CW had problems with their cylinders when they came out, they soon pulled them off the market becasue 3 out or 4 were cracking. CW recenly released the redesigned cylinder. you can get this just for 210 from woodwardspecialties.com you should run a CP piston with the kit. only piston worth running in my opinion. nmotion/ JSR makes awesome jugs. athena also makes a good jug but is .030 shorter and more needs to be takin account for when using one. ice cube/maxpower also just redesigned their jug.
