BBC Water Pump Spacers - 1/2in (Pair)

The BBC Water Pump Spacers – 1/2in (Pair) from CSR Performance are precision-engineered aluminum spacers designed to relocate your big block Chevy water pump away from the engine block. These spacers address cooling system geometry issues common in high-performance and custom engine builds, allowing you to optimize radiator hose routing, accommodate larger serpentine belt systems, or create clearance for aftermarket accessories. Whether you're building a street rod, performance crate engine swap, or classic car restoration, this pair provides the correct standoff distance needed for proper water pump positioning.

Manufactured from lightweight aluminum in natural finish, these spacers deliver durability without adding unnecessary weight to your engine bay. The 1/2-inch thickness is precisely machined to maintain critical water pump bolt hole alignment while the integrated O-ring seal prevents coolant seepage at the pump-to-block interface. The pair weighs just 0.25 lbs combined, making them ideal for weight-conscious builds while the compact dimensions ensure fitment in confined engine compartments. CSR Performance's quality manufacturing ensures tight tolerances that maintain the structural integrity of your cooling system under sustained load and temperature cycling.

These spacers are essential for BBC (Big Block Chevy) engine builders working with 454, 502, or other large-displacement applications where standard pump mounting creates fitment conflicts. Installation is straightforward: position the spacers between your water pump and engine block, use the original pump bolts, and the O-ring automatically seats to create a leak-free connection. For sale as a pair, they're compatible with all BBC pump configurations that use standard bolt patterns. Proper installation ensures optimal coolant flow, prevents cavitation, and maintains the reliability your high-performance engine demands.
