**Products we sell: At BPRATV we stock the same parts from different manufacturers 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 NEVER sub a cheaper part and charge you the same price, EVER.

 *Warranty: If after installation there is an issue contact us for a warranty return.  This product is NOT DIY.  Over 99% of people in the world are not qualified to build an engine, and it is the responsibility of the person assembling and tuning the engine to make sure everything works correctly.  It requires special tools and has to be done 100% correct.  Many parts must be measured down to .01”.  We ALWAYS STRONGLY recommend parts be installed by a qualified, experienced mechanic.  STUD WARRANTY: If for any reason a stud fails during use, not installation, we will send a completely new stud kit.  No other parts or any labor are included, and it can not be converted to a refund or discount on any order.  Any part(s) for which a warranty claim is made must be sent back to us for inspection, NO EXCEPTIONS.  We can not warranty anything based on photos, emails, phone calls, or what you read online alone, and we do not warranty anything based on what another mechanic says the problem is.  We stand behind what we sell, but there is a process that must be followed for warranties.

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 want information from customers when their experience is less than desirable so we know what areas need improvement the most.  Please work with us and we will ALWAYS work with you.
