Heavy trucks need heavy suspension, Terrafirma has developed the Big Bore Expedition shock specifically for fully laden Land Rovers such as overland and utility vehicles. The Big Bore Expedition shocks are designed to handle the battering experienced when travelling over rough terrain while providing stability and control with top heavy vehicles at both low and high speed. The Big Bore Expedition shock is built for strength and reliability, it is true when they say that 'size does matter!' Everything about The Big Bore Expedition shock is massive with its 76mm diameter body, 50mm piston and of course Terrafirma�s super strong 20mm double chromed shaft. The fully welded mounting points and the natural rubber bushes are the largest possible to fit Land Rover's original mounting points. The massive 76mm shock body provides ample capacity for the high performance oil necessary to keep the internal workings cool while maintaining high damping performance even when combined with the high spring rates required to carry very heavy loads. Coincidentally fitting the Big Bore expedition shocks to a light or un-laden Land Rover gives a firm, sporty handling characteristic often sought after by the more performance orientated driver.
