Dobinsons Nitro Gas 2 Inch Lift Kit — Mazda BT50 2012-2020 Complete Suspension Upgrade

This Dobinsons kit provides approximately 50mm (2 inches) of lift at both front and rear axles when measured at the chassis. The actual lift achieved can vary slightly depending on your vehicle's current condition, existing load, and the spring rates you select to match your constant accessory weight. Front lift is achieved through raised coil springs and longer-travel struts, while rear lift comes from the 40mm raised leaf spring pack. After the recommended 500km settling period, you should expect a consistent 45-50mm of additional ground clearance compared to factory ride height. This lift height is ideal for fitting 31-32 inch tyres without rubbing and provides meaningful improvements to approach, departure and ramp-over angles for off-road touring.

This comprehensive kit includes everything needed for a complete front and rear suspension upgrade: 2 Dobinsons Nitro Gas front struts with 35mm bore and 60mm body diameter, 2 heavy-duty front coil springs in your selected load rating, 2 Dobinsons Nitro Gas rear shock absorbers with 32mm bore and 51mm body, 2 x 40mm raised rear leaf spring assemblies in your selected load rating, 4 heavy-duty U-bolts for leaf spring installation, and 1 complete polyurethane bush kit. All necessary mounting hardware and fasteners are included. Please note that upper control arms, extended brake lines, diff drops, and wheel alignment services are not included but may be recommended depending on your vehicle's configuration and intended use.

Yes, this Dobinsons kit significantly improves towing performance compared to factory suspension, particularly when you select the appropriate spring rates to match your constant rear load. The upgraded rear leaf springs and nitrogen gas shock absorbers provide substantially better load control, reduced body roll, and improved stability when towing within your BT50's rated towing capacity. The larger bore shocks resist fade during extended highway towing, maintaining consistent damping even when shock temperatures exceed 100°C. For maximum towing versatility and the ability to adjust ride height based on varying trailer tongue weights, many customers pair this lift kit with supplementary airbag suspension systems that allow on-demand load support adjustment.

While not absolutely mandatory for a 2-inch lift, upgraded adjustable upper control arms are highly recommended to optimize suspension geometry and maximize the benefits of your lift kit investment. A 50mm lift alters your BT50's castor angle, which can affect steering feel, high-speed stability, and accelerate wear on ball joints and CV joints if not corrected. Adjustable control arms allow your installer to dial in the correct castor angle for optimal handling while also providing additional wheel travel for improved off-road articulation. Most professional installers recommend control arm upgrades for lifts over 40mm, particularly if you frequently drive at highway speeds or plan serious off-road touring. Our suspension experts can provide specific recommendations based on your intended vehicle use.

Yes, professional four-wheel alignment is absolutely mandatory after installing any lift kit and should be considered a non-negotiable part of your installation budget. Lifting your BT50 alters all suspension geometry angles including camber, castor, and toe settings at both front and rear axles. Without proper alignment, you will experience accelerated and uneven tyre wear, reduced fuel economy, poor handling characteristics, and potentially unsafe steering behavior at highway speeds. Your installer should perform alignment after the kit is fitted and again after the recommended 500km settling period to ensure all angles are within manufacturer specifications. The cost of alignment is typically $150-250 and is essential to protect your investment in new suspension components and tyres.

Spring rate selection must be based exclusively on your constant accessory load — the permanent weight of accessories installed on your vehicle, not occasional camping gear or towing loads. Calculate your front constant load by adding bull bar weight (typically 25-40kg for steel), winch (30-40kg), driving lights, and upgraded batteries. For the rear, include tray or tub liner (40-80kg), drawer systems (40-80kg), dual batteries, long-range fuel tanks (empty weight), and canopy or hard lid (60-100kg). Select the spring rate that corresponds to your total constant weight in each axle. Choosing springs that are too heavy for your actual load will result in harsh ride quality, reduced traction, and potential damage to other components. If you're between ratings, it's better to choose the lighter spring. Our team can help you calculate exact weights if you're unsure.

This 50mm lift allows you to comfortably fit 31 to 32-inch diameter tyres (approximately 265/70R17 to 285/70R17) on your Mazda BT50 without rubbing under normal driving conditions and moderate wheel articulation. The exact tyre size will depend on your wheel offset, tyre profile, and whether you install wheel spacers or upgraded control arms. Most customers can run 265/70R17 tyres with no trimming required, while 285/70R17 may require minor plastic trimming in the front wheel arch liners during full lock and compression. Going beyond 32 inches typically requires additional modifications including body lifts, significant trimming, and potentially diff gear ratio changes to maintain drivability. Remember that larger tyres affect speedometer accuracy, fuel economy, and powertrain stress — consult with our team about the optimal tyre size for your specific BT50 model and intended use.

Dobinsons backs this complete lift kit with comprehensive manufacturer warranty coverage that reflects their confidence in six decades of engineering expertise and quality manufacturing. Shock absorbers and struts are covered against manufacturing defects, while coil and leaf springs carry warranty against breakage and sagging under normal use conditions when correctly rated for your vehicle's load. Warranty coverage requires professional installation by a qualified mechanic and adherence to recommended service intervals including inspection after the 500km break-in period. Warranty does not cover damage from accidents, misuse, overloading beyond vehicle GVM, or installation of incorrect spring rates for your application. Full warranty terms and conditions are provided with your kit, and our team can answer any specific warranty questions before you purchase.

Absolutely — this Dobinsons Nitro Gas kit is engineered to deliver exceptional daily driving comfort while providing genuine off-road capability when you need it. The vehicle-specific valving is optimized for the BT50's weight distribution to provide controlled, comfortable damping on sealed roads, while the nitrogen gas charge and larger oil capacity prevent fade during highway driving and towing. Many customers report improved ride quality compared to worn factory suspension, particularly when carrying loads, thanks to the progressive spring rates and superior damping control. The natural rubber bushings minimize noise and vibration for refined highway cruising, while the twin-tube design delivers consistent performance across the wide range of speeds and conditions you'll encounter in daily use. This is not a harsh competition kit — it's a premium touring and daily driver upgrade that happens to excel off-road as well.
