This is a bolt on kit with no machining required.  Piston uses pump or race gas.  All parts are new in the original packaging and the original manufacturer's warranty applies*. 

**Products we sell: At bpratv our kits come with the same brand name parts (in many cases they are better) as other rebuild kits you see online but we always include items no one else does to make sure you get as complete of an order as possible.  We want you to spend as little time having so search for parts as possible.  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.  We have bulk pricing available for every item we sell.  Just let us know how many you need!

Returns: Please check your order completely right when you receive it and let us know immediately if there is an issue.  This 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.
