JE pistons are forged from wrought alluminum alloys. Wrought aluminum is 20% stronger than aluminum bar stock
and 50% stronger than cast aluminum pistons. SRP uses only the highest grade wrought aluminum alloys to make a stronger, lighter piston.
These aerospace quality alloys have been rigourously tested and found to be the most durable material for this application.
To optimize the weight of the piston, application specific forgings are designed in 3D computer modeling programs.
This makes it possible to have consistent dome thickness which will not compromise the durability of the piston.
All JE pistons feature fully CNC machined domes, dishes and valve reliefs to give you precise compression ratios and consistent weights.
All JE pistons incorporate CNC diamond turned skirts to provide you with a better, more consistent finish, and have CNC honed 
pin bores and are thoroughly deburred prior to cleaning and packaging so no prep work is required.
JE pistons are ready to run right out of the box.
