A suspension travel control system (1046) for a vehicle suspension is disclosed. The suspension travel control system includes a stop post (834) secured to the vehicle frame and a suspension travel control formation that includes a base (1042) and a body (1048). The stop post (834) is positioned in a space defined by the body (1048). The suspension travel control formation may be secured to the axle, the main support member or incorporated into the axle coupling assembly to provide a rebound and jounce stop as well as longitudinal redundancy in the event of the failure or loss of a longitudinal linkage.

A front suspension lift kit for a golf cart includes first and second beams mountable to a frame of the golf cart. A first strut is mountable to the frame of the golf cart and a distal end portion of the first beam such that the first strut extends between the frame of the golf cart and the first beam. A second strut is mountable to the frame of the golf cart and a distal portion of the second beam such that the second strut extends between the frame of the golf cart and the second beam. A support bracket is mountable to the first and second beams at the distal end portions of the first and second beams. The lift kit also includes a swing arm, a spindle bracket, and a coil-over shock.

A sub-frame arranged to be mounted on a chassis of a car and to have the rear wheels of the car mounted thereon is arranged to receive an electric drivetrain arranged to drive the car. The sub-frame includes a cage including bars arranged to form an upper perimeter and a lower perimeter and a plurality of struts extending between the upper and lower perimeters; a pair of rear wheel suspension mounts, each rear wheel suspension mount being arranged to have one of the rear wheels of the car mounted thereon; and a plurality of brackets located on the cage and arranged to facilitate connection of the sub-frame to the chassis of the car and/or to the electric drivetrain. A frame and vehicle including such a sub-frame and a method of installing such a sub-frame are also disclosed.

A spring leaf for a leaf spring (1) has an upper side (13), a lower side (14), two lateral sections extending between the upper side (13) and the lower side (14), a longitudinal axis (15), a section plane (III) extending perpendicularly to the upper side (13) and lower side (14) and through the longitudinal axis (15), two end sections (3a, 3b), and a middle section (4) extending between the end sections (3a, 3b). The middle section (4) has a clamping region (5). A main tension region (6a, 6b) is provided between at least one of the end sections (3a, 3b) and the clamping region (5), the thickness (S) of which decreases in the direction from the clamping region (5) to the end section (3a, 3b), in particular decreases parabolically. The width (B) of the main tension region (6a, 6b) extending between the section plane (III) and a lateral section of the spring leaf (2) increases over a part of its length or over its entire length in the direction from the end section (3a, 3b) toward the clamping region (5) according to a quadratic function.
