This is a 19-inch by 8.5-inch OEM (Original Equipment Manufacturer) aluminum alloy wheel rim in a Hyper Silver finish, built for the 2018-2019 Cadillac XTS. It uses a 5x120 bolt pattern with a 5-spoke design. Offset is 39mm.
Identifying This Wheel
This wheel was originally manufactured under multiple factory part numbers including 23372449 and 23372450. These numbers are typically stamped on the back of one of the spokes — if your wheel shows any of them, this is the correct match. The interchange reference number is 4818, which is the universal cross-reference used across the wheel industry to identify interchangeable wheels.
Our Remanufacturing Process
Every wheel we sell starts as a take-off from auto dismantlers across the country. We inspect each one for cracks, bends, and structural damage. Repairable wheels are stripped, straightened on a calibrated rim straightener, machined as needed, and refinished to match the original factory specification. We don’t resell wheels that fail our structural inspection — cores that can’t be brought back to OEM standards are scrapped.
Shipping and Stock
We stock inventory at six US warehouses: Dallas, Houston, Los Angeles, Philadelphia, San Antonio, and San Francisco. Finished wheels in stock ship the same business day. Wheels that need refinishing are completed by our overnight crew and ship the next business day, so even when a finished wheel isn’t on hand at your nearest warehouse, you’re looking at one extra day at most. Most US addresses receive delivery within 1 to 4 business days via FedEx Ground.
