LS1 Valve Cover Spacers (Pair)

The YELLA TERRA LS1 Valve Cover Spacers are a precision-engineered pair designed specifically for GM LS-series engines. These aluminum spacers elevate the valve covers 0.984 inches, creating additional clearance for intake manifolds, headers, or custom engine bay configurations while maintaining proper sealing integrity through integrated O-ring seals. This is an essential modification for builders working with LS engine swaps or performance upgrades where factory valve cover height conflicts with modern fuel injection systems or aggressive intake designs.

Manufactured from aluminum in natural finish, these spacers deliver a lightweight solution without sacrificing durability. The 0.984-inch height increase is a proven dimension that resolves common fitment issues in LS engine installations without requiring extensive engine bay modifications. The included O-ring seals ensure oil-tight sealing between the cover and spacer interface, while the complete hardware package (bolts and fasteners) allows for straightforward installation without sourcing additional components. The spacer design maintains symmetry across both valve covers, preserving engine bay balance and appearance.

These spacers are ideal for LS engine enthusiasts, street rod builders, and performance engine builders tackling intake manifold compatibility, turbocharger installation, or custom fuel system routing. Whether you're completing an LS swap in a classic car or optimizing a modern LS-powered platform, valve cover clearance is a critical constraint that often determines whether premium intake options can physically fit. The YELLA TERRA pair solves this decisively. Installation takes roughly 30 minutes per side, and the natural aluminum finish integrates with both stock and modified engine appearances.
