Abstract
A suspension is provided for coupling a front wheel with a chassis of an off-road vehicle. The suspension comprises upper and lower suspension arms that each includes two inboard mounting points to the chassis and one outboard rod-end joint to a spindle assembly coupled with the front wheel. A ball comprising each outboard rod-end joint is fastened by way a bolt between a pair of parallel prongs extending from the spindle assembly. The upper suspension arm is configured to facilitate coupling a strut between the lower suspension arm and the chassis. A steering rod is coupled with the spindle assembly by way of a steering rod-end joint that is disposed forward of a drive axle, thereby decreasing leverage of the front wheel on the steering rod and substantially eliminating bump steer that may occur due to rough terrain.

A suspension for coupling a front wheel with a chassis of an off-road vehicle, comprising:
- a spindle assembly coupled with a front wheel comprising:
- a first set of parallel prongs disposed at a of the spindle assembly;
- a second set of parallel prongs disposed at a bottom of the spindle assembly;
- a third set of parallel prongs disposed at a front of the spindle assembly;
- and
- a hole disposed between the first and second sets of parallel prongs configured to couple with a constant velocity (cv) joint;
- an upper suspension arm comprising two inboard mounting points coupled to the chassis and one outboard rod-end joint coupled to the spindle assembly via the first set of parallel prongs;
- a lower suspension arm comprising two inboard mounting points coupled to the chassis and one outboard rod-end joint coupled to the spindle assembly via the second set of parallel prongs;
- a strut comprising a shock absorber and a coil spring that are coupled between the lower suspension arm and the chassis;
- and
- a steering rod that is coupled with the spindle assembly via the third set of parallel prongs by way of a steering rod-end joint.

- a second set of parallel prongs disposed at a bottom of the spindle assembly;
- a third set of parallel prongs disposed at a front of the spindle assembly;
- and
- a hole disposed between the first and second sets of parallel prongs configured to couple with a constant velocity (cv) joint;
- an upper suspension arm coupled to the spindle assembly via the first set of parallel prongs by an outboard rod-end joint and coupled to the chassis by at least one or more inboard mounting points;
- a lower suspension arm coupled to the spindle assembly via the second set of parallel prongs by an outboard rod-end joint and coupled to the chassis by at least one or more inboard mounting points;
- a strut coupled between the lower suspension arm and the chassis;
- and
- a steering rod coupled to the spindle assembly via the third set of parallel prongs by a steering rod-end joint.
