Mopar 68143491AB ABS Hydraulic Control Unit – Ram 2500/3500

Mopar 68143491AB is the genuine ABS hydraulic control unit (HCU) for late-model Ram HD trucks. It’s the heart of the anti-lock braking system, managing brake pressure to each wheel during hard stops and slippery conditions. Using a new OEM HCU helps restore proper ABS and stability control performance when the original unit fails or is contaminated.
