AutoTec "Shelf" Pistons
ZSR Engines is a wholesale distributor for RaceTec and AutoTec pistons. RaceTec pistons are 100% made in the USA and are forged out of 4032 alloy (perfect for NA or light power adder). We have the ability to change ONE dimension of the shelf part like Compression Height, Bore Size, or Ring Package. This is basically like getting a CUSTOM piston at a shelf price.
These pistons are available for a ton of different head configurations: Inline, Twisted Wedge, Cleveland, etc
All AutoTec pistons feature:
-Diamond turned skirts
-1.5mm-1.5mm-3mm ring grooves standard (can be changed at NO cost)
-Double Pin Oilers
