About this part

Vacuum Booster for Ford · F-250 / F-350. A vacuum booster multiplies pedal force using engine vacuum for lighter, more consistent braking — a failing one usually shows up as a hard pedal and longer stops. 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.
