Your cart is empty. Replacement free piston kit for KYB AOS Twin Chamber forks. Made of light weight aluminum, much more durable than the Factory plastic piston that is susceptible to cracking. STD piston mimics the Factory suspension feel. Plush piston provides a softer smoother feel throughout the suspension stroke.

Install added no extra difficulty to a routine fork rebuild. Mated up to the OEM KYB components perfectly, and rides fine. I bought these for a set of used '09 YZ250F forks that I had purchased that already had a busted plastic free piston, so I can't speak for how different the forks ride before vs after installing the Zeta free pistons, but I love how it rides now and this is what's inside. Good reassurance that they won't break since aluminum is far more stout.
