⚠️ CRITICAL FITMENT & INSTALLATION NOTICE

📦 THIS LISTING IS FOR 1 PISTON RING SET ONLY (5 RINGS)

• Cummins 6C/6CT/6CTA/6CTAA (6-cylinder): Requires 6 sets for complete engine rebuild

🔧 PROFESSIONAL INSTALLATION REQUIRED: Always verify cylinder bore diameter (114.00mm ±0.02mm), taper, and out-of-round before installation. Check ring end gap per Cummins Service Manual specifications (typically: Top 0.025-0.045", 2nd-4th 0.020-0.040", Oil 0.015-0.035"). Stagger ring end gaps 120° apart. C-Series turbo/aftercooled engines require precise ring seating for optimal compression and oil control under high-load duty cycles. Incorrect installation may cause ring breakage, excessive blow-by, oil consumption, or catastrophic engine failure. Consult Cummins C Series Workshop Manual for exact torque specs, assembly procedures, and break-in protocols.
