The R1 Concepts drilled and slotted brake rotor is listed for the rear left position on 1973–1998 International/Navistar S1854 conventional models. The description notes a black finish and a drilled-and-slotted braking surface for that application. Verify the S1854 model and rear left side when ordering to ensure the rotor aligns with the vehicle's rear brake mounting requirements.
