Description

GM Icon Formed Head Relief Pistons are forged from 4032 alloy. With an 11% silicon content 4032 alloy controls the thermal expansion so a tighter piston to wall clearance may be used over a 2618 alloy. The additional silicon also decreases the wear on the skirts and pin bores. This material makes these Icon Pistons ideal for street and mild boosted applications.

Crown and valve reliefs are cnc machined

Top land mini groove technology

Skirts machined by UEM's unique in house built cnc machines

Accumulator groove to help eliminate flutter and maximize ring seal

Skirt and pin boss struts designed to withstand heavy loads from high cylinder pressures

Wrist pins and spiral lock included

1.5mm 1.5mm 3.0mm rings not included

Compression Ratio 64cc 10.4:1

advertised gram weight; 521

Note: Standard bore size is 4.00
