SB - Small Ball studs are also high misalignment and in addition are made with the smaller 1-7/16” ball used on upper ball joint. This allows a smaller housing for added rotor clearance.
HIGH MISALIGN
HM - High Misalignment Studs have been tapered down at the neck for additional misalignment. Allows 2.40° more misalignment than our standard stud. The extra misalignment allows for approximately .55" of additional suspension travel.
