We are a family-owned business helping drivers, technicians, and shops find the right used engine or transmission — without the run-around.
State Side Auto Parts is a family-owned supplier of used engines and transmissions. We serve everyday drivers, fleet operators, independent mechanics, and repair shops across the United States.
What started as a small operation has grown into a trusted source for hard-to-find drivetrain parts — but the way we work has not changed. We pick up the phone. We answer questions. We treat every customer like a neighbor.
If you are unsure about fitment, mileage, or what to ask for, talk to us. We will help you figure it out before you commit to anything.
We confirm year, make, model, and engine or transmission codes before quoting anything — and we verify VIN compatibility wherever possible.
Parts are reviewed for visible condition, fluid integrity, and basic mechanical signals before they leave the supplier facility.
You will hear from a real person who can explain mileage, sourcing, shipping times, and what to expect — in plain English.
Send a short message and we will get back to you with availability and pricing.

Real feedback from real customers who got the parts they needed at fair prices.
"Needed a 6.4L Powerstroke for my 2008 F-250. These folks found one, ran me about 60% of what the dealer wanted for a rebuild. Sales guy was upfront about the mileage and the 5-year warranty. Engine's been in the truck for two years, no complaints."
"My husband's 2012 Tahoe needed a new transmission. Wasn't sure where to start. They walked me through it, found one with low miles, shipped it to our shop. Honest pricing, did what they said they'd do."
"Don't normally do reviews but these guys earned it. 5.3L Vortec for my 2010 Silverado, shipped to my driveway in 5 business days. Mechanic said it looked like it had been pulled clean. Fair deal."
"Was nervous about ordering a used transmission online for my 2009 LaCrosse but my regular mechanic recommended them. Unit arrived when promised, paperwork all included. Saved me about $1,400 vs buying new. Only knock is shipping took a day longer than estimated."
"Bought a used 5.7L Hemi for my 2011 Ram 1500. Took a couple days for them to find the right match but they kept me updated. Came with the warranty paperwork my shop needed. Solid experience."
