Can't absolutely answer but probably yes. I assume you are going oversize for a reason and when you go oversize you need to have the cylinder bored to the piston (take both to the machine shop). If it was already oversize and you are just replacing the piston you might not need to bore the cylinder but, on a golf cart, then why would you be replacing it? Mine was so worn that I had to go 2x over and, obviously, was the reason I was replacing the piston (very worn). On a side note. The first piston I got had the wrong rings in the box (the piston was machined for chamfer rings and came with non chamfer) . BU replaced them for free and quickly but figuring out why they didn't compress all the way into the grove took some time. Before trying to install make sure your rings will go all the way into the grove (flush with the piston) and not stick. Good luck!!!
