Description

The R-3802423 1.00 mm Piston Ring Set is a premium OEM-grade oversize ring set designed for diesel engines that have undergone major cylinder reboring or heavy machining. When the cylinder is enlarged by 1.00 mm , standard piston rings will no longer seal correctly—making this oversize ring set essential for restoring proper compression, sealing, and oil control. Precision-machined from high-strength alloy materials, the R-3802423 ring set delivers excellent wear resistance, consistent ring-to-liner contact, and smoother piston travel. It helps eliminate common symptoms of cylinder and ring wear, including blow-by, oil consumption, smoke, hard starting, and loss of power. This ring set is ideal for full engine overhauls, machine shop rebuilds, and severe-wear corrective repairs. ✔ Key Features & Technical Advantages OEM-spec R-3802423 1.00 mm oversize piston ring set Designed for cylinders rebored or machined 1.00 mm oversize Restores correct compression, oil control & ring sealing Reduces blow-by, oil burning, exhaust smoke & loss of power High-strength alloy rings built for extreme diesel conditions Ensures smooth piston movement and improved combustion efficiency Ideal for full overhauls, in-frame rebuilds & precision machining repairs
