TOTAL SEAL CR3690 5 Classic Race Piston Ring Set

The TOTAL SEAL CR3690 5 Classic Race piston ring set is designed for engines with a 4.000-inch bore. This file-fit set features 1/16-inch, 1/16-inch, and 3/16-inch ring thicknesses for a configuration suited to performance engine applications.

Each ring set uses ductile iron construction with a plasma moly facing. The standard-tension design provides a defined ring package for applications requiring these specifications, while the file-fit format allows the ring gap to be adjusted during engine assembly according to the builder’s requirements.

This kit is configured for an 8-cylinder engine and is identified by part number CR3690 5. The TOTAL SEAL Classic Race series offers a focused piston ring solution for builders selecting ductile iron rings with plasma moly treatment and standard tension.

The set is listed as not air restricted and not truck-freight-only. Verify bore size, ring thickness, tension, and cylinder count before installation to ensure the set matches the intended engine application.
