Ours:
These are U.S. Alcoa 6061t6 billet aluminum, Lifetime warrantee, hub-centric and wheel-centric The spacers are roughly 3-5 times stronger than the Ford cast 20" wheels .
2" spacers will work without needing to cut off your existing wheel studs
We can get you 1.25-1.5" spacers but you will have to trim the studs shorter. But the back space with then be 4.5" and the rim will set like factory.
PM me if I can help.
