Twin Tube Nitro-Gas

Dobinsons Twin Tube Nitro-Gas shocks are the perfect upgrade for 4x4 enthusiasts who demand the highest quality suspension components. Designed, developed, and tested in Australia by Dobinsons Spring & Suspension's in-house suspension design engineers, these shock absorbers are built to perform in the harshest conditions around the world.

With a commitment to quality, Dobinsons Spring and Suspension exports to over 40 countries worldwide from their Australian head office. Every shock absorber is designed and manufactured to withstand the extreme conditions of the Australian outback to the subzero temperatures of a Russian winter.

Dobinsons design each part number to provide a longer shock absorber for more wheel travel, firmer valving for a more controlled ride, and a larger body with increased oil capacity for cooler operation than the original vehicle shock absorbers.

The Dobinsons Twin Tube Nitro-Gas shocks feature a big-bore twin-tube design, nitrogen gas charged, superior design, high-quality parts, and manufacturing processes. These shocks have a direct bolt-in OE replacement, a 35mm & 32mm bore size, double chromed 18mm rod, 60mm & 51mm body size, high-quality Fuch's oil, NOK multi-lip seals, Teflon piston rings, and natural rubber bushings.

In addition to these features, selected Dobinsons 4x4 struts also include single piece drop-forged lower mounting stems to provide far superior strength and reliability. With a thicker external tube wall thickness of up to 3mm, Dobinsons Twin Tube Nitro-Gas shocks offer better durability than other brands that use as small as 1.5mm.

Upgrade your 4x4 suspension with Dobinsons Twin Tube Nitro-Gas shocks for a smoother, more controlled ride. Choose the best, choose Dobinsons.
