Sealed Power Piston and Ring Kit
Speed-Pro Digital Diamond Profile (DDP) Hypereutectic Pistons w/Moly Rings
About Speed-Pro Digital Diamond Profile (DDP) hypereutectic pistons:
These
Speed-Pro Digital Diamond Profile (DDP) hypereutectic pistons feature a
new digital actuated diamond turning process that produces precision
skirt profiles. This new Digital Diamond Profile (DDP) technology
creates a unique barrel profile of the pistons, promoting an oil wedge
between the piston skirt and the cylinder wall. They feature a newly
designed ring groove geometry using Thermal Arching Compensation (TAC)
that machines the piston ring grooves with an uptilt to offset thermal
arching distortion. This squares the ring face up to the cylinder wall
for increased power and decreased oil consumption. The Speed-Pro
Digital Diamond Profile hypereutectic pistons feature the next
generation of Duroshield skirt coating, reducing friction across the
entire rpm range and increasing wear resistance for longer life and
superior noise and vibration reduction. They also use precision-machined
piston pin bores that allow for either fixed or floating wrist pins.
The pistons come weight-matched to a 4 gram (+/-2 grams) maximum
variation within every engine set.
