Manley 46115GT-8 4.035" Bore 1.5mm Gapless Top Steel Piston Ring Set

Designed for a 4.035-inch bore diameter, these rings feature a 1.5mm top ring width and a 3mm oil ring width, making them an ideal choice for builds demanding tight tolerances and maximum cylinder sealing efficiency.

Key Features:

• Gapless Top Ring Design: Eliminates the end gap found in conventional rings, dramatically reducing blow-by and improving compression retention under high-load conditions
• 4.035" Bore Diameter: Precision-sized for accurate fitment in applications using this bore specification
• 1.5mm Top Ring Width: Narrow profile reduces friction and reciprocating mass for improved high-RPM performance
• 3mm Oil Ring Width: Effective oil control to minimize consumption and maintain a clean combustion environment
• Steel Construction: High-strength steel provides durability and resistance to the extreme heat and pressure of performance and forced-induction engines
• 8-Ring Set: Includes rings for all 8 cylinders in a V8 application

Manley Performance is a trusted name in professional motorsports, and their piston ring sets are used in everything from street performance builds to all-out race engines. The gapless top ring technology in this set is especially beneficial in boosted applications — supercharged or turbocharged engines — where combustion pressures are significantly elevated.
