Abstract: A skateboard truck assembly (10) having a main body (11) for mounting to the underside of a skateboard deck, an axle (24) carrying skateboard wheels (25) and mounted intermediate its opposite ends to the main body (11) via a rotatable steering adjustment body (20) for pivotal movement in a steering plane, the steering adjustment body (20) being mounted to the main body (11) for rotation about an axis extending transversely of the body (11) such that a change in the rotational position of the steering adjustment body (20) adjusts the pivot axis of the axle (24) and thus the steering characteristics of the truck assembly (10)

Abstract: A truck assembly for a skateboard, having a body for mounting to the underside of a skateboard deck. The body supports an axle and wheels mounted for pivoted movement for steering and includes adjustment means for varying steering characteristics of the skateboard. The axle may be mounted by a pair of opposite trunnions which define a pivot axis for the axle. The pivot axis is adjustable by a rotatable boss, preferably with a pivot arm which may be locked in place by a spring loaded pin inserted into a selected aperture. The truck may include two pairs of angled springs which are arranged similar to adjacent sides of a triangle and adapted to centre the axle. The truck assembly may include a removable spacer locatable between the deck and axle and extension pieces for the axle.
