Why Buy a Recommended Alternative?Help

What's a recommended alternative part?

A recommended alternative part is an item that can be crossed over from an original equipment manufacturer (OEM) part. They are also known as "aftermarket" or "replacement" products. These parts are usually less expensive than the OEM but meet or exceed OEM standards for quality and performance.

We stand behind the quality of the recommended alternative products we sell. If you the product you purchased did not properly replace your OEM part requirement, please let us know.
