About this part

Hydro-Booster for Freightliner · 2-TON (USPS - MT-45) / MT-45G / MT-55. 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.

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