Where possible 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.
Other hidden design features also include thicker external tube wall thickness up to 3mm on Dobinsons 4×4 struts where other brands use as small as 1.5mm.
Selected Dobinsons 4×4 struts also include single piece drop forged lower mounting stems to provide far superior strength and reliability.
