Resolved What is 6-bolt piston ring size?

This site may earn a commission from merchant affiliate links, including eBay, Amazon, and others.

stock bore is 85 mm in all 4g63's. over bore usually goes by .5mm up to 86.5mm. Each .5mm is .020" in standard.... anyway LOL yea I've never used them personally but Wiseco is a good brand and Extreme wouldn't sell crap.
 
You need to check the ring set size for the stock pistons and the wisecos

But why do you want to spend $100+ on the wiseco rings for stock pistons?

The $40 NPR rings will fit
 
You may want to click on the market place tab and check the vendor reviews on that vendor, or do a search before you place your order.

I would suggest you do that with any vendor or member you want to place an order or make a deal with.
