Frank is a great guy and spectacular customer service. He is very knowledgeable and will help explain any questions.
He has a few little tips and tricks he will give you and he will help you do a reed mod if its necessary.

Though I have never had any dealings with him or had the occasion to use his products, he gets consistently great reviews. If I were in the market for rings, he would definitely get my business.

They are the best rings out there by far
he is the nicest off guys to deal with and he has a fast turn around
if you have a problem he is top notch at explaining what and how to correct it
would not use anyone else
money well spent in my book :)

Not to beat a dead horse but I Put a Bowman ring in my DLE 61 today finally lol, this 61 has had about 2 gal threw it so it was not worn out or even close. I measured the stock ring gap and it was .013" there was already signs of blow by on the piston although the motor ran great, When i measured the new ring it's gap was .004" and that was a tight fit with my gauge so i cant wait to break this one in and see how she does.
