5.4L 4V Modular

We have redesigned and expanded our Ford Modular product line! The new pistons utilize a dedicated Forged Side Relief (FSR) forging that was specifically designed for high horsepower Modular engines. In addition we have found ways to reduce weight and maintain the durability needed for both street and racing use. Lightweight and extremely durable, these pistons are machined for 1.0mm, 1.2mm, 2.8mm and 1.2mm, 1.5mm, 3.0mm rings.

Includes:

  • Pin #866-2250
  • Round Wire Locks (#866-063-MW)
  • Accumulator Grooves
  • Offset Pin

*Rings Sold Separately
