SRP 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 SRP pistons feature fully CNC machined domes, dishes and valve reliefs to give you precise compression ratios and consistent weights.
All SRP 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.
SRP pistons are ready to run right out of the box.
ORDERING NOTE: Pistons are not returnable. Please be sure to check your engines oversize requirements, cam requirements and head and piston to valve clearance requirements before ordering. We recommend that this be done by an experienced and competant engine builder.
