**Products we sell:  At bpracingatv our kits come with parts from the best brands in the industry.  What makes our kits different is they are always more complete than our competitors'.  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!

Returns: Returns are accepted within the first 14 days from the date of purchase.  Any return due to changing one's mind will be subject to a 15% restocking fee, so please make sure this is what you want and you have a qualified mechanic to install it.  Return shipping costs are the buyer's responsibility.  Buyer is also responsible for ensuring parts are returned to bpratv in the exact same condition as they were received, which is brand new in the original packaging.  Any part returned that is not 100% complete or is not brand new sealed in the original packaging will not be refunded.

Warranty:  The parts included in this kit are all the best available on the market, and they have been proven over and over again.  This is a high performing engine kit that must be installed and tuned by a qualified, experienced mechanic.  The person who builds this engine is responsible for making sure it is done correctly,  These parts do come with a warranty and if one fails and it has nothing to do with improper installation, tuning, break in, or misuse we will warranty it.  For any warranty to be considered the part(s) in question must be sent to us for inspection.  We do not warranty parts based on phone calls, photos, emails, another mechanic's or another company who competes with us, or any other person's opinion.  95% of all warranty claims result because the piston ring gap was not set properly, no exaggeration.
