Front Suspension

LOWER CONTROL ARM
The lower control arm is a ductile iron casting using 2 rubber bushings to isolate it from the front suspension crossmember and body of the vehicle. The isolator bushings consist of 2 metal encased rubber isolated pivot bushings. The front of the lower control arm is bolted to the front crossmember using a bolt through the center of the rubber pivot bushing. The rear of the lower control arm is mounted to the front suspension crossmember using a thru-bolt. The lower control arms are inter-connected through a linked rubber isolated sway bar.

UPPER CONTROL ARM
The upper control arm is a high strength steel stamping. The upper control arm uses the 2 rubber bushings of the upper control arm/shock absorber mounting bracket to isolate it from the mounting bracket and the body of the vehicle. The isolator bushings used in the upper control arm are a metal encased rubber isolated pivot bushing. The bushings isolate the upper control arm from the body of the vehicle yet allows for the up and down movement of the control arm during the jounce and rebound travel of the vehicle suspension. The upper control arm is bolted to the top of the steering knuckle using the upper ball joint.
