Description

The R-3802422 0.50 mm Piston Ring Set is a premium oversize ring set engineered for diesel engines requiring corrected piston-to-liner clearance after cylinder wear, honing, or machining. When a cylinder has been machined 0.50 mm oversize, these rings are designed to restore proper sealing, stable compression, and optimal oil control. Manufactured from high-strength alloy steel and precision-cut for perfect ring-groove fitment, the R-3802422 oversize ring set ensures smooth piston movement, cleaner combustion, and long-term reliability. It eliminates common symptoms of worn rings, such as blow-by, smoking, oil consumption, low compression, and power loss. This oversize ring set is ideal for in-frame overhauls, full engine rebuilds, and professional machining repairs—ensuring OEM-level performance even under extreme diesel operating conditions. ✔ Key Features & Technical Advantages OEM-spec R-3802422 0.50 mm oversize piston ring set Designed for cylinders machined or bored 0.50 mm oversize Restores correct sealing, compression, and oil control Reduces blow-by, oil burning, exhaust smoke & hard starting Precision-engineered rings ensure perfect groove fitment High-strength alloy construction designed for extreme durability Ideal for diesel engine rebuilds, in-frame repairs & machining operations
