The Wheel-Guard Separator Plate is approximately .040" thick. It is
placed between the hub or drum and the wheel, and/or between two wheels
in dual applications. Not to be installed between hub and brake drum.
The Wheel-Guard is recommended in severe applications where corrosion
and/or wear have been identified. Both aluminum and steel wheels can
benefit from use of the Wheel-Guard. Care must be exercised in centering
the separator plate prior to torquing, and stud length must be checked
as each plate is approximately .040" thick.
