What size are the rings in item number 941885? I have now ordered 2 of them that are the wrong size. I need 0.010 for a 1959 Willey Jeep.

Willys Jeep Parts Tech:
STD size for a bore 3.125

hallo, my piston has 4 groove - - there is 4 piston rings on every piston, Do you offer this kind of piston rings ?

Willys Jeep Parts Tech:
The top groove is a heat dampener and doesn't take any rings.

I've measured my pistons and they come up as 3.134 does this mean I have .010 oversize pistons and do I buy .010 piston set rings because I don't see any available only .020 or above . Do you have .010 sets

Willys Jeep Parts Tech:
Email your cylinder wall measurements and i can go from there to help you out determine the size you need.

Hi, this is a set of three rings per piston, my piston has four rings, do you have a set for four rings pistons ? Are they Hastings ? Thanks.

Willys Jeep Parts Tech:
The top groove is a heat dampener and doesn't take a ring.

My Machinist is asking what type of rings I am going to purchase. He said it makes a difference as to the finish he puts on the cylinder walls. Can you tell me?

Willys Tech:
These are made in the USA and made in high grade grey iron castings (cast iron).

Just going to hone cylinders then replace rings and rod bearings on stock 63 cj5. Is standard size the right choice for both?

Willys Tech:
It depends on the condition of your cylinder walls and the machine surface on the crankshaft. You will need to inspect for wear and we have stardard as well as oversizes.
