Manley 462484-8 Groove Lock Piston Ring Spacer Set 4.060-4.080 Bore

The Manley 462484-8 Groove Lock Spacers are precision-engineered piston oil ring spacers designed for high-performance engine builds with bore sizes ranging from 4.060 to 4.080 inches. This set includes 8 spacers with a 3mm width, providing complete coverage for V8 engine applications.

These spacers feature Manley's radial tension design (RTD) technology, which represents a modern advancement over traditional dimpled-style spacers. The RTD design allows the groove lock spacers to snap securely into a receiver groove machined within the oil ring groove of compatible Manley pistons. The radial tension prevents rotation during engine operation, ensuring consistent performance and reliability.

Key Features:

• Fits bore sizes from 4.060 to 4.080 inches
• 3mm width for proper oil ring spacing
• Radial tension design prevents spacer rotation
• Snap-in installation for secure fitment
• Designed for use with Manley pistons featuring receiver grooves

These groove lock spacers are essential components for proper piston ring installation and function, particularly in high-performance and racing applications where precise oil control is critical for engine durability and power output.
