Arias 10.46:1 piston (Old Design)

$480.00

This is Arias's old design. I will keep these up until I hear they are discontinued in case anyone needs replacements or has already planned their build around these pistons. If you are planning a new build though I suggest you check out the pistons labled (New Design) as they are greatly improved. 

 

This is advertised by Arias as 9:1 but their numbers are off.
Below is a chart of compression ratios for quick refrence however it's always best to calculate your own for your build.
