Product Details

The JE Pistons 314674 is a forged piston set engineered for high-horsepower Modular Ford engines. Built from 2618 aluminum alloy, these pistons deliver an exceptional combination of strength, durability, and reduced weight — making them an ideal choice for performance street, track, and forced-induction applications.

JE's Modular Ford piston line uses a dedicated Forged Side Relief (FSR) forging, a design specifically developed to handle the extreme cylinder pressures found in high-output builds. The FSR forging reduces piston weight while maintaining structural integrity under demanding conditions.

Key Specifications:

  • Alloy: 2618 forged aluminum
  • Bore Diameter: 3.572 inches
  • Compression Distance (CD): 1.320 inches
  • Pin Diameter: 0.866 inches
  • Dome Style: Inverted Dome / Dish
  • Set Quantity: 8 pistons

Key Features:

  • Forged Side Relief (FSR) design for reduced weight and improved strength
  • Machined for modern 1.0mm, 1.2mm, 2.8mm ring pack configurations as well as 1.2mm, 1.5mm, 3.0mm ring packs
  • Inverted dome/dish crown geometry optimized for compression ratio and combustion efficiency
  • Designed to withstand the rigors of supercharged, turbocharged, and naturally aspirated high-horsepower builds
  • Precision CNC machined to tight tolerances for consistent fit and performance

Whether you are building a naturally aspirated stroker or a boosted Modular Ford powerplant, the JE Pistons 314674 set provides the reliability and performance margin serious engine builders demand.

Great

Very competitive pricing and non-ridiculous shipping prices. Sometime they don't have what I need in stock, or enough of what I need, but overall, very happy with their service.

very easy to shop Thank You

Great seller. I ordered a banks intake system for my 2001 silverado and I recieved exactly what I ordered. I'm very happy with this seller as a matter of fact I would be ordering my exhaust system from them. Besides they had the best price

I searched the internet high and low for the JKS Quicker Disconnects and almost thought it was a scam when I found them for this price! The order was simple and the shipping was fast. I could not be happier!

Made an order and 2 days later got an email saying it was canceled. Picked up the phone and it was resolved quickly. Product is now in the mail. Prices are great.

I was skeptical about Autoplicity since I hadn't heard of them before, and that their price was 12% lower than anyplace else I could find. Plus, I couldn't even find a store around here that carried the X-jack. Plus I got it delivered right This my door fast. You people are Excellent!

Fast

The prices are great. Shipping is so so, but that's normal for Alaska

Not sure why I had to pay tax, but very good price.

Easy to use site with the items I wanted!

SMOOTH

quick and easy
