What piston is best.

[jsmith2232]

I am going to put a piston and stage II hotcam in the 400 ex listed in my sig. If i am using the stock bore how much compression can i use reliable and would you go with a wiesco, ross or je?

[C&SRACIN426EX]

I would go with je. Ive been running them for a while and they hold up really good.

i've been using a je as well for 2 years of dune riding, still running strong porbably going to re-build it soon b/c im bored though

[Colby@C&DRacing]

in the 400ex I would recommend the JE or Ross piston
