Enginetech M10328-040 piston rings give engine builders a complete premium ring set for GM 6.2L 376 ci V8 builds machined 0.040 in. oversize. Sized for a 4.065 in. base bore, this set helps restore cylinder seal, control oil, and reduce blow-by after boring, making it a smart choice for a fresh rebuild instead of reusing tired sealing hardware.

Enginetech M10328-040 Technical Specifications:

• Complete engine ring set is sized for all cylinders in a GM 6.2L 376 ci V8 build requiring 0.040 in. oversize rings.
• 1.20 mm top compression rings and 1.50 mm second compression rings help rebuild proper combustion sealing when the finished bore is within specification.
• 2.50 mm oil rings are designed to manage oil on the cylinder wall and help limit oil consumption after break-in.
• Manufactured to SAE-guided dimensions for consistent fit in precision-machined cylinders.

Includes:

• Complete piston ring set for one engine

Verify the finished bore with a precision gauge before installation. Ring end gaps must be checked and file-fit to the engine builder's specification to help prevent blow-by or ring-end butting.
