Selecting the correct spring rate is critical for optimal ride quality, safety, and suspension longevity. When ordering, choose spring rates based on your current constant load only — this means accessories and equipment permanently fitted to your vehicle. Front constant loads include bull bars, winches, upgraded batteries, long range fuel tanks, and heavy-duty radiators. Rear constant loads include drawer systems, dual battery setups, water tanks, canopies, roof racks with permanent loads, and fixed camping equipment. Do not select spring rates to accommodate occasional loads such as passengers, camping gear loaded for trips, or towing — these temporary loads should be managed with proper packing and airbag suspension if frequent heavy towing is required. Selecting excessively heavy spring rates will result in harsh ride quality on corrugated roads and may cause premature wear or damage to other suspension components.
Professional installation by a qualified 4WD suspension workshop is strongly recommended to ensure correct fitment, torque specifications, and safety compliance. The installation requires specialized tools including torsion bar removal equipment and spring compressors. A full four-wheel alignment is mandatory after installation to restore correct camber, caster, and toe settings — failure to align will result in premature tyre wear and compromised handling. All suspension components require a 500km break-in period during which springs will settle and shock valving will optimize — some initial height loss during this period is normal. Depending on your model year and desired lift height, you may need to pair this kit with upgraded control arms or extended brake lines to maintain factory ride quality and safety standards.

This lift kit is engineered for Toyota 4Runner and Surf owners who demand more from their vehicle — whether you're a grey nomad touring the Outback with a camper trailer, a tradie carrying constant tool loads and equipment, or a weekend warrior seeking better clearance for beach and track access. If you regularly tow caravans or heavy trailers, the increased spring rates and improved shock valving will transform your towing stability and safety. For maximum versatility with varying loads, consider adding airbag suspension to fine-tune your rear suspension on demand without compromising unladen ride quality.

This kit is specifically engineered for Toyota 4Runner and Surf models from 1989-1995 (KZN130 and VZN130 series) that feature coil spring rear suspension combined with front torsion bar suspension. It will not fit earlier models with leaf spring rear ends or later generation 4Runners with different suspension configurations. To confirm exact fitment for your specific year and variant, check your current rear suspension type or contact our technical team with your VIN number. We can verify compatibility and recommend any additional components required for your particular build.
This Tough Dog kit delivers approximately 40-50mm of lift at both the front and rear, depending on your current accessory load and selected spring rates. The actual installed height will vary based on constant weight such as bull bars, winches, drawer systems, and other permanent accessories. Vehicles with heavier constant loads will sit slightly lower than lightly equipped vehicles due to spring compression. After the initial 500km break-in period, expect springs to settle by approximately 10-15mm as they compress and find their optimal operating position under your specific load conditions.
This complete kit includes heavy-duty front and rear Tough Dog shock absorbers, upgraded heavy-duty front torsion bars with increased spring rate, and raised rear coil springs available in multiple load ratings to match your vehicle's constant accessory weight. All necessary mounting hardware and bushings are included for installation. The kit does not include upper control arms, extended brake lines, diff drop brackets, or alignment services — these may be required depending on your specific model year and desired final height. Professional installation is strongly recommended to ensure correct fitment and safety compliance.
Yes, this kit significantly improves towing capability through increased rear spring rates and specially valved shock absorbers that reduce rear-end squat and maintain stability when towing caravans, camper trailers, or boats. The upgraded torsion bars also improve front-end stability and reduce pitching under acceleration when towing heavy loads. However, you must select the correct rear spring rate based on your constant accessory weight — not occasional towing loads. For maximum versatility with varying tow loads, consider adding airbag suspension which allows you to adjust rear height and stiffness on demand without compromising unladen ride quality.
Whether you need upgraded control arms depends on your specific 4Runner/Surf model year and the final lift height achieved. In many cases, the 40-50mm lift provided by this kit can be achieved with factory control arms if they're in good condition, though you may experience slightly altered suspension geometry. However, if you're also fitting larger tyres or seeking maximum articulation for serious off-road use, aftermarket upper control arms with adjustable camber correction will restore optimal geometry and prevent premature tyre wear. Our technical team can assess your specific requirements based on your model year, current suspension condition, and intended use to recommend whether control arm upgrades are necessary for your build.
Yes, a full four-wheel alignment is absolutely mandatory after installing any lift kit and is critical for safety, handling, and tyre longevity. Changing suspension height alters your vehicle's camber, caster, and toe angles from factory specifications, which will cause rapid and uneven tyre wear if not corrected. The alignment must be performed by a workshop with 4WD experience and the capability to adjust all alignment parameters to suit your new suspension height. Skipping or delaying alignment can result in hundreds of dollars in premature tyre replacement and compromised handling characteristics, particularly in emergency braking or evasive maneuvers.
Spring rate selection must be based exclusively on your current constant load — permanent accessories and equipment fitted to your vehicle at all times. Weigh all front constant loads including bull bars, winches, upgraded batteries, long range tanks, and heavy-duty accessories, then select the front spring rate that matches that total weight. Repeat this process for rear constant loads such as drawer systems, dual batteries, water tanks, and permanently mounted equipment. Do not select spring rates to accommodate occasional loads like camping gear, passengers, or towing weight — choosing excessively heavy springs will result in harsh ride quality and potential damage to other suspension components. If you frequently carry varying loads, airbag suspension is a better solution than over-rated springs.
The 40-50mm lift provided by this Tough Dog kit typically allows fitment of tyres up to 31-32 inches in diameter on standard width rims without significant rubbing, though exact clearance depends on your specific tyre width, offset, and wheel choice. For maximum clearance and articulation, you may still need minor trimming of plastic inner guards or mud flaps, particularly if running wider tyres or wheels with aggressive offsets. Always test tyre clearance at full lock and full suspension compression before committing to tyre size, as clearance varies significantly between different tyre brands and tread patterns even at the same nominal size. If you're planning significantly larger tyres, additional modifications such as body lifts or extensive guard trimming may be required.
Tough Dog provides comprehensive manufacturer warranty coverage on all components in this kit, reflecting their confidence in product quality and durability. Specific warranty terms vary by component type — shock absorbers and springs typically carry substantial warranty periods when installed correctly and used within their design parameters. Warranty coverage requires professional installation with proof of service, correct spring rate selection for your actual constant load, and normal operating conditions. Keep all purchase receipts and installation documentation as these will be required for any warranty claims. Contact us for specific warranty duration details for each component in this kit, or refer to the warranty documentation included with your shipment.
Absolutely — Tough Dog engineers every kit to deliver excellent on-road comfort and handling for daily driving while also providing the capability for serious off-road touring. The shock valving is specifically tuned to provide compliant ride quality over urban roads, highway expansion joints, and rough suburban streets, not just off-road tracks. When you select the correct spring rates for your actual constant load, you'll experience ride quality that meets or exceeds factory suspension comfort while adding the ground clearance and load capacity needed for touring and adventure. Thousands of Australian 4WD owners rely on Tough Dog suspension for daily commuting, school runs, and highway travel without compromise, then enjoy the added capability when the weekend adventure begins.
Perfect Upgrade for Our Family Tourer
Fitted this Tough Dog lift kit to our Surf about three months ago and it's been brilliant for our regular camping trips down the coast and out bush. The ride quality is noticeably better than stock, especially when loaded up with the kids' gear and camping equipment. Had it professionally installed and the fitment was spot-on with no dramas, and the bloke at the workshop reckoned it was one of the better kits he's done lately.(5)
Perfect Setup for Full-Time Touring Australia
After 18 months on the road towing our camper trailer from Cape York to the Nullarbor, this Tough Dog lift kit has been absolutely brilliant. The ride quality is leagues better than the worn-out factory suspension we replaced, and it handles our loaded weight plus the van without any dramas. Been through corrugations, river crossings, and everything in between - couldn't be happier with how it's holding up.(5)
Proper Lift Kit That Actually Works
Had this Tough Dog kit fitted to my Surf about six months back and it's been absolutely solid for daily work runs and weekend beach trips. The ride quality is heaps better than the old worn-out stock setup, doesn't bounce around with a load of tools in the back anymore. Fitment was spot on according to my mechanic, saved me a bunch compared to some of the other brands and honestly can't tell the difference.(5)
Perfect Setup for Serious Remote Touring
Been running this Tough Dog lift kit on my Surf for about 8 months now, including a 3-week Cape York trip and multiple Simpson crossings. The ride quality is genuinely impressive – firm enough when loaded with jerry cans and recovery gear, but doesn't beat you to death on corrugations like some budget kits. Fitment was spot-on and the HD torsion bars have held their height perfectly even with the constant punishment of outback tracks.(5)
Perfect upgrade for our family camping rig
Fitted this Tough Dog lift kit to our 4Runner about three months ago and it's completely transformed how the old girl handles with a full load of camping gear and the kids in the back. The ride quality is noticeably smoother on corrugated tracks compared to the worn factory setup, and we're sitting at a nice height now for beach driving without any dramas. Installation was straightforward enough for my local mechanic, and the price was very reasonable compared to some of the other big-name brands I looked at.(5)
