  • Flat top design with +.8cc dome volume for precise compression tuning
  • +.020" oversize bore diameter for standard rebuild specifications
  • Designed specifically for Harley-Davidson Evolution 80ci engines
  • Complete piston set for multi-cylinder application
  • Engineered for improved durability and consistent performance

KB Performance Pistons are manufactured to exacting tolerances, offering an excellent balance of performance and reliability for street and mild performance builds. The hypereutectic alloy provides enhanced wear resistance and stable piston-to-wall clearances throughout the engine's operating temperature range.

I purchased "Carrand Whisk Broom 10'' W Label",after exhaustive research for this particular item...they have the BEST/LOWEST COST for this item anywhere!!<br><br>Shipped in a timely manner too!<br><br>Will do business here again in the future,as they have prices that are LOW,plus the great products are found here too.<br><br>Thanks to the staff for a great online shopping experience!

After weeks of shopping around, I was able to find the best price from Autoplicity. The ordering process was very simple since I had the option to pay through my Amazon account. Great experience.

Good company, good prices and great staff.

Wow, not only did I get the best price on the web for a set of Rancho QuickLift and RS9000XL shocks, they were delivered quickly as well. Thanks Autoplicity, I will definitely be shopping with you guys again.

This site was just like shopping at a real store. It was easy to make my order and I was able to do it on the go on my smartphone which is important to me that a site is compatible with handheld. Bravo

Easy

I ordered Thule Aero Blade Load Bars as part of a bike rack for my Infiniti EX35. The part was order on Saturday, 04/14, and arrived at my doorstep on Tuesday, 04/17. And that was by FEDEX Ground shipping. Very very quick, and the right part to boot. Excellent service.

Best price I could find for the brand new name brand product I ordered. Fast shipping as well.

Great price, problem with the manufacturer shipping it out, but was rectified by Autoplicity. Very good follow up customer service.
