3. Remove the original shock and inspect the mounting brackets, fasteners, bushings, brake hoses, and travel limits.
4. Cycle the suspension carefully to verify that the FTS77191 travel will not bind or become the limiting strap.

6. Repeat on the opposite side with the matching separately purchased shock, then verify clearances and road-test the vehicle.
