DFC GEOSPEC Coated Rotor Details

The DFC GEOSPEC Coated Rotor line is focused on corrosion protection and OE-style fitment for brake service. This rotor is specified as a vented front rotor with dimensions that match the listed Ford truck applications, including 1980-1994 Ford F-250 and Ford F-350 front brake setups. The 604-54108 rotor is a direct replacement choice for trucks that require the listed rotor-only configurations, including heavy-duty and standard-duty variants with the noted drum hub or rear shoe combinations.

Compatible With Ford F-250 and Ford F-350 front brake service, this rotor is listed for applications such as 1990-1994 Ford F-250 front with 12 x 3" rear shoes or 12 x 2-1/2" rear shoes, and 1987-1994 Ford F-350 front with dual rear wheels. It also covers earlier Ford F-250 and Ford F-350 front rotor-only configurations across the 1980-1989 model years.

Common Problems This Rotor Can Address

• Brake pulsation caused by rotor wear or thickness variation
• Reduced braking consistency from heat buildup in front brake service
