Please note: All suspension lift kits will come with recommended constant load springs to suit the vehicle. Refer to PDF for available options to suit the weight of accessories fitted to the vehicle.
Built on Pride, Developed with Technology
Dobinsons manufactures and repairs a large range of springs and sells a comprehensive range of suspension components for 4×4 Vehicles. Dobinsons stocks 13,000 spring and suspension specifications on hand, these recommendations should be used as a guide only and more consultation should be given.
Dobinsons Spring and Suspension™ proudly manufacture the highest quality replacement coil springs for many different applications to ISO9001:2008 international quality standards from their state of the art manufacturing facility in Central Queensland, Australia. Dobinsons™ proudly boast one of the world’s largest range of coil springs including raised height and heavy duty 4wd springs, lowered performance passenger car springs, O.E. replacement springs and heavy duty springs for commercial vehicles.
As Dobinsons™ coil springs are manufactured in house, Dobinsons™ can manufacture smaller quantities and in most cases there are many different coil spring options available for your vehicle. This ensures the customer receives the best spring to suit their application and avoids a “One Size Fits All” scenario, especially important when selecting the correct spring rates and ride heights. When matched with a set of corresponding Dobinsons™ Heavy Duty Gas Shock Absorbers, Dobinsons™ can provide you with unrivalled performance and handling.
Spring Design engineers within Dobinsons Spring & Suspension™ utilise the latest coil spring design programs to ensure each spring will meet and exceed the design requirements and achieve the maximum working life. These state of the art design programs are crucial when designing variable/progressive rate springs to ensure laden and unladen spring rates are correct to provide the best possible ride comfort and handling.
Heat treatment is one of the most important steps in the coil spring manufacturing process. All Dobinsons coil springs are ‘hot wound’ and the hardening and tempering of our coil springs is completed by an extremely precise electronically controlled furnace to eliminate breakage and sagging.
Each coil spring is precisely wound by a programmable logic computer to achieve perfect pitch. This precision is extremely important when manufacturing variable and progressive rate coil springs. All Dobinsons™ coils springs are shot peened to increase durability and dramatically reduce fatigue.
Engineered coil ends are designed to fit directly into the original vehicle mounting points without any modification. All Dobinsons™ coil springs are load tested and scragged 100% to eliminate subsequent spring sag, and ensure they meet and maintain the required specifications. We also perform spring fatigue and hardness testing using in-house state of the art testing equipment.
A durable powdercoat finish provides extreme protection against the elements.
Dobinsons IMS monotube shock absorbers are designed for next level performance over twin tube shocks in those hot, harsh, demanding conditions. By utilising the monotube design, Dobinsons IMS shock absorbers are able to resist fade far longer on corrugated roads, long or hard working 4WD trips, towing or racing conditions.
The larger 50 and 60mm high flow pistons reduce internal pressures, reduce the heat generated, transfer heat to the body for faster cooling and offer improved damping performance and vehicle control at higher shaft speeds on rough terrain and during big impacts. Threaded bodies on struts allow for fine tuning of height and offer further improvements in cooling. The micropolished, hard chromed and heat treat shock shaft, CNC aluminium high flow race inspired piston, and DOM seamless tubing body provides the ultimate in performance and off-road durability.
Composite piston wear bands, high quality Fuchs oil and a race style 3-stage sealing system offer the lowest levels of friction whilst maintaining durability and longevity without the need for frequent rebuilding or servicing. Dobinsons team of engineers spend hundreds of hours of testing and tuning the shim stacks and damping Characteristics in each IMS shock to ensure a balance of comfort, handling, vehicle control and off-road performance - Enjoy the ride

Dobinsons new range of MRR Adjustable shock absorbers combine the best in high performance race-bred Monotube technology, with an all new 3-way damping adjustment system to turn your 4x4 into the ultimate off-road machine. Each component of the MRR shock absorber has been refined and improved to offer a higher level of ride quality, vehicle control and shock absorber performance.
The new 6063 honed aluminium reservoir, revised light-weight floating piston, Carbon Fibre/PTFE/Disulphide composite wear band, improved 3-stage sealing system and the ability to run lower gas pressure with the addition of the reservoir compression adjuster, have combined to provide massive reductions in shock absorber friction, resulting in an improved vehicle ride and damping performance. The revised sealing design now provides a 3 stage FKM-HNBR shaft seal system that, when combined with the reduced operating frictions, provides a vastly increased service life with reduced wear.
The Micro-polished, hard chromed and heat treated shock shaft, revised CNC aluminium high flow race piston, and DOM Seamless tubing body provides the ultimate in performance and off-road durability. The 3-way adjustment design reduces the main piston working load, distributing heat more evenly between the main piston and the reservoir piston for reduced operating temperatures, and allows quick and easy damping changes for the ultimate in shock tunability in varying terrain and vehicle loads, to keep you controlled and comfortable.
