Piston and Ring Set (86.00 mm STD) for Mazda E2200 & Kia Besta R2 Engine (1986-1992)

Heavy-duty piston and ring set with a Standard (STD) 86.00 mm diameter, specifically designed for "Old Type" R2 diesel engines found in Mazda E2200 and Kia Besta models (1986-1992). These pistons are manufactured from high-grade thermal-resistant alloys to withstand the mechanical stresses of commercial diesel operation. Precision-machined to match original factory specifications for pre-combustion chamber designs. The included ring set provides a superior seal, restoring original engine compression and preventing oil consumption in classic R2 engine overhauls.
