About this part
Vacuum Booster for Buick / Chevrolet / GMC +2 makes. 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.
