AutoBuffy Officially Launches ACDelco® Products
AutoBuffy is now licensed by General Motors to display the full ACDelco® catalog — the same parts brand that comes pre-installed in every new Chevrolet, Buick, GMC, and Cadillac. OE specs, OE warranty, dealer-grade fitment, direct online prices.
Today, AutoBuffy is officially licensed by General Motors to display the ACDelco® parts catalog online, direct from GM. The full catalog goes live on autobuffy.com in June 2026.
No third-party catalog here. No scraped data. This is the same product information GM uses internally, and soon it'll power ACDelco lookups on autobuffy.com.
First — Let's Clear Something Up
Say "ACDelco" and most people picture *aftermarket replacement parts*.
That's only half the story.
ACDelco is GM's complete service parts brand. Both the parts that came pre-installed in your vehicle at the factory, and the OE-quality replacement parts GM dealers install during warranty service. Take a 2024 Silverado to a Chevrolet dealer for an oil change and the filter going in is ACDelco. A GMC tech replaces a sensor on a Sierra under warranty? That sensor is ACDelco. When a Cadillac CT5 rolls off the assembly line in Lansing, the spark plugs, battery, brakes, and dozens of other components are ACDelco.
It is the GM brand. Not "like" the GM brand. The GM brand.
A Brand That Predates Most Car Companies
Here's a fact most people don't know.
The "AC" in ACDelco comes from Albert Champion, who founded the AC Spark Plug Company with Buick Motor Company in 1908. The "Delco" comes from Dayton Engineering Laboratories Co., founded by Charles Kettering and Edward Deeds in 1909. Kettering was the man who invented the electric self-starter.
Two companies. Both older than Ford's Model T as a mass-market success. Both eventually folded into General Motors, then merged into the brand we know today.
Call it over 115 years of continuous heritage building parts for American cars and trucks.
The ACDelco Tiers Most People Don't Know About
ACDelco isn't a single product line. It's three.
- ACDelco GM Original Equipment. The parts pre-installed at the factory on new GM vehicles. The literal source.
- ACDelco Gold (Professional). OE-spec replacement parts, manufactured to the same engineering standards as the OE part. What dealerships install for warranty work and what techs trust for repair jobs.
- ACDelco Silver (Advantage). Quality-tier replacement parts engineered for value, with coverage for older GM vehicles and broader applications.
What makes that ladder unusual: most replacement brands start in the aftermarket and work their way *toward* OE specs. ACDelco moves the other direction. It starts at the GM assembly line, and the same engineering DNA carries down through the Gold and Silver replacement tiers. That's a real difference, and it shows up where it counts: the fit, the materials, the warranty behind the box.
Plus GM Genuine Parts
ACDelco isn't GM's only OE service brand. A lot of the parts launching on AutoBuffy wear the GM Genuine Parts label instead, GM's other OE line, used heavily across collision and powertrain replacement. Different label, same source: GM.
Search a GM application on AutoBuffy and you may see both ACDelco and GM Genuine Parts come back. Both are GM. Both are OE. We surface them exactly as GM catalogs them.
Manufactured by the Same Companies that Supply GM's Factories
This is the part that surprises people most.
ACDelco doesn't run one giant factory making everything in-house. It contracts with the same Tier-1 suppliers GM uses for original equipment, companies like Bosch, Denso, Continental, Mahle, and Delphi. The brake pad on your factory-fresh Tahoe might come off the same production line as the ACDelco Gold brake pad in the box you buy to replace it.
That's why the fit is identical. Because the part is identical.
What's Launching on AutoBuffy
The full ACDelco catalog, across 30+ product lines, covering:
- Brakes: pads, rotors, calipers, drums, hoses, hardware
- Ignition: spark plugs, coils, wires, distributor components
- Suspension & Steering: shocks, struts, control arms, ball joints, tie rods, pumps

When ACDelco goes live on AutoBuffy, the fitment data, product specs, packaging dimensions, images, and warranty info all come straight from GM's source catalog. Nothing stitched together from third-party feeds.
The Story Behind the Brand
From the Founder
"Adding ACDelco brings real value to our customers. It gives them the option to put on their car the same brand GM installed at the factory, a brand with over a century of proven performance on the road, backed by the engineering and warranty that GM stands behind.
That's our goal at AutoBuffy: bring people the brands they've already trusted on their cars for decades. Brands that have earned their reputation through real success, real durability, and real time on the road. Not generic replacements. Not private-label gambles. The brands that have proven themselves by lasting.
General Motors has been a great team to work with, and we're just getting started."
— Chetan Chadha, Founder & CEO, AutoBuffy
What This Means for You
Trust. The fitment, specs, images, and warranty information come from GM's source. Not assembled from scraped data or best-guess crosswalks.
Accuracy. No more "fits 2014–2018" when GM's data says 2015–2017. We use source data, so what we show you is what GM says.
Coverage. From a 1998 K1500 to a 2024 Silverado EV, from a CTS-V to a Trax. If it's GM-built, the catalog supports it.
Honest pricing. Dealer-grade parts at non-dealer prices, shipped fast, with real fitment confidence behind every order.
For shops. Wholesale-friendly catalog access, a fitment engine designed for the way a tech actually works, and direct access to OE-grade brands like ACDelco at honest prices. Run a shop and want early access to wholesale terms? Reach out. We want to build this with the people doing the work.
Built on Our Own Technology
AutoBuffy pairs OE brands like ACDelco with our own AI fitment engine, built in-house. That's how we can ingest a catalog this size in under a week instead of years, and why the fitment you see beats third-party feeds for accuracy. The catalog is the product. The technology is what makes it usable.
Launching June 2026
The full ACDelco catalog goes live on autobuffy.com in June 2026. When it does, you'll plug in your vehicle, search for the part you need, and the catalog you see will be the GM catalog, surfaced the way it was meant to be presented.
Drive a GM-built vehicle? This one's for you. Run a shop that works on GM vehicles every day? This one is *definitely* for you.
