We want you to spend as little time having to search for parts as possible. We always stock the exact same parts from different companies so that when back orders occur we have an alternate part to send that is the same quality.

This would be the ONLY reason your order might be slightly different when it arrives. We have bulk pricing available for every item we sell.

Just let us know how many you need! Please check your order completely right when you receive it and let us know immediately if there is an issue so we can resolve it ASAP. Unless otherwise stated, we stand behind the parts we sell 100%. We ALWAYS STRONGLY recommend parts be installed by a qualified, experienced mechanic.
