Jeep 4.0L Stroker Forged Pistons - 9.3:1 Compression Ratio By Icon (IC944)

United Engine & Machine's Icon piston line is engineered from the ground up for extreme high performance street or racing applications. We're putting a century of piston design and experience into every Icon piston and it shows. No matter your high performance application, there is an Icon piston for you.

Each Icon piston is forged from high-strength, heat treated, 4032 aluminum alloy. This makes Icon pistons significantly lighter than the competition without sacrificing strength. Our lightweight design will allow your engine to rev quicker and get into it's power band faster. The V-rib design promotes maximum piston cooling.

Icon pistons include many racing features such as diamond-machined skirt, head, mini-grooves, pin bore, gas accumulator, ring grooves, and pressure-drilled pin hole oiling.
