SORRY:  We no longer supply rings.

The return and error rate was too high.

Customers did not measure their rings the bore size or look to see if it was a tapered ring prior to ordering. Many aftermarket pistons use different rings and different thickness from rectangle to tapered on one ring only.  We no longer supply Italian pistons as rings are often one year away or never available.   This chart is only to provide customers with some guidance for the description and size of the rings.  The tapered rings were used on original pistons. 

There are many aftermarket pistons that take different rings. 

Each item is a set of rings for one piston only.

Rings listed are for original pistons only.    

with all the rings that did not work out, the back and forth shipping was killing us. It's not cost effective to ship rings back and forth or restock rings, issue credits, incur credit card charges, more transaction fees and double charges to us to return money to credit cards.   For that reason we declared providing rings is a no-win  situation for the customer and ourselves. 

In most cases it is best to replace the piston with a Wiseco piston. The new pistons all come with rings. Rings are available for aftermarket Wiseco pistons.

These rings BELOW  are for the original Chrysler or Force Outboard Motor Pistons.

If you are ordering replacement pistons they already have rings and wrist pins.
