The factory pistons and rods are pretty weak, these were specifically engineered per ZZP's specs for the 1.4 liter LUJ/LUV turbo engine.

These pistons will fit:

• '11-16 Cruze (Gen 1)
• '12+ Sonic
• '14+ Trax
• '13+ Encore

Includes file fit rings.

Product update note February 2023: Our 72.5mm and 73.5mm pistons now feature a deeper (+2mm) and wider (+3mm) valve relief pocket.
