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.

Very simple

Found on Amazon first, decided to go Autoplicity.com website to check price and it was $20 cheaper than Amazon. Part arrived in a couple of days. Fit and worked perfectly.

Good

great service

Overall experience was ok. Got my items at a very great price. Cheapest I found online BUT the shipping was a slight nightmare. Had to call multiple times and items finally got to me but other than I am pleased. I ordered a few days before black Friday/cyber Monday deals so that could've been the problem too. In the end I got what I wanted at the best price!

Is really good and easy to order

Great price easy checkout, looking forward to the purchased product first timer

Great prices, filled and shipped immediately. Best deal around!

Easy and fast

Ordered a Trac-Bar from Autoplicity, and didn't have any problems. WILL be back!

Wow that was fast. I ordered a Pertronix Ignitor conversion kit. Not only were they by far the lowest price I could find, they shipped within hours of submitting the order. I got the shipment in less than 24 hrs, even though I ordered ground shipping. I was a little bummed that they did not offer free shipping, as I am used to with other online places, but with their fast turnaround, I am not begrudging it. Sure it might have been because they have a warehouse nearby, but it was still unexpectedly impressive. The part arrived and looks like it all there and should be good to go. <br><br>I can't vouch for their customer service, but so far I am pleasantly surprised.

Great customer service. Good price. Quick shipment. Would definately reccomend this company.
