Where can I read up about setting the gap? If you order new pistons with rings, are they pre-gapped? These are going in a stock motor.

 

If you are running a stock engine then yes, just order rings for the bore size and install them. I'd always check the gap first just in case but they should be fine. File fit rings come larger and are often designated as +5 at the end of the part# or if you have a 4.030 bore a file fit ring will say for a 4.035 bore.

 

great, thanks
