Some Ridetech tubular control arms feature removeable slugs in the cross shafts. The slugs included W/ the arms (along w/ the design of the control arm) will generally allow as much as 7 degree's positive caster.

Offset slugs will shift the arm fore/aft to give more caster adjustment, which may be needing in racing applications or W/ a chassis outside of factory tolerances.

Note: These are sold individually. For a pair of arms you will need to select a quantity of 4.
