Genuine GM Parts for the 2011 Buick Regal
Select The Trim & Engine Of Your Vehicle Below
Getting parts right on a mid-size car starts with knowing which generation you are working on. Epsilon II from 2011 to 2017 and the E2XX Sportback and TourX from 2018 to 2020.
2011 is a carryover year for this vehicle. That makes sourcing simpler in the mechanical systems and no simpler at all in trim and body. Engine option is the main catalog split on these sedans, and it runs through the cooling system, exhaust and accessory drive.
The parts we ship most for the 2011 Buick Regal are timing chains and guides, window regulators, headlamp assemblies, AC compressors and front wheel bearings. Everything on this page is a factory GM part, built to the original specification and carrying the original part number. On a mid-size car these are the components that carry load and heat, and they are where an aftermarket substitute costs you the job twice.
One thing worth knowing about buying OEM: the part number ties back to GM's own engineering records, so when a component is revised the supersession is documented rather than guessed at. Aftermarket catalogs have no equivalent, which is why a listing that says it fits a range of years is often wrong at the edges.
If you are not certain which version you have, give us the VIN and we will confirm fitment before you check out. In stock orders placed by 3pm Central typically leave our Dallas warehouse the same day, so most of the country sees short transit times. Cross-shopping a related truck? The 2011 Buick Enclave is the closest thing in the lineup that year.
