I don't think you'll find a better price and the quality is good, much better than what I expected. You get both ends with plenty of wire in between. You can use it as an extension or cut it in half and use one or both ends. I only needed the vehicle end, but now i have a spare, for another trailer or if one goes bad. I would certainly but it again. ... show more

Good quality wires, nice long extender. I destroyed my old connector so really got this to replace it vs extend it but it works well.

    • Quality 4 Pin Trailer Connector/extension
These are quality 4 pin trailer connectors. I only needed the female ends, but for the price, it was worth the purchase just to get the one end.
