About this part

Hydro-Booster for Medium-duty truck · Ford / Navistar / Chevrolet-GMC / Mack. A hydraulic booster (hydro-boost) uses power-steering pressure instead of vacuum to assist braking — common on diesel and heavy-duty trucks where engine vacuum is limited. Brand-new unit — not a remanufactured core. OE and Cardone numbers are used only as a cross-reference, so you can order by a number you already know. Shown in real product photos.

VACTIRO confirms fitment by VIN or OE before any quote is issued. No payment is requested until availability, price and return terms are confirmed.
