### ⭐⭐⭐⭐⭐ Perfect

### ⭐⭐⭐⭐⭐ The best rings ever at budget price
*by C***E on January 14, 2025*

I rebuilt a Ford 235 V8 motor for my Sea Ray 21' cuddy cabin boat. Done a complete rebuild down to the block. Used these piston rings, they were gaped perfectly, and first start up and break in no blue smoke and the rings sealed perfectly. Highly recommend these for just a regular rebuild on a motor.
