I bought this for a repair project on an older Silverado. The biggest thing I wanted was proper fitment, and this delivered. Once the old rusted section was removed, getting the replacement positioned correctly was straightforward.

My truck had the typical rust problems underneath, and the original fuel tank support was definitely past its prime. This replacement gave me a much better starting point for the repair and fit where it needed to. Very pleased with the finished job.

There is nothing fun about dealing with rust underneath an older truck, but having a properly shaped replacement makes the job much less frustrating. This crossmember was exactly the type of part we needed for the repair.
