A molded-rubber valley cover gasket built on an aluminum carrier, designed as an OE-style replacement for 11-bolt GM LS2, LS3, LS7, and LSX valley covers. The molded rubber seals tightly against the block to prevent oil leaks, while the rigid aluminum backbone maintains proper shape and clamping load. Suitable for stock rebuilds or performance engine work where reliable sealing is essential. Directly replaces GM part numbers 12574467 and 12610141.
