Product Details

The JE Pistons 314451L is a high-performance forged piston engineered for demanding racing and high-output engine applications. Manufactured from 2618 aluminum alloy, this piston is purpose-built to withstand extreme heat, pressure, and mechanical stress found in turbocharged, supercharged, and naturally aspirated race engines.

This single piston features an inverted dome/dish crown design, which optimizes combustion chamber geometry for improved flame propagation and efficiency. The precise forging process ensures tight tolerances and exceptional strength-to-weight ratios that OEM cast pistons simply cannot match.

Key Specifications:

  • Alloy: 2618 Forged Aluminum
  • Crown Design: Inverted Dome/Dish
  • Bore Diameter: 3.661 inches
  • Compression Distance (CD): 1.209 inches
  • Pin Diameter: 0.905 inches
  • Part Number: 314451L

Why 2618 Alloy? JE's 2618 forged aluminum is the preferred choice for forced-induction and high-heat applications. It offers superior ductility and toughness compared to 4032 alloy, making it ideal for engines that see elevated temperatures and cylinder pressures.

With over 70 years of in-house forging expertise and a legacy built on motorsports victories across drag racing, road racing, and circle track, JE Pistons remains the benchmark for forged piston quality and performance. Each piston is manufactured to exacting tolerances at JE's California facility.

you all do fine job Thanks

Very easy to do.

Easy

You had what I needed at a good price. What more can a shopper ask for.

Fast shipping!!!

A little hiccup with finding the rear brake pads for my GS400, after putting the front brake pads for a Supra TT in the cart. Other than having to find the P/N on a different site. I got what I needed.

Thank you!

So far so good...
