Another superb product for pro engine builders developed by DRP!
 
These are:
 
GREAT for increasing the compression slightly in U20 engines (10.0-10.5:1 or so depending)
Superior in every way to overpriced cast R16 pistons which raise the compression WAY to much in a U20 and will certainly contact the head unless machined for clearance.  
 
A fantastic stroker piston with slightly increased CR. Minimal or no interference issues with a stock gasket. 
 
Twice the life and durability of ANY cast piston.   Moly coated skirts. Brand new Top quality USA production.
 
 
Rings, pins, circlips included!
 
Note:  these are .040 oversized pistons.  Bore 3.473"
