Selecting the correct spring rate is critical for achieving optimal ride quality and preventing premature wear. When ordering, choose your spring rate based on your constant accessory load only - this means permanent weight carried in your vehicle 90% of the time. Common rear constant loads include steel canopies (70-120kg), aluminium toolboxes (30-50kg), dual battery systems (20-30kg), water tanks (when full), drawer systems (40-80kg), and roof racks with permanent accessories. Do not factor in occasional loads like camping gear, passengers, or towing - selecting springs too stiff for your actual constant load will result in a harsh ride and potential damage to other suspension components. If you're unsure about your total accessory weight, our suspension specialists can help you calculate the correct spring rate for your specific setup.
Professional installation by a qualified mechanic or experienced 4WD workshop is strongly recommended for leaf spring replacement. The installation process requires specialized spring compressors, torque wrenches, and proper safety equipment. A full four-wheel alignment is mandatory after fitting to ensure correct camber, caster and toe settings - failure to align can cause uneven tyre wear and compromised handling. We recommend a 500km break-in period where you avoid extreme off-road driving and heavy loads, allowing the springs to settle and bushings to seat properly. For Triton MV owners lifting the rear, pairing these springs with upgraded control arms at the front maintains balanced handling and prevents uneven ride height.
Toughdog has earned its reputation as Australia's number one suspension brand through decades of real-world testing across the harshest outback conditions. Every Toughdog component is engineered specifically for Australian vehicles and driving conditions, from corrugated desert tracks to beach sand and rocky mountain trails. Trusted by tradespeople, grey nomads, and serious off-road tourers, Toughdog delivers the perfect balance of load-carrying capability, ride comfort, and bulletproof reliability. Explore the complete Toughdog suspension range for matched shocks, springs and complete lift kits designed to work together seamlessly.
These Toughdog rear leaf springs are ideal for Triton MV owners who have added permanent accessories and need improved load support without sacrificing daily driving comfort. Tradespeople carrying heavy toolboxes and equipment, weekend warriors with permanent canopy and camping setups, and caravan towers experiencing rear squat will all benefit from the enhanced spring rates and durability. For those who regularly carry variable loads or tow different weight trailers, consider pairing these springs with airbag suspension for on-demand adjustability without changing spring rates. Whether you're commuting during the week or exploring remote tracks on weekends, these springs deliver consistent performance across all conditions.

These Toughdog rear leaf springs are specifically engineered to fit all Mitsubishi Triton MV series models from 2015 to 2018, including single cab, dual cab, and club cab body styles. They are direct OEM replacements that use the original mounting points without requiring any drilling or modifications. If you have a different Triton generation (ML, MN, MQ, MR) these springs will not fit - please check our parts finder to locate the correct springs for your specific model year. For confirmation of fitment or if you're unsure of your vehicle's series code, contact our team with your VIN number.
Toughdog rear leaf springs are primarily designed for load support and ride quality improvement rather than significant lift height. Depending on your selected spring rate and constant accessory load, you can expect between 0-25mm of additional rear height compared to worn factory springs. The actual lift achieved varies based on your vehicle's current spring condition and the weight you're carrying - heavier constant loads will compress the springs closer to standard height. If you're looking for significant lift for larger tyres, consider a complete suspension lift kit that includes matched front and rear components. These springs focus on restoring or slightly improving ride height while dramatically enhancing load-carrying capability.
This kit includes two heavy-duty rear leaf springs with integrated bushes, centre bolts, and comprehensive fitting instructions. U-bolts are sold separately as they are vehicle-specific and depend on your axle configuration and any modifications. Shock absorbers are also not included - we strongly recommend replacing or upgrading your rear shocks when installing new leaf springs to achieve optimal ride quality and handling. The springs come with anti-corrosion powder coating and inter-leaf friction pads pre-installed. All necessary hardware for attaching the springs to your factory mounting points is included, making this a straightforward replacement for experienced installers.
Yes, when correctly rated for your constant load, these Toughdog leaf springs significantly improve towing performance by reducing rear squat and maintaining proper vehicle geometry. They help keep your Triton level when hitched to caravans or trailers, which improves steering response, headlight aim, and overall stability. However, it's crucial to select springs based on your constant accessory load only - not your occasional towing weight. For maximum versatility with varying trailer weights, consider supplementing these springs with airbag suspension, which allows you to adjust support on-demand. Always ensure your total vehicle and trailer combination stays within the manufacturer's GVM and GCM ratings regardless of suspension upgrades.
While these leaf springs are direct replacements that don't require other upgrades, we strongly recommend replacing your rear shock absorbers at the same time for optimal performance. New springs with worn shocks will not deliver the ride quality and control you're expecting - matched Toughdog shocks are engineered to complement these spring rates perfectly. If you're also lifting the front of your Triton, extended-length shocks may be required to accommodate increased travel. U-bolts should always be replaced when removing leaf springs, as reusing old U-bolts can compromise clamping force and safety. For vehicles with significant front lift, extended brake lines and differential drop kits may also be necessary to maintain proper geometry.
Yes, a full four-wheel alignment is absolutely mandatory after installing new rear leaf springs. While rear leaf springs don't typically affect toe settings as dramatically as front suspension modifications, any change in ride height alters your vehicle's suspension geometry, including pinion angle and overall stance. Proper alignment ensures even tyre wear, optimal handling characteristics, and prevents steering pull. The alignment should be performed after the springs have settled under your normal constant load and after the initial 500km break-in period. Skipping the alignment can lead to premature tyre wear costing hundreds of dollars and potentially compromised handling in emergency situations.
Yes, Toughdog leaf springs are available in multiple spring rates to match your specific constant load requirements. When ordering, you'll select your spring rate based on the permanent weight carried in your vehicle - this includes items like canopies, toolboxes, drawer systems, dual batteries, and water tanks when full. It's critical to be honest about your constant load and not overestimate by including occasional camping gear or passenger weight. Selecting springs that are too stiff for your actual load will result in a harsh, uncomfortable ride and can cause excessive wear on other suspension components. Our team can help you calculate your constant accessory weight and recommend the ideal spring rate for your specific Triton setup.
These rear leaf springs alone provide minimal lift (0-25mm) and are not designed as a tyre clearance solution. While they may provide slightly more clearance than worn factory springs, you will not achieve sufficient height for significantly larger tyres without a complete front and rear lift kit. For the Triton MV, most owners can fit up to 265/70R17 or 265/65R18 tyres with minimal modifications on the standard suspension height. If your goal is to run 32-inch or 33-inch tyres, you'll need a comprehensive lift kit that includes front coil springs or strut spacers, matched shocks, and potentially diff drop brackets. These leaf springs work perfectly as the rear component of a complete lift system when paired with appropriate front lift components.
Toughdog leaf springs are backed by the manufacturer's comprehensive warranty covering defects in materials and workmanship. The specific warranty period varies by component, but Toughdog typically offers multi-year coverage on their spring products. Warranty claims require proof of purchase and professional installation, and coverage may be void if springs are installed with incorrect spring rates for your actual load or if vehicle modifications exceed manufacturer specifications. The warranty covers manufacturing defects but does not cover normal wear, damage from accidents, or issues arising from improper installation. Keep your invoice and installation records, and register your purchase with Toughdog for full warranty protection and support.
Absolutely - when correctly rated for your constant load, these Toughdog leaf springs deliver excellent ride quality for daily driving while providing the extra support needed for weekend adventures. Toughdog's progressive spring rate design means they're compliant and comfortable when unladen or lightly loaded, but progressively stiffen as weight increases. This gives you the best of both worlds: a composed ride for the daily commute and confident load-carrying for touring or work. However, if you select springs rated too high for your actual constant load, they will ride harshly when empty. Be honest about your permanent accessory weight and choose the appropriate spring rate - your back will thank you on those long highway drives to your favourite camping destinations.
