Don't reuse your old rusty bolts when installing aftermarket A-arms when you can replace them with new ones. Our kit includes all new hardware for installing both upper and lower A-arms into the 1993-2002 GM F-body. This replacement hardware kit will work with the factory K-member and aftermarket K-members. All bolts supplied are 10.9 High grade bolts (equal in strength to American Grade 8), Nylon lock nuts and washers.
