JADSOrBoBi Thermostat Housing Spacer for Brodix HV & Chevy SBC/BBC V8 — 1" Anodized Aluminum with 2x 3/8" NPT Ports

JADSOrBoBi 1" thermostat housing spacer raises the water neck for improved clearance and adds two 3/8" NPT female ports for plumbing flexibility on Brodix HV series and SBC/BBC V8 engines.

This lightweight aluminum water neck spacer fits between the intake manifold and thermostat housing to create one inch of additional height, easing clearance for carburetors, fuel lines, or custom plumbing. Anodized for corrosion resistance, it comes with an O‑ring and two 3/8" NPT female ports so you can add temperature sensors, bypass lines, or coolant fittings without tapping the head or manifold. Designed to be a straightforward, durable solution for Brodix HV series intakes and common SBC/BBC V8 configurations, it’s a practical part for builders, hot rodders, and engine tuners.

How does the spacer improve clearance under the intake manifold?

Adding one inch of spacer thickness lifts the thermostat housing and water neck away from the intake, creating room for taller carburetors, fuel rails, or ignition components. This prevents interference and simplifies routing without modifying the intake or cylinder heads.

• 1" thickness increases vertical clearance at the water neck mounting point
• Anodized aluminum keeps weight minimal while staying sturdy
• Compatible with Brodix HV series and common SBC/BBC bolt patterns

What plumbing and sensor options does the spacer provide?

Two 3/8" NPT female ports allow easy attachment of temperature sensors, pressure taps, or auxiliary coolant lines. Using the spacer’s ports keeps fittings centralized at the intake area and avoids drilling other components.

• Two 3/8" NPT female ports for sensors or fittings
• Ports accept standard automotive temperature senders and adapters
• Preserves original thermostat housing integrity—no head tapping needed

Will this spacer fit my engine and how easy is installation?

The spacer is machined to match Brodix HV series intake manifolds and common SBC/BBC V8 thermostat housing bolt patterns. Installation is a simple sandwich mount using the included O‑ring and existing hardware; always confirm pattern and clearances before fitting.

• Designed for Brodix HV series intakes and SBC/BBC V8 compatibility
• Includes O‑ring for a reliable seal between manifold and housing
• Installation uses factory bolts—no special tools required beyond common hand tools

How durable and leak-resistant is the spacer in everyday use?

Constructed from anodized aluminum, the spacer resists corrosion and holds up under engine bay temperatures. The supplied O‑ring seals the mating surfaces; proper torqueing and a clean sealing surface ensure long-term leak-free performance.

• Anodized finish protects against oxidation and wear
• Precision machining gives accurate port alignment and flat sealing faces
• O‑ring included to prevent coolant leaks when installed correctly

Who is this for: The JADSOrBoBi thermostat housing spacer is aimed at engine builders, hot rod enthusiasts, and performance mechanics who need extra clearance or convenient coolant ports on Brodix HV series intakes or SBC/BBC V8 engines. It’s a practical add‑on for custom plumbing, retrofits, or when upgrading carburetor and intake components without altering original parts. Before purchase, verify intake and thermostat housing bolt patterns to ensure compatibility.
