Claim 13:
14. The steering system of claim 12, wherein the rack and pinion gearset is a ram assist rack and pinion gearset;
wherein secured to a firewall is the augmented chain and sprocket assembly, the assembly is vertically oriented such that the first rounded end is at the top while the second rounded end is at the bottom, the input shaft of the augmented chain and sprocket assembly is directed backward towards the steering wheel and is pivotally connected to an end of a steering column that is opposite of the steering wheel, while the output shaft of the augmented chain and sprocket assembly is directed forward towards the front axle and is pivotally connected to the back end of the coupler shaft, the front end of the coupler shaft is pivotally connected to an input shaft of a control valve while an output shaft of the control valve is pivotally connected to the back end of the steering shaft, and the front end of the steering shaft is pivotally connected to a pinion shaft of the ram assist rack and pinion gearset;
wherein cooperation among the augmented chain and sprocket assembly, coupler shaft, control valve, and steering shaft enables steering input to be transmitted from the steering column to the ram assist rack and pinion gearset;
wherein the ram assist rack and pinion gearset is attached to the front axle between a differential housing and a driver side inner-C end forging;
wherein a first end and a second end of a ram of the ram assist rack and pinion gearset are connected to a driver-side end and a passenger-side end of a rack of the ram assist rack and pinion gearset, and to a first end and a second end of a tie rod bar of the ram assist rack and pinion gearset, the mid-point of the tie rod bar is pivotally connected to the first end of the draglink while the second end of the draglink is pivotally connected to the passenger-side steering knuckle, the passenger-side steering knuckle is pivotally connected to the first end of the tie rod while the second end of the tie rod is pivotally connected to the driver-side steering knuckle;

wherein cooperation among the ram assist rack and pinion gearset, draglink, and tie rod enables steering input to be transmitted from the ram assist rack and pinion gearset to the driver-side and passenger-side steering knuckles, transmission of steering input to the driver-side and passenger-side steering knuckles enables the driver-side and passenger-side steering knuckles to turn, and thereby turn the vehicle.
