A slider for adjustment of the suspension of a vehicle longitudinally with respect to the body of the vehicle, the slider comprising a pair of side rails, a frame adapted to carry the suspension slidable longitudinally of the body on the side rails, and a plurality of locking pins for locking the frame in various positions of adjustment relative to the side rails. The slider further comprises apparatus for retracting said locking pins including linkage interconnecting said pins for conjoint movement of the pins between extended and retracted positions. The linkage includes a shaft extending longitudinally of the frame, a crank for rotating the shaft, and a plurality of links interconnecting the shaft and the locking pins so that rotating the shaft retracts and extend the pins. A pull rod connected to the crank is manually movable from a first position to a second position for rotating the crank to rotate the shaft. A spring is connected at one end to the shaft and at the other end to the crank so that if one or more of the locking pins is stuck in extended position the spring deflects to permit the pull rod to move from its first position to its second position and turn the crank while the spring urges the shaft to rotate to retract the locking pins. The pull rod can be secured in its second position so that the spring continues to urge the shaft to rotate to retract the pins.
