Whiteline motor mount inserts for 1973–1974 GMC C15/C1500 work alongside the original rubber mounts to reduce drivetrain rotation under hard acceleration and improve throttle response and shift feel. The inserts use a formulation that resists oil, grease and weathering and include internal grease reservoirs for continual lubrication. They are designed to complement the original bushing rather than replace it.
