Auto parts and heavy-duty tires you can trust, shipped from Battle Creek, Michigan
Mason’s Auto Store is the online counter of Mason’s Auto Parts, a family parts business serving car and truck owners since 1936, now shipping from our US address at 57 4th St, Battle Creek, Michigan. Online, we sell the same thing we always have: the right part at a fair price, chosen with the help of people who work on vehicles every day. Our catalog covers new genuine OEM parts, remanufactured assemblies and tested used parts for the vehicles Americans drive most — the Toyota Camry, Honda Civic, Ford F-150, Chevrolet Silverado, Subaru Outback, Jeep Wrangler and Porsche Cayenne, Macan and 911 — plus Nissan, Hyundai, Kia, Ram, GMC, Lexus, Mazda, Volkswagen and BMW.
Complete engines from $2,000
Our engines department lists complete engines for Class 8 trucks — Cummins ISX15 / X15 14.9L (Kenworth T800, W900), PACCAR MX-13 and Caterpillar C15 ACERT — Ram 5.7 HEMI, 3.0 EcoDiesel and 6.7 Cummins, Toyota Hilux 1GD-FTV and 1KD-FTV, Land Cruiser 3UR-FE, 1VD-FTV and 1GR-FE, Corolla, Camry, Civic, CR-V, Elantra, Forte, Sorento, Mazda, F-150, Silverado, Wrangler, Outback and Cayenne engines. Every engine is matched to your VIN or engine data plate before it ships by freight.
Heavy-duty truck, OTR and SUV tires
Fleets, contractors, farms and 4×4 owners can now buy new tires from Michelin, Bridgestone, Continental, Yokohama, Double Coin, Kumho, Triangle and Alliance: truck and bus tires for steer, drive and trailer axles (11R22.5, 11R24.5, 295/75R22.5, 315/80R22.5, 385/65R22.5), OTR and earthmover tires for loaders, articulated dump trucks, graders and mobile cranes, forestry flotation tires and SUV and light-truck tires from about $200 per tire. Large tires ship by freight anywhere in the USA.
Engine parts matched to your engine
Our engine parts name the exact engine they fit — 3.5L and 2.7L EcoBoost, 5.0L Coyote, 4.3L EcoTec3, 3.0L Duramax, 1.5L turbo and 2.0L Honda, 2.5L Toyota and Subaru boxer, 3.6L Pentastar and 3.0L EcoDiesel — so you order the right water pump, turbocharger, timing chain, injector or mount the first time.
Shop by year, make and model
Every product carries its fitment: the model years, the make and model, and notes such as engine size, drive type, trim or side. Choose your vehicle in the Shop by Vehicle bar and the store hides everything that does not fit. We remember your vehicle while you browse, so you can move from brakes to filters to lighting without choosing it again. Still unsure? Add your VIN at checkout and we verify fitment for free before we ship.
Every condition, every part tested
Not every repair needs a brand-new part. We source from four places and label each listing clearly: new OEM parts from factory supply, remanufactured units rebuilt to specification, refurbished parts recovered from accident vehicles, and used parts from licensed salvage yards. Whatever the source, each part is inspected and tested before it is sold, and the warranty is stated on the product page.
Pay the way you prefer
Checkout accepts major credit and debit cards, Apple Pay and Google Pay, Afterpay (pay in four), Zelle, Cash App and bank transfer. To protect you and us, orders ship once the payment is confirmed, and optional shipping insurance is offered at checkout through our partner.
Bulk orders for shops and fleets
Repair shops, body shops, dealers and fleet managers can send one bulk inquiry with a list of parts and vehicles and receive a single quote with volume pricing — usually within one business day.
