JE Forged Piston Sets
Some specs on JE Zetec pistons. These are available in 2 compression ratios. A regular Zetec is rated at 9.6:1. An SVT is rated at 10.2:1. The below information assumes a regular zetec, so INCREASE the rated compression by approx .5 point if you are installing this in an SVT engine.
JE 298715 - Bore 85mm, Dish. -8.0cc dish volume. 9.0:1 CR. 303 Gram weight.
JE 298716 - Bore 85.5mm, Dish. -8.8cc dish volume. 9.0:1 CR. 310 Gram weight
JE 298717 - Bore 85mm. Dome. 5.0cc dome volume. 11.0:1 CR. 319 Gram Weight
JE 298718 - Bore 85.5mm. Dome. 4.5cc Dome Volume. 11.0:1 CR. 324 Gram Weight
- The Zetec pistons will ONLY work with an aftermarket floating pin type forged rod with a 20mm diameter (take a look at the Eagle rods on this site). They will NOT work with the OEM zetec OR SVT rod.
A word about bore sizes:
- 85mm - a stock Zetec 2.0 found in Focus, Contour, ZX2, etc is 84.8. When overbored .007", this brings the bore to 85mm
- 85.5 - Zetec bore to .027" oversize

- Forged in the USA using 2618 aluminum, yielding high tensile strength needed for high-demand performance applications
- Designed specifically for each engine and use application to provide optimized performance durability
- Proprietary Forged Side Relief (FSR) forging design minimizes friction and power loss with reduced skirt width and saves additional weight with a shorter wrist pin
- Skirt coating (depending on application) reduces friction and wear on piston skirts and cylinder walls while simultaneously reducing operating noise
- Accumulator groove (depending on application) helps reduce pressure from combustion gases, reducing ring fluttering and improving ring seal for consistent power
- Includes high-quality wrist pins, locks, and JE Pro Seal premium piston rings
- Made 100% in the USA
