Pistons & American Cycle Pro Rings 500 62-68 .020 Over JCC EMGO for Triumph
New set of pistons and rings .020 over for a 500 Triumph with a 8:1 ratio. These will work on late non quench band heads from 1969-1973 T100. You may have an earlier Triumph with a late head. You can tell if your head has a chamfer in the chambers. We are selling these with the understanding that the buyer will be having the cylinders bored properly, honed with the correct grit for a cast iron ring (150) and most importantly be sure to thoroughly wash the cylinders with hot, soapy water after machining. These pistons and rings have been used for well over 30 years and are proven to be a great, affordable set. We are not responsible for any errors that may occur in installation, especially broken rings. We are happy to assist you how ever we can in the process. We have top end kits, ring and compressor tools and everything else you may need to do your top end. Please ask for any technical advice you may need.
