3.0 Series shocks boast 50% more piston surface area compared to 2.5 Series shocks. This translates into increased stability and vehicle control at the extremes of off-road use, with benefits also making themselves apparent in on-road driving conditions. Increased internal oil volume and more external surface area compared to 2.5 Series Shocks offer improved heat dissipation and resistance to shock fade under hard use.
