Frequently Asked Questions
What is the warranty?
Up to 3 years, depending on the specific unit. The exact warranty term is listed on each product page.
What does ASE-tested mean?
ASE-certified technicians compression-test every cylinder and run leak-down evaluation on engines. Transmissions are Shift-Tested through all gears under load. Plus noise & smoke verification, visual inspection, and multi-angle photography before shipment.
How long until delivery?
Prep and ship time is 3-5 business days. Transit time is 2-3 business days after dispatch via freight carrier. Total: typically 5-8 business days from order to delivery.
Can I see photos before I buy?
Yes. Multi-angle photos of the actual unit sent before payment. If you do not approve the photos, you get every dollar back — no questions, no restocking fees, no return freight charges.
Do I need my VIN?
Strongly recommended for exact-fit matching. Engines and transmissions vary significantly by trim, body style, drivetrain (FWD/AWD/RWD), and year. Text your VIN to
+1-307-441-5554 and we'll match options in minutes.
What if I do not approve the photos?
Every dollar back. No restocking fees, no return freight charges. Pay first, see your exact unit, ship third — full refund if you do not approve.
Why cheaper than dealer new?
Used OEM from low-mileage donor vehicles. Same engineering as factory new, fraction of the cost. Most dealer prices are 2-4× our pricing for identical parts.

Our 6-Step Inspection & Shipping Process
Every engine and transmission we ship has been through these six steps:
1. VIN-MatchingWe match the donor VIN to your VIN to confirm engine/transmission code, emissions calibration, and drivetrain fit.
2. Tested & VerifiedASE-certified technicians compression-test every cylinder and run leak-down evaluation on engines. Transmissions are Shift-Tested through all gears.
3. Noise & Smoke VerificationUnits are run to verify normal mechanical sound and clean operation — catches internal wear static tests miss.
4. Visual InspectionEvery accessible component is inspected: turbos, manifolds, valve covers, accessories, sensor harnesses.
5. Photograph & CatalogMulti-angle photos sent to you BEFORE we ship for your approval.
6. Palletize & ShipStrapped on a heavy-duty wooden pallet, shipped via freight at no charge.
