Fishfiles 20,147 Posted June 8, 2020 Welcome to forums , Pronto ---- I think I read a post of yours somewhere else , and you must have a TRX300 Fourtrax FW or A ( utility quad ) as you mentioned putting 25 x10 in the rear , the 300 EX ( sport quad ) uses a smaller tire ----it helps to know what you working on Share this post Link to post Share on other sites

Wheeler 2,527 Posted June 8, 2020 I have an OEM piston in great shape. IF you pay the shipping it's yours. You'll have to pick up some rings for it... 1 Share this post Link to post Share on other sites
jeepwm69 7,721 Posted June 8, 2020 I like Shindy, but wheeler's offer would be hard to beat unless your cylinder has to be bored. I have rarely gotten by with a hone and rings. Normally I've had to bore them with a new piston. 2 Share this post Link to post Share on other sites
