Arias Forged Piston Kit – Nissan RB25/RB30 20-over
 |
|
This Arias piston kit features CNC-machined 4032 alloy pistons, which provide superior heat control with less expansion. That allows you to run tighter clearances for superior ring control and piston stability. And with the matching piston rings that Arias included (moly-faced alloy steel for turbo vehicles and chromemoly faced ductile iron for non-turbo), you get excellent protection against high heat and oil blowby. Arias even threw in case hardened, high carbon steel wrist pins to complete the kit.
These pistons are custom made by Arias to suit the Rb25 head with RB30 bottom end engine setup.
