Dobinsons Spring and Suspension are proud to announce the long awaited release of the MRA Shocks (MRR 3-way adjustable shock absorbers). These shock absorbers are the culmination of a four-year design, testing and improvement programme undertaken by the Dobinsons Engineering and Design team to build a shock absorber that provides market leading performance, durability and customer tunability.
These are the top of the range Monotube gas shocks that feature:
Available for most popular, larger 4WD models:
Landcruiser • Hilux • Patrol • Ranger
D-Max • Pajero • Prado
Designed, developed and tested in Australia by Dobinsons Spring & Suspension, in house suspension design engineers, Dobinsons 4×4 shock absorbers are designed and tested to perform in the harshest conditions right across the world.
As Dobinsons Spring and Suspension export to over 40 countries worldwide from their Australian head office, the importance of quality is at the forefront in the complete design and manufacturing process. This ensures every shock can withstand the blistering heat and corrugations of the Australian outback right through to the subzero temperatures of a Russian winter.
Regardless of your vehicle choice, Dobinsons has a shock that can transform your ride and handling characteristics for on road vehicles and off road vehicles.
Now available for popular 4WD models with raised suspension kits.
These are a premium product delivered for 4WD vehicles used in tough outback conditions including Cape York, Simpson Desert & Tanami Track style conditions.
They are a monotube gas design with a remote canister to increase performance under hard 4WD conditions.
Technical features include:

And other vehicles coming soon.
The M/T (MonoTubes) are cheaper and more affordable for out clients not needing a unit with remote oil canister (i.e. heavy duty applications)
Simply, the monotube version have the same large internal bore (50 or 60mm) but without the remote canister option.
These are an affordable heavy duty gas shock, ideal for lifts of 2 inches or more on a wide range of 4WD vehicles. Matched with Dobinsons Coil/Leaf Springs to give an excellent ride and super handling.
These are ideal for 3 inch ute lifts and Patrols and Landcruisers with larger lifts (3 – 6 inch). Other popular 4WD fitments include:
It is important to remember that a spring supports weight and sets the vehicle ride height.
It determines the optimum limits of the suspension travel and is a major contributor to the vehicle’s ride and handling.
But a spring cannot operate effectively without a correctly matched shock absorber.
Dobinsons Leaf Springs Feature:
Stringent quality control procedures for Heat Treatment (Tempering) processes at all phases of the manufacturing processes ensures Dobinsons Springs are made the same exceptional way every time.
All leaf lengths are designed and calculated to achieve High Performance spring. Inappropriate leaf lengths will concentrate stress in one particular area and will cause premature sagging or breaking.
To assist in Load Distribution and reduce Inter Leaf Friction which occurs at the end of the leaves.
Where possible, a Military Wrapper is used as a safety mechanism to aid the vehicle’s steering in the case of the main leaf breaking.
Scragging is a process where the spring is load tested to 90% of the Yield Stress of the material used. This process helps to relieve and prevent
sagging.
Reduce friction at the tip of the leaves where the Load is greatest in the spring.
For customers wanting the ultimate raised 50mm leaf springs for:
These are rated for light loads (approx 100KG) and give a comfortable ride, excellent articulation and superior handling on or off road.
Original Equipped Coil Springs are prone to sagging (especially the rear) and therefore cannot satisfactorily carry increased loads.
Dobinsons manufacture after market Coil Springs to restore the ride height with our improved Design Coils. In most cases, the coil is 20% – 40% stronger than the original OEM Spring.
This gives better Load Carrying capacity for Heavy Loads and enhances Road Handling while also improving towing capacities.
Dobinsons Coil Springs Feature:
Design Technology
Dobinsons computers have a design that allows the spring to maximise what is expected of the spring:
Powder Coat Finish
The powder coat finish is baked on to give a lasting protective coat to help eliminate rust.
Formed on Precision Mandrels
Each coil is precisely placed by a programmable logic computer to achieve perfect pitch. This is very important in Variable and Progressive Rate Springs.
Fully Scragged and Load Tested
All coils are scragged 100% to eliminate subsequent spring sag and load tested to ensure that they meet and maintain the required specifications.
Precise End Configurations
Engineered Coil Ends are designed to fit the vehicle correctly.
Shot Peened
Coils are shot peened to give longer life.
State of the Art Heat Treatment
Heat Treatment is unseen and is the most important process in the coil spring manufacturing process. Hardening and tempering is completed by a very accurate electronically controlled furnace to eliminate breakage.
Regardless of your vehicle choice, Dobinsons has a coil that can transform your ride and handling characteristics for on road vehicles and off road vehicles.
Dobinsons have a large range of Coil Springs available and are continuously adding as each new model is released.
