**Products we sell: At bpracingatv our kits come with the same brand name parts as other rebuild kits you see online but we always include items no one else does.  We 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.

Returns: Please check your order completely right when you receive it and let us know immediately if there is an issue, that way we can fix it for your ASAP.  We accept returns within the first 30 days for orders sent back 100% complete and all parts brand new, never installed or prepped for installation, in the original packaging.  Parts that do not meet these requirements are not refundable.

*Warranty: We stand behind all parts we sell 100%.  If after installation there is an issue contact us for a warranty return authorization.  We ALWAYS STRONGLY recommend parts be installed by a qualified, experienced mechanic.  Warranty does not cover failure that is a result of improper installation, tuning, break in, or misuse.  For any warranty to be considered the part(s) in question must first be sent back to us for inspection.  We do not warranty parts not installed correctly nor do we warranty anything based on phone calls, photos, or another mechanic's assessment alone

Feedback: Positive feedback is greatly appreciated.  We have changed the way we do business in response to customer concerns and receiving positive feedback when an order goes the way it is supposed to is a huge help.  If you do not feel we deserve positive feedback just contact us and we will do what is needed to help you feel as "positive" as possible about your experience.  Also, we appreciate your feedback to help us improve how we do business.  Please work with us and we will ALWAYS work with you.
