These rear LCA features a fresh, machined design and is manufactured 
out of high-quality billet aluminum.  Being introduced first will be 
lower control arms with polyurethane bushings featuring six show-quality
 finishes, including raw-aluminum.  The next release will feature 
spherical bearings.  In addition, polyurethane bushings and spherical 
bearings will be available as replacements and upgrades.
 
 The unique feature of the new design allows bushings and bearings to be interchangeable on to the same arm.
