Installation Notes and Tips

Verify crankshaft journal size, housing bore, and oil clearance before assembly. Clean all mating surfaces thoroughly, lubricate the bearing surfaces during installation, and confirm that the bearing shells seat fully in the rod and cap. Because fitment varies by engine family and year, match the vehicle application and engine specification before ordering. Compatible vehicle examples include Fits 1969-1973 Ford Mustang, N/A; Fits 1977-1996 Ford F-150, N/A; and Fits 1983-1989 Mercury Grand Marquis, N/A.
