**Products we sell: At BPRATV we sell parts from the best names in the industry.  Unless otherwise stated, we will put the quality of the parts we sell up against any other companies’ in the industry.  Also, we stock the same parts from different manufacturers so that when back orders occur like they have been for the last year 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: We accept returns within the first 30 days from the date the item was shipped.  You can return part or all of your order.  All claims for orders sent incorrect, incomplete, or damaged should be made right away by contacting us.  99% of problems can be easily solved without returning the entire order.  Orders returned due to “changed mind” or “parts not needed anymore” are subject to a 10% restocking fee plus a deduction for our cost shipping the order to you.  Any part to be returned must arrive to our facility 100% complete, and all parts must be brand new, never installed, in the original packaging, to receive a refund for them. It is the buyer’s responsibility to ensure returned parts arrive to us in the same condition they were when they left our facility.  Any item returned that does not meet the above conditions will not be refunded.  For more info about returns see the eBay Return Policy. 

 *Warranty: This product is NOT DIY and it is the responsibility of the person installing and tuning the parts to ensure they work correctly.  Over 99% of people in the world are not qualified to work on an engine, and 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 new, complete stud kit.  No other parts or any labor are included, and it cannot be converted to a refund or discount on any order.   ALPHA CUB WARRANTY: If your Alpha Cub cylinder fails it will be repaired or replaced free of charge.  Warranty for all products we sell 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 based on phone calls, photos, emails, what you read online, 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 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.
