    Rings for Pro Circuit Hi Comp piston

    by Cjoecruz003 » Tue Jun 10, 2014 10:50 am

    I want to replace my rings but read (on another forum...sorry) that the PC pistons are made by JE but the rings are OEM... This individual tried both JE and OEM rings but were too thick for the PC piston (this was for an 08 250r btw). I have an 05 450r. Could anyone with this PC piston verify the 05 OEM rings will fit?

    JE makes PC pistons but they make them to PC's specifications. We have not attempted to fit non PC rings on PC pistons so I can't address your question. However, I recommend getting the PC rings. The piston is not the place to experiment in my opinion.

    I agree, I wouldn't force rings that wouldn't fit on a piston especially the PC one I have...kinda pricey! The issue was that the rings both JE and OEM were too thick for that year. The OEM rings that fit was found later under a different part number since it was from 06-07 piston not the 08-09 and apparently the rings were thinner. Just wondering if that's the same issue with the 05 450s

    haven't done any measurements on rings/pistons to determine what model year will fit what year of the OEM or other pistons. i recommend just getting the rings that were designed for the piston you want to use.

    Sorry for any confusion but like I said before I came across info that PC piston kits use OEM rings. Someone had an issue with using OEM rings on his 09 250r with a PC piston. He also tried JE rings since JE manufactures PC Pistons and those were too thick to fit in the piston grooves. So he had to order OEM rings from a different year, just wondering if this issue would come up on a 05 450.

    I called Pro Circuit (No automated BS, No 1hr wait, someone picked up after a few rings!) and got the verification that they do use OEM rings in their piston kits and there shouldn't be any fitment issues with the 05 450s. Problem solved :D
