Description
Overview:
These Genuine Kohler piston rings are sized .020 in oversize (+0.020 in / +0.508 mm) for K241-series single-cylinder engines, including K241-4600 and K241-4601. Manufactured from durable, engine-grade materials, they restore correct sealing between the piston and cylinder wall after a re-bore, helping to maintain compression and control oil. Correct ring sealing improves starting, power, and fuel efficiency, and reduces exhaust smoke. Suitable for construction and garden machinery powered by Kohler K241 engines, such as lawn and garden tractors, compact industrial equipment, and generators. Supplied to Kohler OEM specification under part number 235289-S for a precise, direct replacement, these rings are engineered to handle high temperatures and continuous service typical of professional and domestic use.
