Selecting the correct spring rate is critical for ride quality, handling and component longevity. Your spring rate should match your vehicle's constant load — the combined weight of accessories permanently fitted to your Prado. Occasional loads such as camping gear, passengers, or periodic towing should NOT be factored into spring rate selection, as over-sprung suspension results in harsh ride quality and accelerated wear on bushings, shocks and other components.
Common rear constant load items include: rear drawer systems, dual battery setups, long-range fuel tanks, water tanks, fixed storage systems, permanent cargo barriers, aftermarket spare wheel carriers, upgraded rear bumpers, and heavy-duty tow bars. Calculate the total weight of these permanently installed accessories and select the appropriate spring rate during checkout. If your constant load changes significantly in future, spring rate can be upgraded separately.
Professional installation by a qualified mechanic or experienced DIY installer with appropriate equipment is strongly recommended. Spring compressors are mandatory for safe coil spring removal and installation, and incorrect procedure can result in serious injury. A wheel alignment is essential after fitting new coil springs to ensure correct suspension geometry, prevent premature tyre wear, and maintain steering precision. During the first 500km break-in period, springs will settle approximately 10-15mm as the steel heat treatment stabilizes under load.
For vehicles with significant front-to-rear height difference after installing rear springs, or for more comprehensive suspension upgrades, consider pairing with front coil springs, upgraded shock absorbers, and uprated control arms for balanced geometry and optimal performance.

Yes, these Toughdog rear coil springs are specifically engineered for all Toyota Prado 120 Series variants manufactured between 2002 and 2009, including GX, GXL, and Grande models. They're designed as direct OEM replacements with correct spring diameter, seat dimensions, and mounting specifications. The springs fit both petrol and diesel engine variants without modification. If you have specific fitment concerns about your particular Prado configuration or have already modified your suspension, our technical team can verify compatibility before purchase.
These Toughdog rear coil springs are primarily designed for load compensation and ride height restoration rather than aggressive lift. They will restore factory ride height if your vehicle has sagged due to accessory weight or aging springs, and may provide 0-25mm of additional height depending on your selected spring rate and constant load. The actual lift achieved varies based on spring rate selection, existing rear load, and front suspension configuration. For significant lift applications, these rear springs should be paired with appropriate front coil springs as part of a complete lift kit for balanced suspension geometry.
This kit includes two heavy-duty Toughdog rear coil springs manufactured from high-tensile spring steel with corrosion-resistant powder coat finish. The springs feature progressive wind design and are available in multiple load-specific spring rates to suit your vehicle's constant accessory weight. Spring compressors, installation hardware, and shock absorbers are not included and must be purchased separately if required. The springs are compatible with your existing spring seats, isolators, and mounting hardware, though we recommend inspecting these components during installation and replacing if worn.
Yes, when correctly rated for your constant load, these Toughdog rear coil springs significantly improve towing performance by reducing rear-end squat and maintaining proper suspension geometry under drawbar weight. However, it's crucial to select spring rate based on your permanent accessory weight only — not occasional towing loads. For vehicles that tow intermittently or with varying trailer weights, we strongly recommend supplementing constant-load rated springs with airbag suspension, which provides adjustable load support you can inflate when towing and deflate for comfortable daily driving. This combination delivers the best of both worlds without over-springing your suspension.
Rear control arm upgrades are not mandatory when fitting replacement coil springs at stock or near-stock height, as the Prado 120 Series rear suspension geometry remains within acceptable tolerances. However, if you're installing these springs as part of a broader suspension lift that includes front height increase, or if your existing control arms show wear in bushings or ball joints, upgrading to heavy-duty adjustable control arms is highly recommended. Upgraded control arms allow precise geometry correction, reduce caster wind-back under load, and provide superior articulation for off-road driving. Our suspension specialists can assess your complete setup and recommend appropriate upgrades.
Yes, a full four-wheel alignment is absolutely essential after installing new rear coil springs on your Prado 120 Series. Any change to ride height affects suspension geometry including toe, camber, and thrust angle, which directly impacts tyre wear patterns, steering precision, and vehicle stability. Professional alignment ensures your suspension operates at correct angles, prevents premature and uneven tyre wear, and maintains safe handling characteristics. Most reputable suspension installers include alignment in their fitting service. Skipping alignment to save costs will result in far greater expense through accelerated tyre replacement and potential handling issues.
Absolutely — Toughdog manufactures these Prado 120 Series rear springs in multiple load-specific spring rates to precisely match your vehicle's constant accessory weight. During checkout, you'll select the appropriate spring rate based on the combined weight of permanently installed rear accessories such as drawer systems, dual batteries, long-range tanks, and tow bars. It's critical to be honest about your actual constant load and not select heavier springs to accommodate occasional camping gear or towing, as over-sprung suspension delivers harsh ride quality and accelerates wear on shocks and bushings. Our team can help calculate your constant load if you're unsure which rate to select.
These rear coil springs primarily address load capacity and ride height restoration rather than providing significant lift for tyre clearance. While they may provide 0-25mm of additional height depending on spring rate and load, this modest increase won't substantially change your tyre clearance in the rear guards. The Prado 120 Series can typically accommodate 265/70R17 or 265/65R18 tyres with minimal modification at stock height. For larger aggressive tread patterns or significant diameter increases, you'll need a complete suspension lift kit including front height increase, and potentially wheel spacers or aftermarket guards. Our technical team can advise on the maximum tyre size for your specific suspension configuration.
Toughdog rear coil springs are backed by the manufacturer's comprehensive Australian warranty covering defects in materials and workmanship. This warranty protection reflects Toughdog's confidence in their engineering quality and manufacturing standards. Warranty coverage requires springs to be professionally installed and used within their design specifications, including correct spring rate selection for your vehicle's constant load. Warranty does not cover damage from incorrect installation, vehicle accident, overloading beyond spring rating, or normal wear from extended use. Retain your purchase receipt and installation documentation for warranty claims. Full warranty terms are available from our customer service team.
Yes, when correctly rated for your constant accessory load, these Toughdog rear coil springs deliver excellent daily driving comfort while providing the load capacity and durability required for touring and work applications. The progressive wind design ensures comfortable ride quality when unladen, with spring rate progressively increasing under load for stability and control. However, selecting spring rates heavier than your actual constant load will result in harsh, uncomfortable ride quality for daily commuting. Be honest about your permanent accessory weight during spring rate selection — if you only load heavy gear occasionally, choose springs for your everyday weight and consider supplementary airbags for periodic heavy loads.
