In the past two years I've have been reading on this board about things and a time or two AA Piston has come up. One time about a pin failure and engine damage. the other question was about heat treating their cylinders. The question I am asking is dose anyone have any comments on their products. Please reply.

I got 4 perfectly round cylinders on the first try, and have been running around on AA 96mm pistons and cylinders for the last 38,000 miles. I'd like to see anyone else who can attest to their durability like that. Some people don't like them because more often than not, you have to go back, and return 1 cylinder a set that isn't perfectly round. Easy to do. Their quality has significantly improved from what I understand.
Every now and then I beat the living crap out of my motor, but most of my miles are freeway miles, at 80mph. No piston and cylinder problems at all. I'm more concerned with my OEM connecting rod bolts/nuts. |

Lots and lots of threads on this.
As long as you can send the ones that prove to be out of round back for replacement, they are fine. That said, I'd rather use KB flat tops and have the stock 2.0 cylinders punched out. In fact, that's what I did. Zach |

I'm using them. 3+ years, about 15K on them. No problems so far. I would recommend them.

I've had AA Cylinders in my car since 2002, but I run KB pistons.
Not too many miles but I have beat the crap out of the motor at the track. (IMG:style_emoticons/default/agree.gif) with above, as long as you check out the 4 you get and can return one (or more) you are set |
