Engineered specifically for the PX3 platform, this premium lift kit includes MRA adjustable shocks front and rear, matched coil springs, raised leaf springs, and all mounting hardware. Backed by Dobinsons' legendary Australian engineering, outback testing, and comprehensive warranty — in stock now with fast Australia-wide dispatch.
Dobinsons MRA (Monotube Remote Adjustable) shock absorbers represent the pinnacle of suspension technology for serious 4WD enthusiasts. Born from the winning Monotube Remote Reservoir shocks used in competitive racing, the MRA range combines high-performance monotube design with an advanced 3-way damping adjustment system that transforms your Ford Ranger PX3 into the ultimate touring and off-road machine. The 50mm extra-large bore design, paired with remote oil reservoirs, creates optimal conditions for increased oil capacity and surface area — effectively resisting shock fade and ensuring consistent vehicle handling even under the harshest Australian outback conditions.
The revolutionary 3-way adjustment system provides independent control over high-speed compression, low-speed compression, and rebound damping. High-speed compression damping controls how the shock responds to rapid shaft movements — critical when navigating whoops, corrugations, or sudden vehicle landings on rough terrain. Low-speed compression adjustments directly impact wheel traction, body roll, pitching, diving, and the balance between comfort and performance during everyday driving and gentle off-road work. Rebound damping fine-tunes how quickly the suspension extends after compression, optimizing traction, preventing excessive bounce, and managing your Ranger's pitch, dive, and roll characteristics. This level of tunability means you can set up your shock absorbers perfectly for unladen highway cruising, fully loaded touring with a caravan, or aggressive off-road driving — all with simple adjuster changes accessible without removing the shocks.
The MRA shock design features a newly engineered 6063 honed aluminum reservoir, refined lightweight floating piston, and cutting-edge Carbon Fibre/PTFE/Disulphide composite wear band. Combined with an upgraded 3-stage FKM-HNBR shaft seal mechanism and the ability to operate at lower gas pressures through the reservoir compression adjuster, these innovations dramatically reduce internal friction — translating to noticeably enhanced ride quality and damping performance. The reduced friction not only improves comfort but significantly extends component lifespan by minimizing wear and tear, ensuring top-tier performance in the dust, mud, heat, and corrugation punishment that defines Australian off-road driving.
This complete kit includes Dobinsons front coil springs and rear raised leaf springs specifically engineered and rated for the Ford Ranger PX3 platform. The springs are available in multiple load ratings to match your specific constant accessory load — ensuring optimal ride height, comfort, and handling whether you run a minimal setup or carry heavy touring equipment, bull bars, canopies, drawers, and auxiliary fuel. The polyurethane bush kit and grade 8 U-bolts included in the package ensure secure, squeak-free mounting with excellent durability. Proper spring rate selection is critical: select based only on your constant load (fitted accessories that remain on the vehicle permanently), not occasional loads like passengers, camping gear, or towing loads which are temporary.
The MRA's innovative 3-way design doesn't just offer adjustability — it fundamentally improves thermal performance. By distributing damping workload between the main piston and the reservoir piston, heat generation is spread across a larger oil volume and surface area. This results in lower operating temperatures and dramatically reduced shock fade during extended high-speed gravel runs, long corrugated tracks, or repeated off-road obstacles. Consistent damping performance means predictable vehicle behavior and maintained control even when pushing hard for hours — essential for remote touring and competition use across Australia's demanding terrain.
Every component in the Dobinsons MRA shock absorber has been refined and upgraded to deliver exceptional ride comfort, improved vehicle control, and optimal shock performance. High-quality seals, precision-honed bores, advanced piston designs, and quality shock oil all contribute to the MRA's reputation as one of Australia's finest suspension upgrades. The attention to detail extends to corrosion resistance with hard-anodized components and protective finishes designed to withstand saltwater coastal driving, red dust, and harsh UV exposure.

Selecting the correct spring rate is essential for optimal ride quality, vehicle control, and component longevity. Choose your spring rate based on your constant accessory load only — this means accessories and equipment that remain permanently fitted to your vehicle. Do not factor in occasional loads such as passengers, camping gear, water, fuel, toolboxes, or towing weights when selecting spring rates, as these temporary loads will cause over-springing and result in harsh ride quality and potential damage to other suspension components.
Common Front Constant Loads: Bull bar, winch, driving lights, UHF antenna, auxiliary battery system, upgraded intercooler, air compressor mounted in engine bay.
Common Rear Constant Loads: Canopy or hard lid, aluminium tray, drawer systems, dual battery setup, long range auxiliary fuel tanks, rear bar, dual spare wheel carriers, fixed water tanks, permanently mounted fridges or toolboxes.
If you're unsure which spring rate suits your setup, our suspension specialists can provide guidance based on your specific accessories and typical vehicle use.
Professional installation by an experienced 4WD mechanic or suspension specialist is strongly recommended for this lift kit to ensure correct fitment, torque specifications, and initial damping setup. While experienced DIY installers with proper tools and workshop facilities can complete the installation, precision is critical for safety and performance. A full four-wheel alignment is mandatory after installation to ensure correct castor, camber, and toe settings — improper alignment will cause premature tyre wear, poor handling, and reduced component life.
After installation, a 500km break-in period is recommended where you avoid extreme off-road driving to allow springs to settle and bushings to seat properly. During this period, check all fasteners for correct torque and monitor ride height. Depending on your total lift and intended use, you may benefit from pairing this kit with upgraded control arms to correct front suspension geometry and maximize wheel travel.
The MRA shocks come pre-set to a medium damping setting suitable for most applications. Fine-tuning the 3-way adjusters based on your specific load, driving style, and terrain preferences should be done after the break-in period. Dobinsons provides detailed adjustment guides, and our team can offer setup recommendations for your specific touring or work requirements.

This Dobinsons MRA Adjustable 50mm Lift Kit is specifically engineered for Ford Ranger PX3 (also known as PXIII) models from 2018 to 2022, covering both 2.0L BiTurbo and 3.2L TDCi engine variants. The kit fits all PX3 body styles including single cab, super cab, and dual cab configurations. If you have a significantly modified Ranger or are unsure about your exact model designation, our team can verify compatibility using your VIN or build date. The kit has been designed around the PX3's specific suspension geometry, mounting points, and load characteristics to ensure proper fitment and optimal performance.
This kit delivers approximately 50mm (2-3 inches) of lift height measured at the vehicle's chassis, depending on your specific constant accessory load and spring rate selection. With this lift height and appropriate wheel offset, most PX3 Rangers can accommodate 32-33 inch diameter tyres without rubbing during full suspension compression and steering lock. Actual tyre clearance depends on several factors including wheel offset, tyre width, and whether you've trimmed mudguards or installed aftermarket flares. For aggressive tyre and wheel combinations, you may need additional modifications such as upper control arms or diff drop brackets to maintain proper suspension geometry and maximize clearance.
This complete kit includes everything needed for front and rear suspension: 2 x MRA adjustable front shock absorbers, 2 x Dobinsons front coil springs, 2 x MRA adjustable rear shock absorbers, 2 x Dobinsons raised rear leaf springs, 4 x grade 8 U-bolts, and 1 x polyurethane bush kit. The MRA shocks feature monotube remote reservoir design with 3-way damping adjustment (high-speed compression, low-speed compression, and rebound). Spring rates are selectable during checkout to match your specific constant accessory load. Note that items such as upper control arms, extended brake lines, diff drop brackets, or other chassis components are sold separately and may be required depending on your vehicle's configuration and intended use.
Yes, this Dobinsons MRA kit is excellent for towing when you select the appropriate rear spring rate for your constant rear-end load. The raised leaf springs maintain ride height under towing loads up to 3500kg, while the MRA adjustable shocks allow you to dial in compression damping to control body movement, pitch, and bounce when towing. The 3-way adjustable damping is particularly beneficial for towers — you can soften compression for comfortable unladen driving, then increase both low-speed and high-speed compression damping when hooking up your caravan for improved stability and control. Many customers who tow frequently also add airbag suspension for additional load support and the ability to level the vehicle on-the-fly when loaded.
While upper control arms are not strictly mandatory for a 50mm lift on the Ford Ranger PX3, upgrading to extended upper control arms is highly recommended to correct front suspension geometry and restore proper castor and camber angles after lifting. Lifting without correcting geometry can result in reduced steering returnability, accelerated ball joint and bushing wear, compromised handling, and limited up-travel before components bind. Extended upper control arms allow proper alignment, improve steering feel, increase wheel travel, and prevent premature component wear. If you plan to run larger tyres, do serious off-road work, or want maximum performance from your lifted Ranger, budget for quality upper control arms as part of your suspension upgrade.
Yes, professional four-wheel alignment is absolutely mandatory after installing any lift kit, including this Dobinsons MRA system. Lifting your Ranger changes suspension geometry and alters critical alignment angles including castor, camber, and toe settings at both front and rear axles. Driving without proper alignment after installation will cause rapid and uneven tyre wear, poor handling characteristics, reduced braking performance, and can lead to premature failure of suspension components and steering parts. Ensure your alignment shop has experience with lifted 4WDs and can adjust to specifications appropriate for your new ride height and intended use. Most quality 4WD workshops will include alignment as part of the installation quote.
Spring rate selection should be based solely on your constant accessory load — equipment and accessories that remain permanently fitted to your vehicle. For the front, account for items like bull bars, winches, driving lights, and auxiliary batteries. For the rear, include canopies, drawer systems, dual batteries, auxiliary fuel tanks, rear bars, and spare wheel carriers. Do not include occasional loads such as passengers, camping gear, esky contents, water jerry cans, or towing weight when selecting springs. Selecting springs that are too heavy (over-sprung) will result in harsh ride quality, reduced traction on rough terrain, and potential damage to other components. If you're between two spring rates, generally choose the lighter option unless you're at the upper end of that rating's capacity. Our team can help calculate your constant load if you provide a list of fitted accessories.
With this 50mm lift kit properly installed, most Ford Ranger PX3 vehicles can accommodate 285/70R17 tyres (approximately 32.7 inches diameter) or 265/75R16 (approximately 31.6 inches diameter) with appropriate wheel offset and minimal or no rubbing. Some owners successfully run 285/75R16 (approximately 32.8 inches) with minor trimming of mudguard liners and careful selection of wheel offset. Tyre clearance depends on multiple factors including wheel offset (backspacing), tyre width and profile, whether you've installed upper control arms, and how much upward travel your suspension achieves. Test-fitting is recommended before purchasing expensive tyres and wheels. For aggressive tyre combinations beyond 33 inches or wider than 285mm, additional modifications such as mudguard trimming, aftermarket flares, or further suspension geometry correction may be required.

Absolutely — the Dobinsons MRA Adjustable Lift Kit is an excellent choice for daily driving thanks to its sophisticated 3-way adjustable damping system that allows you to balance comfort and control. When properly set up with the correct spring rates for your load and damping adjusted to a comfortable setting, this kit delivers surprisingly compliant ride quality on highways and urban roads while maintaining excellent body control. The low-friction shock design and monotube technology provide superior small-bump sensitivity compared to traditional twin-tube shocks, resulting in better comfort over patchy roads and minor imperfections. Many owners run softer compression damping settings for daily commuting and weekend highway touring, then dial up the damping when loading up for serious off-road adventures or towing. This versatility makes the MRA kit ideal for Rangers that serve dual duty as weekday work vehicles and weekend adventure rigs.
