If you run a repair shop, every dollar spent on parts comes out of your margin. If you're fixing your own car, dealer prices can make a repair not worth doing. We solve both problems with genuine OEM Buick parts at wholesale prices.

Every part we sell comes from a genuine Buick donor vehicle, so you get real GM factory parts, not copies. Hunting for a used Buick transmission for sale for a discontinued model? We can usually track one down.

Inspected engines
Direct-fit OEM engines, including the 1.4L turbo from the Encore, the 2.0L turbo from the Envision and the 3.6L V6 from the Enclave and LaCrosse. A 2015 Buick Encore engine for sale is one of our most requested. Every engine is compression tested and checked for sludge and oil consumption before shipping.
Tested automatic transmissions
6-speed and 9-speed automatics (including the 9T65) for late-model and classic Buicks. We check fluid conditions and shift solenoids so each unit shifts cleanly.
Remanufactured and rebuilt options
Planning to keep your Buick for years? Ask us about a Buick remanufactured engine or a rebuilt Buick transmission for sale. They cost more than used, but often come with longer warranties.

Live VIN Match
Skip the Guesswork. Let a Specialist Match Your Buick VIN.
Ordering the wrong engine block or transmission code costs you days. Our US-based parts specialists check your VIN live on the phone and confirm the OEM match before you pay.
Skip the dealer wait times and markups. We ship hard-to-find OEM Buick parts to your driveway or your shop, from heavy-duty transfer cases and axles to instrument clusters, climate controls and airbags.
Give us your 17-character VIN. We match it to the part's OEM number and the donor car's engine or transmission code, and a specialist confirms the fit before shipping.
Yes. Every part comes with a 90-day warranty. Extended coverage is available on engines and transmissions.
Usually, yes. Our nationwide salvage network covers models no longer sold new, from the LeSabre and Park Avenue to the Rendezvous and Terraza.
Yes. Engines and transmissions can be shipped directly to your shop via priority commercial delivery. Liftgate delivery available on request.
For most repairs, yes. Used OEM parts were built by GM for your exact vehicle, so they fit and perform like the originals. Aftermarket parts are new, but fit and quality can vary.
Engines get a compression test and are checked for sludge and oil consumption. Transmissions are checked for fluid condition and shifting where possible.
The 3.6L V6 in 2008–2012 Enclaves often suffers timing chain stretch, especially with long oil change intervals. A tested 2010 Buick Enclave engine for sale is often cheaper than replacing all the chains.
Yes, if it's tested. Early Enclave 6-speed automatics are known for wave plate failure. Ask us whether the unit has the updated wave plate before you buy.
The 2.4L engine is widely reported for oil consumption caused by piston ring problems. If yours is too far gone, a 2011 Buick LaCrosse engine for sale is a common fix.
A used engine costs less and suits most budgets. A Buick remanufactured engine, like a rebuilt Buick transmission, costs more but usually has a longer warranty. Go remanufactured if you're keeping the car for many years.
You don't need a local junkyard. Searching for used Buick parts near me usually turns up yards with limited stock and no warranty. We ship tested OEM Buick parts to your home or shop anywhere in the US, with a 90-day warranty and VIN-matched fit.
Ready when you are
Your Buick.Your VIN. Verified.
Wrong parts mean returns and lost days. Send us your VIN and we'll confirm the exact OEM fitment before you buy. That covers everything from a used 2014 Buick Encore transmission to an engine for your Enclave or LaCrosse.
