World renowned for their work building race winning pistons, Wiseco utilizes experience from a diverse background of the most sophisticated engines in such venues as Formula 1, Indy Racing League (IRL), NHRA Pro Stock, Moto GP, AMA Superbike, AMA Motocross and Supercross to design and manufacture the highest technology pistons available.

Features

  • Valve Pocket designs that allow maximum flow around valve, also allowing oversized valves and high lift cams to be utilized.
  • Piston Crown shapes designed to promote maximum Intake Charge efficiency through scavenging mixture ?Cross Flow? during intake and
    exhaust valve overlap. More fuel and air equals more horsepower!
  • Piston Domes designed for optimal quench during the compression/ combustion cycle, resulting in resistance to detonation and preignition.
    The end result is longer engine life and increased horsepower potential.
  • Precision machined ring grooves with proper orifice/accumulator volume feature calculated groove root diameters and axial widths, providing
    excellent surface finish and flatness, maximum ring seal and minimized blow-by and oil consumption.
  • World class, ISO Certified, forging facility that utilizes the latest technologies ? Featuring complex forged shapes, advanced materials, and feature-aligned grain flow technology.
  • Complex Piston skirt profiles that reduce power robbing friction, yet promote stability in the bore for optimum ring seal.

ArmorGlide Skirt Coating
Wiseco?s new ArmorGlide skirt coating is the result of testing, development, and benchmarking through our in-house dyno program. The outcome ? minimized friction, maximum horsepower, and improved wear resistance.

Not only is ArmorGlide a high-tech lubricant that reduces friction, but it also allows the piston to be fitted tighter within the bore than a non-coated piston. Better ring seal reduces noise from piston rock. ArmorGlide is being applied to selected pistons.

Great site!

Great, except I ordered 2nd day air and got it in 5 days, hope im getting reimbursed for shipping.

The tailgate liner I received for my 2001 Toyota Tacoma was shipped fast and received in perfect condition. It fit my tailgate perfectly and covered the top rail. In fact it exactly matched the original liner that was installed in 2001 but had accidentally been damaged. I had given up trying to find a new one until I saw this one from Autoplicity.

Quick and easy ! Highly recommend !!!!

EASY ORDERING

Very fast shipping

Same day shipping....is there anything better? Good job guys!

This is my first time ordering from Autoplicity and there's a good reason part of simplicity is the name. I buy stuff online all the time an this website is definitly easy to navigate. The price was resonable and shipping turnaround was fast.

Autoplicity had the cheapest price, I got my order in 3 business days, and let me know through email when they received my order, shipped my order, and completed my order. Was really impressed!

Great site. Provided needed technical specs. Shipped promptly. Although I had to ask for the tacking number, it was not emailed, one was provided promptly upon request.

Awesome price on a name brand part. Good communication too. Many payment plans and you can use your PayPal !!

I was searching for brake rotors on the Internet for over 3 hours tring to find the best prices-- Autoplicity beat everyone hands down! The best deals out there. Quick response and my order shipped within one business day! Bravo. <br><br>Their website could be improved by auto selecting make/model combinations. I had to double check the part numbers for the pads..they matched the rear pads with the front rotors. I only caught this due to the fact that the pads were extremely cheap..too cheap. The low price was for the rear set as front pads usually at more expensive due to their larger size.

Very easy order to place, can't wait to get my part in!!thanks

I couldn't find this in stock anywhere! Not only did Autoplicity have it in stock they were about $10 cheaper than any other sites list price. Received the package very fast! Will use Autoplicity for all of my part needs!
