Product Details

The JE Pistons 284780 is a professional-grade forged piston set engineered from 2618 aluminum alloy for extreme performance applications including high compression, forced induction, and nitrous oxide systems. This 4-piston set features a 3.268-inch bore diameter, inverted dome/dish design, 1.165-inch compression distance, and 0.787-inch pin diameter.

Key Features:

  • Application-specific forgings with optimized, uniform crown thickness for consistent strength and heat distribution
  • Contact reduction groove minimizes frictional drag and improves efficiency
  • Accumulator groove increases top ring stability and sealing performance
  • CNC-machined side relief with lower support band for enhanced skirt strength and durability
  • Honed pin bores with double pressure-fed pin oilers for improved lubrication
  • Wire locks included for secure pin retention
  • JE ProSeal piston rings included with each set

Manufactured from 2618 aluminum alloy, these pistons deliver superior tensile strength compared to standard 4032 alloy, making them ideal for racing and high-performance street applications. Recommended ring set: JG1004-3268. Sold as precision-matched sets to ensure balanced performance.

Autoplicity had the exact part I wanted at the best price upfront with no gimmicks or hidden conditions. Prompt shipping at a fair price. Simply excellent!

I was very surprised that even with shipping, I saved 40% over the exact same item at a local auto store. They shipped the next business day and I am expecting to receive within 1 week of placing the order.<br>Autoplicity's website is easy to navigate and the selection and prices are top notch. I will be ordering from here again!

Excellent company. Will do business again. Super fast shipping, great price, and bike rack came in perfect condition.

Very fast shipping! I got an email saying it was shipping 2 days after I placed my order, when I checked the tracking it was already delivered to my house! Will shop again.

A+ part as advertised, quick shipping.
