Does both sides take the same it just shows right side

Does both sides take the same it just shows right side


January 04, 2011
This caliper will not fit both sides. When this caliper is ordered, the customer will need to order an “L” (left or driver’s side) and an “R” (right or passenger’s side). This is what we call an "indexed” part number. The 910-31005 number gets us to the correct product, the “R” or “L” added at the end gets us to the “exact” application.
