The 944cc high compression piston kit raises the compression ration to 11.5:1 and increases bore size to 944cc.  Pistons are machined from 2618 T6 high tensile forged aluminum and the dome/dish features smooth flowing radii and requires no deburring or preparation before installation.  JE Pistons are specifically engineered to endure extreme applications including professional competition. 

Included with every piston kit are the following JE Piston components:

• 157598 +2mm pistons (2)
  
• 748-2250-14-95C taper wall piston pins (2)
  
• 748-050-MW piston pin clips (4)
  
• XC9400 piston ring set (2)
