Description
Overview:
The Ring Set R3 (88.8 mm) Oversize is a genuine M.A.G component for the M.A.G 1057 DRT diesel engine, supplied under OEM No. 9282 036. This precision-ground piston ring set restores correct sealing and oil control in re-bored cylinders sized to 88.8 mm (approx. 3.50 in). Made from wear-resistant, engine-grade metal, the rings are built to cope with diesel compression and heat, helping the engine hold compression, reduce blow-by, and maintain power. Suitable for maintenance and restoration work on the 1057 DRT platform, this is unused old stock from vintage supply, so parts may show light tarnish from storage but remain serviceable. It is a direct-fit, oversize ring set intended for accurate installation during engine rebuilds where an oversize is specified.
