Fitment verified for the Horton 79A9798RMAN reman fan clutch. The dealer 'FAN HUB' label is a misnomer; this is a fan clutch, not a hub. Specific truck models are not detailed, but the part is used on multiple Peterbilt and Kenworth models with the ISX engine.

It uses eddy current for a lower fan speed during light cooling demand and spring-actuated full engagement when maximum airflow is needed, improving fuel economy and reducing noise. The clutch is replaced when the original unit fails—common signs include a locked-up fan (constant roar), no engagement (overheating), oil leaks, or excessive bearing play. It is a direct drop-in replacement for the same Horton model on Cummins ISX engines in Peterbilt and Kenworth trucks.
