Not sure if this fits your vehicle or which spring rate is right for your load? Contact our suspension experts or check our FAQ page for personalized advice.
Selecting the correct spring rate is critical for achieving optimal ride quality, load capacity, and component longevity. Your spring rate should be based on the constant load you carry in your vehicle — this means accessories and equipment permanently installed, not occasional cargo or passengers. Common rear constant loads include steel canopies, aluminium trays, toolboxes, dual battery systems, water tanks, drawer systems, roof racks, spare wheels, and long-range fuel tanks. Occasional loads such as camping gear, towing, firewood, or temporary cargo should NOT be factored into your spring rate selection — choosing springs that are too heavy will result in a harsh, uncomfortable ride and may cause premature wear to other suspension components. If you frequently tow heavy trailers or caravans, consider pairing your leaf springs with adjustable airbag suspension for variable load support without compromising daily ride quality.
Professional installation by a qualified mechanic or experienced 4WD workshop is strongly recommended to ensure correct fitment, torque specifications, and suspension geometry. Wheel alignment is mandatory after installation to prevent premature tyre wear and maintain proper handling characteristics. A 500km break-in period is required for new leaf springs to settle and reach optimal performance — avoid maximum loads during this initial period. For vehicles fitted with aftermarket accessories or requiring additional lift height, consider upgrading to extended rear shock absorbers to maintain correct suspension travel and prevent shock bottoming under compression.
Toughdog has earned its reputation as Australia's most trusted 4WD suspension brand through decades of engineering excellence, real-world outback testing, and unwavering commitment to quality.

Yes, these Toughdog rear leaf springs are engineered specifically for Holden Rodeo KB series models produced between 1981 and 1988, covering both 2WD and 4WD variants. They are designed as direct OEM replacement springs with bolt-in fitment using factory mounting points and hardware locations. The springs maintain correct spring eye spacing and centre bolt positioning for proper alignment with your vehicle's chassis and axle mounting points. If you have made modifications to your vehicle's rear suspension or chassis, or if you're unsure about your exact model year or variant, we recommend contacting our team to confirm fitment before ordering.
These Toughdog rear leaf springs are primarily designed as replacement springs to restore original ride height and increase load capacity, rather than dedicated lift springs. If your factory springs have sagged over time due to age or constant loading, these springs will restore your Rodeo's rear end to its correct factory height specification, which may appear as a "lift" compared to your current worn springs. The actual height restoration will depend on the condition of your existing springs and the spring rate you select based on your constant load requirements. For specific lift height requirements or levelling your vehicle when carrying heavy accessories, our suspension specialists can recommend the appropriate spring rate or alternative lift spring options.
This kit includes a pair (left and right) of Toughdog heavy-duty rear leaf springs with centre bolts, spring eye bushes for both front and rear mounting points, spring shackles and pins, and protective corrosion-resistant coating. The springs come with installation instructions and spring rate selection guidance to help you choose the correct load rating for your application. Please note that U-bolts and some mounting hardware may be sold separately depending on your specific vehicle configuration and whether you're reusing existing hardware. We recommend inspecting all mounting hardware during installation and replacing any worn or damaged components for optimal safety and performance.
Yes, Toughdog rear leaf springs significantly improve towing performance by reducing rear squat, maintaining level vehicle attitude, and increasing rear axle load capacity when properly matched to your constant load requirements. However, it's critical to select your spring rate based on your permanent accessory weight only — not towing loads. For optimal towing performance with variable trailer weights, we strongly recommend pairing your new leaf springs with an adjustable airbag suspension system that allows you to increase rear support when towing and reduce it for improved ride quality when driving unloaded. This combination provides the best balance of daily comfort, load capacity, and towing stability for recreational and commercial applications.
While not strictly mandatory, upgrading your rear shock absorbers when installing new leaf springs is highly recommended for optimal performance, ride quality, and component longevity. New leaf springs will restore suspension travel and load capacity, which means your existing worn shocks may no longer provide adequate damping control, leading to bouncing, poor handling, and premature spring wear. Fresh springs paired with worn shocks create an unbalanced suspension system that cannot perform to its full potential. Consider upgrading to Toughdog foam cell or gas shock absorbers designed specifically for your Rodeo to maximize comfort, control, and off-road capability while protecting your investment in new leaf springs.
Yes, a full four-wheel alignment is mandatory after installing new rear leaf springs to ensure correct suspension geometry, prevent premature tyre wear, and maintain safe handling characteristics. New springs will change your vehicle's rear ride height and axle positioning, which affects camber, toe, and thrust angle measurements that must be corrected through professional alignment. Skipping this critical step can result in uneven tyre wear, reduced fuel economy, poor steering response, and unsafe handling dynamics, especially when loaded or towing. Any reputable 4WD workshop or suspension specialist will include alignment as part of their installation service, and alignment costs should be factored into your total upgrade budget.
Spring rate selection should be based exclusively on your constant load — permanent accessories and equipment installed in or on your vehicle at all times. For your Holden Rodeo, this includes items like steel or aluminium canopies, toolboxes, drawer systems, dual battery setups, water tanks, roof racks, and any other fixed equipment. Add up the total weight of these constant accessories, then select the spring rate closest to that load specification. Do not include occasional cargo, passengers, camping gear, or towing loads in your calculation, as choosing springs that are too stiff will result in harsh ride quality and potential damage to other suspension components. Our team can provide personalized spring rate recommendations based on your specific setup and usage requirements.
These Toughdog rear leaf springs are designed primarily as replacement springs rather than lift springs, so they will restore your vehicle to factory ride height specifications rather than providing additional clearance for larger tyres. If your factory springs have sagged significantly, the height restoration may provide marginally improved clearance, but this should not be relied upon for tyre size increases. For fitting larger diameter or wider tyres, you would need a dedicated suspension lift kit that includes taller springs, extended shocks, and potentially modified suspension geometry components. If tyre clearance and lift height are your primary goals, contact our suspension specialists to discuss complete lift kit options suitable for your Rodeo model and intended tyre size.
Toughdog rear leaf springs are backed by the manufacturer's comprehensive warranty covering defects in materials and workmanship under normal use conditions. Warranty duration and specific terms are detailed in the documentation included with your springs and vary based on application type (recreational vs commercial use). To maintain valid warranty coverage, springs must be professionally installed according to manufacturer specifications, used with appropriate constant load ratings, and paired with functional shock absorbers. Warranty claims require proof of purchase and installation by a qualified mechanic or workshop. For complete warranty details, terms, and conditions specific to this product, please refer to the included documentation or contact our customer service team.
Absolutely — when correctly matched to your constant load requirements, Toughdog rear leaf springs provide excellent daily driving comfort, responsive handling, and long-term durability for both urban commuting and highway touring. Unlike budget replacement springs that may be too soft (causing sag) or too stiff (causing harsh ride), Toughdog's precision-engineered leaf profile and progressive spring rate design deliver balanced performance across varying road conditions. The key to comfortable daily driving is selecting the appropriate spring rate — choosing springs matched to your actual constant load rather than overspecifying for occasional heavy loads. For drivers who need variable load support for weekend activities or occasional towing, pairing properly rated leaf springs with supplemental airbag suspension provides the best combination of daily comfort and weekend capability.
