Description
When your engine’s pistons show wear, you’re losing compression, efficiency, and power output. The PROX Piston Kit 01.1346.B restores your engine to OEM specifications with precision-engineered components that match or exceed factory standards. This complete kit gives you everything needed for a full piston replacement—no sourcing individual components separately.
Manufactured in Japan to exacting tolerances, these pistons are cast from high-silicon-content aluminum alloy and CNC-machined for consistency across the entire kit.
