I've been running this set of rings in my imca modified with 13:1 compression. I'm constantly running at 7500 rpms and these rings hold up perfectly. Don't over spend on piston rings, buy these rings, they're a safe bet.
Pros:
  • Strong And Dependable
  • Cost Efficient
Cons:
  • no cons
Yes, I recommend this product.

Yes you need to check the ring end gap when installing any piston rings. Refer to the instructions that come with your pistons for the suggested ring end gap specs. If you do not have the instructions contact the manufacturer of the pistons for a new set of instructions.
