- (a) an upper truck secured to an end portion of said frame having a horizontal upper portion with opposing lateral ends, each lateral end having a spring retention means thereon, and a vertical lower portion extending downward from said upper portion having a front and back walls so as to define a channel in the upper truck and an opening in said front and back walls for a pivot pin;
- (b) a lower truck having a vertical upper portion with front and back walls so as to define a channel in the lower truck and an opening through said front and back walls for a pivot pin, said vertical upper portion extending inward to a lower horizontal portion with opposing lateral ends, each lateral end having a spring retention means thereon;
- (c) a pivot pin extending through the openings in the walls of the upper and lower trucks to secure the upper and lower trucks together; and
- (d) one or more vertically positioned coiled springs having two opposite ends, one end in engagement with the spring retention means on the upper truck, and the other end in engagement with the spring retention means on the lower truck, and
- (e) wherein the shock absorber is placed within the interior of the spring coil between the spring retention means.
- 2. A truck assembly as in claim 1 wherein the shock absorber is a cylinder.
- 3. A truck assembly as in claim 1 wherein the shock absorber is rectangular.
- 4. A truck assembly as in claim 1 wherein the shock absorber comprises at least one upper or lower curved surface.

- (e) an upper truck secured to at least one end portion of said frame having a horizontal upper portion with opposing lateral ends, each lateral end having a spring retention means thereon, and a vertical lower portion extending downward from said upper portion having front and back walls so as to define a channel in the upper truck and an opening in said front and back walls for a pivotal pin;
- (f) a lower truck having a vertical upper portion with front and back walls so as to define a channel in the lower truck and an opening through said front and back walls for a pivot pin, said upper portion extending downward to a lower horizontal portion with opposing lateral ends, each lateral end having a spring retention means thereon;
- (g) a pivot pin extending through the openings in the walls of the upper and lower trucks to secure them together;
- (h) one or more vertically positioned coiled springs having two opposite ends, one end in engaging with the spring retention means on the upper truck and the other end in engagement with the spring retention means on the lower truck;
- (i) an axle having opposite ends, said axle being secured to the upper or lower truck; and
- (j) wheels rotatably mounted on the opposite end of the axle, whereby when the rider of the board tips one side of the deck downwards the upper and lower trucks rotate relative to each other about the pivot pin enabling the sport board to turn in the direction of the downward side of the board, and
- (k) further comprising the shock absorber situated within the interior of the spring coil.
