Sourcing parts for a full-size car comes down to matching the right generation, and that is where most orders go wrong. Epsilon II from 2010 to 2016 and a lighter redesign from 2017 to 2019.
The parts we ship most for the 2010 Buick LaCrosse are intake manifold gaskets, window regulators, headlamp assemblies, AC compressors and power steering components. These are genuine GM parts, engineered by the team that built the vehicle and held to the tolerances the original calibration assumed. On a full-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.
By 2010 the Buick LaCrosse was well into its production run, so most early build changes had been worked through. Livery and fleet versions of these sedans often carry different suspension and cooling parts from retail cars.
Run your VIN before ordering. It takes a few seconds and it is the difference between installing the part and shipping it back. We ship from Dallas, and in stock orders placed by 3pm Central usually go out the same business day. Cross-shopping a related truck? The 2010 Buick Enclave is the closest thing in the lineup that year.
