Dobinsons offers this complete suspension system with various lift height and coil load options to suit whatever accessory weight you have added to your vehicle, and your desired lift height. Contact Dobinsons directly if you have questions before ordering. Designed, developed and tested in Australia by Dobinsons Spring & Suspension, in-house suspension design engineers, our 4×4 shock absorbers and coil springs are designed and tested to perform in the harshest conditions right across the world. As we 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 and coil spring can withstand the blistering heat and corrugations of the Australian outback right through to the subzero temperatures of a Russian winter. Our Twin Tube Nitrogen Gas charged shock absorbers are made from the world’s highest quality external and internal parts sourced worldwide. They provide a significant increase in performance over the standard shock absorbers. Our twin tube shock absorbers feature larger bodies, larger bores and increased valving performance to dramatically improve vehicle handling and control and reduces shock fade. We proudly manufacture the highest quality replacement coil springs for many different applications, complying to ISO9001:2008 international quality standards from our state of the art manufacturing facility in Central Queensland, Australia. All Dobinsons™ coil springs are load tested and scragged 100% to eliminate subsequent spring sag. We also perform spring fatigue and hardness testing using in-house state of the art testing equipment.
