Key Features:

  • Forged from dedicated forgings specific to final piston shape for superior strength-to-weight ratio
  • Manufactured in Ohio using state-of-the-art forging presses and CNC machining
  • Includes plasma moly ring package (1/16, 1/16, 3/16 configuration) for excellent seal and reduced friction
  • Pre-gapped rings included for precise fitment and long service life
  • Available in multiple compression ratios to match specific engine requirements

Just order the 1108 turn over ball for 2010 Super Duty and received it within (5) days. Just can't wait to put it on and start pulling the trailer with my new diessel.

Just recieved my order and the pit jug and spout were perfect. The shipping was very fast and it was by far the best price I could get on these products. Autoplicity is great.

Lowest prices around the web and excellent customer service. The only real issue was the wait between placing the order and when it was shipped. Took 4 days but I chalk that up to the large amount of business they due to their prices being so competitive. For the lowest prices that I've seen I didn't mind waiting a bit longer!

Autoplicity is the place to go! I was in the market for a reusable K&N Air Filter and Autoplicity had the best price around (with shipping and handling). My order was filled and shipped promptly, arrived on time, and in perfect condition. Autoplicity kept me up to date with the status of my order at all times until it arrived. I would purchase from Autoplicity again. <br>

Great online shopping. Easy to navigate and order, telling you just how many product are left so you know if you need to buy now. fast processing and shipping too

Great seller! good communication between autoplicity and buyer!<br>Also very quick to process and send out product! Got order within 6 days standard shipping! Will purchase from again!!
