EDR Performance ZX6R ZX636 Forged Piston kit 2013-2024 high compression 67mm or 69mm

EDR Performance ZX6R & 636 custom performance and racing piston kits EDR Performance the leader in ZX636/ZX6R performance and race engines is pleased to announce our specific designed high compression piston kits, custom made to our specification by the world leader, CP Pistons USA.  Unlike others that just simply wanna sell you an "off the shelf" piston kit, we have spent many years fine tuning our design. Our piston kit is not only slightly lighter than off the shelf, we also up the compression ratio to what we have found works perfect!  These pistons (Std bore 67mm) can be run with PUMP 92 octane fuel with standard cylinder head and even larger gains can be had when cylinder head is further machined for even more compression. Then if you add our EDR Performance Billet ZX6R camshafts you will have a massive gain in power and acceleration! Our pistons also allow room for our camshafts as off the shelf pistons will compromise piston to valve clearance if running our camshafts.
