1955-1957 Chevrolet Passenger Car Tubular Control Arms CA003-4

Suspension geometry is improved over stock by adding 5 degrees positive caster, and improving roll camber. The control arms feature stainless steel cross shafts which incorporate aluminum bushings. You can adjust caster by moving the upper control arm fore/aft for more or less caster without adding alignment shims. The upper control arms also have greaseable bushings which make for better stiffness to provide more consistent handling. 

The  lower control arms replace stock lower control arms.  These new tubular lower control arms feature a tubular design with gussets and cross braces, bushings with steel housings and crush tubes, and a powder coated gloss black finish. The geometry features include additional positive caster.
