Module resale
Every unit here has already proven it works.
We don't sell parts pulled straight off a shelf and hoped for. What's listed here has been through the same bench process we use for repairs — power-up, communication check, and a verified read — before it's ever offered for sale. If it didn't pass, it isn't listed.
- Typical used pull
- No comm check. You find out if it works after it's already in the vehicle.
- Bench Master unit
- Power-up confirmed, communication confirmed, module ID and live data read verified.
- Coverage
- Shipped nationwide from Western North Carolina.

Sequence
How buying here works
-
Find your part number
Cross-reference against your vehicle before reaching out — the same casting can carry different software across platforms.
-
We confirm fit and availability
We'll tell you plainly if it's not a match rather than sell you something that won't work.
-
Ships tested
Every unit that leaves here has already been bench-verified before it was listed — not after you ask.
Questions before you buy?
Send the part number and what vehicle it's going into. A straight answer costs nothing, including when the answer is that it won't work for your application.
