About Us

Who We Are

Trinity Auto Parts LLC is a Sacramento, California supplier of inspected used OEM and remanufactured auto parts, founded in 1990. We sell to independent repair shops, dealers and do-it-yourself owners across the United States and Canada. Every part we sell comes from a well-maintained running vehicle and is fully tested, inspected and guaranteed before it ships, which is how we can supply an engine, transmission, ABS module or steering column for a specific year, make and model with confidence.

How We Source and Inspect Parts

Every used part we sell is pulled from a donor vehicle with documented mileage and inspected before it is offered to you. What that inspection involves depends on the part: engines are checked for compression, oil pressure and external leaks; transmissions for shifting and leaks; ABS units for pressure retention and sensor response; hub and knuckle assemblies for runout and cracks; control modules for correct operation. Remanufactured units come from rebuilders who replace wear components and test the finished part. Before anything ships we match it to your VIN, so the part you receive is the one your vehicle actually takes.

What You Can Expect

• ✓Free shipping to commercial addresses in the continental United States, with shipping to Canada and residential addresses quoted up front.
• ✓Typical delivery in 3–5 business days. Large freight items such as engines, transmissions and complete axle assemblies can take 7–10 business days.
• ✓A warranty on every part, up to 2 years on select parts. The exact term is stated on your quote before you pay.
• ✓Free return shipping if a part is wrong or defective — see our return policy for the details.
• ✓Tested, A-grade parts only. If a part fails inspection, it does not get sold.

How Buying From Us Works

1. Tell us what you need. Use the quote form on any parts page, call +1 725-208-4566, or email [email protected]. Your VIN, year, make, model and the part you need are enough to start.

2. Get a written quote. We confirm fitment against your VIN and send a quote that states the price, the warranty term and the delivery estimate. There is no obligation.

3. Approve and receive. Once you approve, the part is pulled, packed and shipped with tracking. Our team stays reachable after delivery if your installer has questions.

Accredited and Accountable

Trinity Auto Parts is accredited by the Better Business Bureau. We do not collect reviews on this website; customers leave their reviews directly on our BBB profile, where they are verified independently of us. If you have bought from us, that is the place we would ask you to share your experience.

Our Promise

Honest advice on whether a used or remanufactured part is the right choice for your vehicle, a transparent quote with nothing added later, and support after the sale. If we cannot find the right part for your vehicle, we will tell you rather than sell you the wrong one.
