World renowned for our work building race winning pistons, Wiseco utilizes experience from a diverse background of the most sophisticated engines.

Wiseco?s Pro Tru line creates the best value in forged pistons today. These American made pistons are forged and machined by skilled Ohio craftsmen with state-of-the-art forging presses and CNC machines. By using dedicated forgings specific to the final piston shape, Pro Tru pistons are stronger and lighter than industry standards.

Pro Tru sets include plasma moly 1/16, 1/16, 3/16 pre-gapped ring packages which provide excellent seal, friction reduction, and long life. Pro Tru pistons also come in a variety of volumes that allow the engine builder to choose the exact compression ratio required for their engine.

Order # 26695 I ordered an EGT and a gauge pod. It showed up at my house 4 days later exactly as I had ordered it. The Prices are unbeatable!

seemed a bit hard to find products, but the prices were great and delivery prompt

Autoplicity are great! Shipped out my order quick with good prices!

This is the first time I've ordered from this site, but things look good from what I can tell so far. They had the parts I was looking for (including a fairly specialized racing part) for a price slightly lower than other places I had looked, and my order shipped the next business day. At the time I wrote this, they were also offering $5 back on my order for writing a review. ;-)

Thanks for you swift respond for the email and your accurate information and i hope to deal with you again

Great prices and super fast shipping. Good job.

The correct product that I ordered, and easy to find through there web site.thanks

You show Paypal's logo at the bottom of the screen. Yet there is no way to use it on your site.

Cheapest prices I found online! Ordered at 4:30 on a Thursday afternoon and had 'em waitin' on my doorstep by SATURDAY!
