Why Buy Dodge Ram Parts From All Dodge Truck Parts

We specialize in OEM Mopar parts for Dodge Ram trucks — Ram 1500, 2500, and 3500 — pulled from low-mileage donor trucks at our Rancho Cordova, CA yard. We stock new old stock and select aftermarket where it makes sense, but the bulk of our inventory is quality used OEM.

Every Part Is Inspected Before It's Listed

Mechanical components get checked for wear and damage. Electrical parts are inspected for corrosion, melted connectors, and prior repairs. Each listing includes the OEM part number and donor truck details so you know exactly what you're getting.

Confirm Fitment Before You Order

Dodge made running changes within model years, and sub-models like Cummins diesels and Hemi V8s can complicate fitment. The fastest way to verify the right part is to match the OEM part number stamped on your original. No part number? Call us at (916) 635-7602 with your VIN and we'll confirm before you order.

Shipping and Returns

We ship nationwide from Rancho Cordova, CA, with most orders going out within 1–2 business days. Unopened parts can be returned within our standard return window. Parts that have been installed or modified are non-returnable, which is why we recommend confirming fitment first.

Common Questions

  • Are used OEM parts reliable? Pulled from good donor trucks and properly inspected, yes. Used OEM gives you exact factory fit and original connectors — usually a better outcome than aftermarket on complex parts.
  • Don't see what you need? We have inventory not yet listed online. Call (916) 635-7602 or use VIN search.
  • Need help figuring out what part you need? We work on these trucks every day. Tell us your symptoms and your truck's year/model and we'll point you in the right direction.
