Steeda Hardcore S550 Differential Bolts
Steeda THRU Threaded hardware reinforces the Super 8.8 differential’s rear attachment to the IRS subframe. Custom bolts thread through the assembly without drilling bushings or the differential housing.
Heat-treated 4130 chrome-moly steel is claimed to provide strength comparable to class 12.9 fasteners, addressing factory-bolt failures under heavy use.
Intended for use with Steeda Hardcore differential brackets 555-4050.
