into the frame rails.

INSTALL OR CONNECT
1. Straighten and deburr the rail ends as necessary to allow the service impact bar to fit properly.
2. Temporarily position the impact bar and scribe lines into the primer indicating where the welds will be made. Remove the primer from the areas to
be MIG welded by sanding with 80-grit paper on a 'Dual-Action' sander (DA). Do Not use a grinder to remove the primer.
3. Prepare all bare metal surfaces and apply weld-through primer as necessary. Be sure to apply primer to the inside of the 'fishmouth' area also.
NOTE: When installing the replacement bumper bar, weld the sides first in order to ensure uniform contact with the frame rails.
