Clevite 40451.030 Premium Chrome Piston Ring Set 4.030" Bore

The Clevite 40451.030 Premium Piston Ring Set is a high-quality chrome ring set designed for universal applications including small block Ford, Chevrolet, and Chrysler engines. This set is precision-engineered for engines with a 4.030-inch bore diameter, which is a .030-inch oversized bore commonly used in engine rebuilds and performance builds.

Chrome Ring Technology:

This premium ring set features chrome-plated top compression rings that deliver exceptional durability and wear resistance. The hard chromium electroplating creates a surface that resists abrasive wear and will not flake off, even when exposed to high vibration and detonation. Chrome rings are particularly beneficial for engines operating in dusty or dirty environments, as they are harder and less porous than moly rings, providing extended service life under harsh conditions.

Key Features:

• Premium chrome-plated compression rings for superior wear resistance
• 4.030-inch bore size (.030-inch oversize) for rebuilt engines
• Exacting tolerances that meet or exceed OEM specifications
• Excellent resistance to thermal and mechanical loads
• Low cylinder wall wear characteristics
• Ideal for dusty operating conditions and heavy-duty applications
• High-quality construction from Clevite, a trusted name in engine components

Application Notes:

This ring set is compatible with various small block engine families including Ford 289/302/351/400, Chevrolet 327/350, and Chrysler 360 engines that have been bored .030-inch oversize. Chrome rings require proper cylinder wall preparation and finish for optimal seating and performance. They excel in applications where durability and wear resistance are priorities, particularly in demanding operating environments.
