Abstract: An overload suspension system configured for operative engagement to a vehicle having a first leaf spring and second leaf spring to provide auxiliary support to the vehicle when overloaded. A first control arm attached to a first torsion bar has a distal end positioned a separation distance from the first leaf spring. A second control arm attached to the second control arm has a distal end positioned substantially the same separation distance from the second leaf spring. The suspension system operates as an auxiliary suspension only when added weight to the vehicle deflects both leaf springs to contact a respective one of the control arms, thereby preserving the ride and suspension characteristics of the vehicle when the added weight is not present.

Abstract: A vehicle shock absorber has a body extending between a first end and a second end. Translation of a primary shaft within an interior cavity of the body communicates a first volume of fluid within the interior cavity to a secondary reservoir where it increases pressure in a gas cavity therein. The primary shaft has an annular member engaged thereon which contacts a bump shaft slidably located in an opening at the first end of the body. The contact of the annular member translates the bump shaft within the interior cavity to cause communication of a secondary volume of the fluid to the secondary reservoir.
