**We have CP JE and Wiseco pistons for this kit because there are so many back orders right now and by doing this we can ship an alternate piston that is the same quality to send instead of having to cancel your order.  This is a bolt on kit, ready to drop in with no machining required.  Piston uses pump or race gas.  Everything is new in the original packaging and the original manufacturer's warranty applies*. Negative feedback hurts everyone and in most cases is totally unnecessary. If you have ANY issue with something you order from us PLEASE let us fix the problem before you leave feedback. We 100% guarantee we will find a reasonable solution to any problem. We want happy customers always.  

Please check your order thoroughly when receiving it.  If for any reason at all you are not 100% happy please contact us right away so we can help resolve the issue. Thanks!

*We recommend that this kit be installed by a qualified mechanic with experience working on these types of motors.  Warranty does not include any failure that is a result of improper installation, improper tuning, improper break in, or misuse.  Piston comes with specific instructions for setting the ring gap.  If you do not follow these exactly your motor will fail.  For any warranty to be considered the part(s) in question must first be sent to us and possibly the manufacturer for inspection.  We can not warranty parts based on photos or phone calls alone.
