A system to stabilize a construction vehicle having a frame and a pair of stabilizing legs with ground-engaging shoes at the ends of the legs. The stabilizing legs pivotally connect to the frame on substantially opposing sides, so that the stabilizing legs pivot upwards to a stowed position and pivot downwards to a stabilizing position where the shoe engages the ground. Further, the stabilizing legs telescope between a retracted position and an extended position. The retracted position locates the shoe closer to the vehicle and the extended position locates the shoe further from the vehicle. A pair of hydraulic cylinders connect to the respective stabilizing legs to power the telescopic movement of the stabilizing legs between the retracted position and extended position.
