Low Profile Water Neck Kit -20

The Low Profile Water Neck Kit -20 from ALLSTAR PERFORMANCE is a compact, angle-flow coolant inlet solution engineered for Chevy V8 engines where space constraints demand a reduced-height design. This 90-degree water neck serves as the bridge between your engine block and radiator hose, managing coolant circulation while fitting into tight engine compartments common in performance builds, restorations, and stock applications. The low-profile geometry allows builders to route cooling lines without interference from headers, intake manifolds, or custom fabrication obstacles.

Constructed from aluminum and finished with anodized protection, this water neck resists corrosion and oxidation in high-temperature coolant environments. The 20 AN male inlet accepts industry-standard -20 hose and fittings, providing a sealed, leak-resistant connection point. Anodizing extends service life by creating a hard oxide layer that protects base aluminum from coolant chemistry and vibration wear. The kit ships complete with all necessary hardware for direct installation—no additional fasteners or adapters required for basic mounting on Chevy V8 applications.

Engine builders, restoration specialists, and performance enthusiasts benefit most from this compact design when space is premium or when upgrading from stock cooling geometry. The 90-degree flow path works seamlessly in engine bays where a traditional or tall water neck would obstruct header clearance or custom intake routing. This kit is ideal for street rods, crate engine conversions, and Chevy V8 restorations where cooling system modernization meets physical packaging constraints. Verify block and manifold inlet specifications before ordering to ensure compatibility with your specific engine configuration.
