Toughdog Rear Coil Springs for Toyota LandCruiser 80 Series — 2-6" Lift

These Toughdog coil springs provide between 2-6 inches of rear lift depending on which spring rate you select and your vehicle's constant load configuration. A lightly loaded 80 Series with minimal accessories will sit at the higher end of the lift range, while a heavily accessorized vehicle with constant rear weight (steel bar, dual spares, long range tank, drawers) will settle lower in the range. The progressive spring design means your actual installed height will vary based on real-world weight — this is normal and ensures the springs are working correctly to support your load. Most touring 80 Series owners achieve 3-4 inches of rear lift with medium to heavy spring rates and typical accessory loads.

This kit includes a pair (2 pieces) of Toughdog heavy-duty rear coil springs with protective powder coating, engineered specifically for the LandCruiser 80 Series rear axle. Installation hardware, spring seats, and shock absorbers are NOT included and must be reused from your existing setup or purchased separately. Front coil springs are sold separately — you'll need to order matching front springs if you want a complete lift kit. We strongly recommend upgrading your shock absorbers at the same time, as factory shocks are typically worn and won't have sufficient travel for lifted springs. A complete suspension upgrade should also include alignment hardware and potentially upgraded control arms for lifts over 2 inches.

Yes, these Toughdog coil springs are engineered to handle occasional towing duties including camper trailers, caravans, boats, and box trailers when you select the appropriate spring rate for your constant accessory load. However, it's critical to understand that towing weight should NOT be factored into your spring rate selection — choose springs based only on permanently fitted accessories, not occasional towing loads. The progressive spring design will compress appropriately when towing to maintain load distribution and ride height. For frequent heavy towing or maximum adjustability, consider pairing these coil springs with airbag suspension which allows you to increase rear support on-demand for towing, then return to comfortable ride height when unloaded.

Control arm upgrades are not mandatory for lifts up to 2 inches, but become highly recommended when lifting your 80 Series beyond 2 inches to maintain correct suspension geometry and alignment capability. Lifting the vehicle changes the angle of your control arms, which can cause castor issues, reduce suspension articulation, accelerate ball joint wear, and make it difficult or impossible to achieve correct wheel alignment settings. Adjustable upper control arms allow your mechanic to restore factory geometry angles and provide sufficient adjustment range for proper alignment after lifting. If you're planning a 3+ inch lift or serious off-road touring, budget for control arm upgrades as part of your suspension build to ensure long-term reliability and optimal handling.

Yes, a full four-wheel alignment is absolutely mandatory after installing these or any replacement coil springs on your LandCruiser 80 Series. Changing ride height alters suspension geometry and affects toe, camber, and castor angles — driving without proper alignment will cause rapid and uneven tyre wear, poor handling characteristics, and potential safety issues. Book your alignment with a reputable 4WD specialist who has experience with lifted vehicles and can verify all angles are within specification. The alignment should be performed after the springs have settled during the initial 500km break-in period for most accurate results. Factor alignment costs ($150-300) into your total suspension upgrade budget.

Spring rate selection must be based exclusively on your constant accessory load — the weight of accessories permanently fitted to your vehicle at all times, not occasional camping gear or towing weight. Common constant rear loads include steel rear bar with swing-away, dual spare wheels, long-range fuel tank, drawer systems, fridge slide, permanently mounted toolboxes, and water tanks. Add up the weight of these items, then select the spring rate that matches your total constant rear accessory weight. Light rating suits minimal accessories (0-50kg constant), Medium suits typical touring setup (50-100kg), Heavy suits extensive accessories (100-150kg), and Extra Heavy suits maximum commercial/expedition loads (150kg+). Choosing springs too heavy for your actual load will result in harsh ride, while too light will cause sagging and bottoming out.

Yes, these coil springs provide 2-6 inches of rear lift which significantly increases clearance for larger tyre fitment on your LandCruiser 80 Series. Most 80 Series owners can fit 33-inch tyres with 2-3 inches of lift and minimal trimming, while 35-inch tyres typically require 4+ inches of lift plus body trimming and potentially wheel spacers or aftermarket wheels with different offset. However, rear lift alone doesn't determine tyre clearance — you'll also need matching front lift and must consider clearance at the firewall, inner guards, control arms, and steering components throughout full suspension articulation. Your actual tyre clearance depends on wheel offset, backspacing, and how much body trimming you're willing to perform. Test fit with full steering lock and suspension compression before committing to expensive tyres.

Toughdog coil springs are backed by the manufacturer's comprehensive warranty which covers defects in materials and workmanship under normal use conditions. The specific warranty period varies by component and application, typically ranging from 12 months to limited lifetime depending on the product line and use case. Warranty coverage requires professional installation, correct spring rate selection for your application, and proper maintenance including regular inspections for damage or fatigue. Warranty does not cover damage from vehicle accidents, incorrect installation, overloading beyond spring rating, or modifications that affect suspension operation. Keep your purchase receipt and installation records to validate warranty claims. Contact 4WD Suspension Australia for specific warranty details on this spring kit and assistance with any warranty-related inquiries.

Absolutely — these Toughdog coil springs are engineered to deliver excellent on-road comfort for daily driving, commuting, and highway touring while providing the strength and travel needed for off-road adventures. The progressive spring rate design means they compress smoothly over bumps and road irregularities, maintaining ride compliance similar to factory springs when correctly matched to your load. However, ride quality is entirely dependent on selecting the correct spring rate — springs that are too heavy for your actual constant load will feel harsh and uncomfortable on-road. When properly specified, most 80 Series owners report ride quality equal to or better than worn factory springs, with the added benefits of increased load capacity, reduced body roll, and maintained ride height under constant accessories. Pair with quality shock absorbers for optimal daily driving comfort.
