handling characteristics. All Toughdog suspension systems require a 500km break-in period during which springs will settle and shocks will bed in — ride height may drop slightly during this period before stabilising. Depending on your final lift height and vehicle load, you may benefit from pairing this kit with upgraded control arms to correct front suspension geometry and maximise CV joint and ball joint lifespan.
Toughdog has earned its reputation as Australia's number one 4WD suspension brand through decades of proven performance in the harshest conditions on earth. Every Toughdog product is designed and tested in Australia for Australian conditions — from the red dust of the Simpson Desert to the salt spray of Cape York and the corrugations of the Gibb River Road. Trusted by professional tourers, tradespeople, and emergency services nationwide, Toughdog suspension delivers unmatched durability backed by comprehensive warranty coverage and local support. Explore the full Toughdog suspension range for complementary upgrades including steering dampers, bushings, and heavy-duty shackles.
This Toughdog lift kit is ideal for Toyota 4Runner and Surf owners who need improved load capacity for touring accessories, better ground clearance for off-road adventures, or enhanced towing stability for caravans and camper trailers. It's the perfect choice for weekend warriors, grey nomads planning a lap of Australia, tradespeople carrying tools and equipment, and families upgrading their touring wagon for remote travel. If you regularly carry heavy rear loads or tow near your vehicle's capacity, consider adding airbag suspension to the rear for on-demand load support and the ability to level your vehicle when towing.

This kit is specifically designed for coil-sprung Toyota 4Runner and Surf models manufactured between 1985 and 2002. It's essential to confirm your vehicle has coil springs at the rear (not leaf springs) before ordering. The kit fits both Japanese domestic market Surf models and Australian/export market 4Runner variants with the coil rear suspension setup. If you're unsure about your vehicle's suspension type, check under the rear of your vehicle or contact our team with your VIN or registration details for confirmation.
This kit typically provides 40-50mm of front lift (via the HD torsion bars) and 40-50mm of rear lift (via the raised coil springs), though actual lift height will vary based on your vehicle's current condition, constant accessory load, and selected spring rates. Vehicles with heavy front accessories like steel bullbars and winches may achieve slightly less lift than unladen vehicles. The torsion bars allow for fine adjustment of front ride height during installation. Final ride height should be assessed after the 500km break-in period when springs have fully settled.
This complete Toughdog lift kit includes front and rear shock absorbers (4 shocks total), two heavy-duty indexed front torsion bars, and two raised rear coil springs with your selected load rating. All components are matched and valved to work together as a complete system. The kit does not include extended brake lines, upper control arms, diff drop brackets, or installation hardware, which may be required depending on your specific vehicle and lift height. Professional installers will assess what additional components are needed during fitment.
Yes, this Toughdog kit is excellent for towing when you select the appropriate rear spring rate for your towing needs. The raised coil springs provide increased load capacity and reduced rear sag compared to worn factory springs, while the revalved rear shocks deliver improved control and stability under tow. When ordering, select a rear spring rate that accounts for your towball download weight as part of your constant load calculation. For maximum towing versatility and the ability to adjust for different trailer weights, consider adding airbag suspension to the rear for on-demand load support.
Upgraded upper control arms are not always essential with a 40-50mm lift but are highly recommended to correct front suspension geometry and maximise the life of CV joints, ball joints, and steering components. The higher your final lift and the more extreme your off-road use, the more beneficial control arm upgrades become. Many experienced 4WD owners install adjustable upper control arms at the same time as their lift kit to dial in perfect castor and camber settings. Our suspension specialists can advise whether control arms are recommended for your specific vehicle setup and driving style.
Yes, a full four-wheel alignment is absolutely mandatory after installing any lift kit, including this Toughdog system. Lifting your vehicle changes suspension geometry, which affects camber, castor, and toe settings — all critical for safe handling, predictable steering response, and even tyre wear. The alignment must be performed by a shop with 4WD experience and the ability to adjust for lifted vehicles. Skipping the alignment will result in premature tyre wear, wandering steering, and potentially dangerous handling characteristics both on and off-road.
Yes, this kit allows you to select spring rates independently for front and rear based on your specific constant load requirements. During checkout, you'll choose front spring rates (based on bullbar, winch, and other front accessories) and rear spring rates (based on rear bar, drawer systems, dual batteries, and long-range tanks) separately. This customisation ensures optimal ride quality and load support for your exact vehicle setup. Be honest about your constant loads and avoid selecting springs that are too stiff, as this results in harsh ride quality and can damage other suspension components over time.
With a 40-50mm lift from this Toughdog kit, most Toyota 4Runner and Surf models can accommodate 31-32 inch diameter tyres (approximately 265/75R16 to 285/75R16) without significant rubbing, though some minor guard trimming may be required depending on wheel offset and backspacing. Tyre fitment also depends on your wheel choice, suspension flex, and whether you've modified guards or bumpers. For larger tyres beyond 32 inches, additional modifications like body lifts, guard cutting, or suspension travel limiting may be necessary. Always test fit with full steering lock and suspension compression before committing to a tyre size.
Toughdog suspension components are backed by the manufacturer's comprehensive warranty, covering defects in materials and workmanship. Warranty periods vary by component type — typically shock absorbers carry a 12-month warranty while springs and torsion bars have longer coverage. Warranty claims require proof of purchase and professional installation with correct fitment procedures followed. The warranty does not cover damage from accident, misuse, overloading beyond vehicle specifications, or wear and tear from normal use. Keep your purchase receipt and installation documentation for warranty purposes.
Absolutely — this Toughdog kit is designed to deliver excellent ride quality for daily driving while providing enhanced capability for touring and off-road use. When you select spring rates correctly matched to your constant load, the system provides a comfortable, controlled ride on sealed roads, highways, and urban driving. Toughdog's foam cell shock technology prevents fade during highway use and delivers consistent damping performance. The suspension strikes an excellent balance between load-carrying capability and everyday comfort, making it ideal for vehicles that serve as both daily drivers and weekend adventure rigs.
Solid Kit for Daily Work Duties
Been running this Toughdog lift kit on my Surf for about six months now, carting tools and materials to job sites every day. The ride quality is surprisingly comfortable even with a full load, and it handled the beach tracks down the coast over Christmas without any dramas. Installation was straightforward enough and everything lined up properly. Good value for a complete kit that actually does what it's supposed to.(5)
Perfect for the High Country and Beyond
Been running this Toughdog lift kit on my Surf for about 8 months now, covering everything from the Canning Stock Route to Victorian High Country tracks. The ride quality is genuinely impressive – loaded up with recovery gear, water, and camping equipment, it sits level and handles corrugations far better than the old setup. Fitment was spot-on and the increased clearance has already saved me from a few dodgy creek crossings that would've been sketchy before.(5)
Perfect Setup for Our Family Adventures
Had this Toughdog lift kit fitted to our '98 Surf about three months back and it's been fantastic for our monthly trips down to the South Coast. The ride quality is noticeably smoother than the old setup, even when we're loaded up with the camper trailer and all the kids' gear. Really impressed with how it handles corrugations on dirt roads now – the family actually enjoys the drive instead of complaining about being rattled around.(5)
