Speed Pro R-9342 35

Speed Pro R-9342 35 is a file-fit piston ring set for V8 engines. The set uses plasma-moly rings with standard tension and is intended for accurate ring-end-gap fitting during engine assembly.

Application / fitment

R-9342 35 is used in 8-cylinder engines requiring 4.030" / 102.36 mm rings and a 1/16", 1/16", 1/8" thickness layout. It should not be selected by vehicle model alone; piston groove sizes and final cylinder bore are the controlling dimensions.

• part type: piston rings
• V8 / 8-cylinder engines
• diameter: 4.030" / 102.36 mm
• type: file-fit
• material / coating: ductile iron, plasma-moly

Before installation, fit each ring to its cylinder, check end gap, ring orientation and piston groove cleanliness. File-fit sets require manual ring-end finishing to the clearance required for the specific engine build.
