I have 030 rings but need to close the gap. which is the next biggest ring size 040 or 020 ? Not sure which way the numbers go . basically I need the next bigger rings than 030. Many thanks.

Willys Jeep Parts Tech:
.040 is the next size up.

I am rebuilding an F block engine for a CJ3b. Are these cast iron piston rings (Item # 941888)? Do you have cast iron piston rings? The machinist I am working with has told me to buy cast iron piston rings.

Willys Jeep Parts Tech:
Yes, these are cast iron.

I just need rings for one piston, what would be the pricing for that if thats available or an option?

Willys Tech:
Sorry, we only sell them in complete sets.
