Water Pump Spacer Kit SBC 3/8in

The Water Pump Spacer Kit SBC 3/8in from ALLSTAR PERFORMANCE is a precision engineered solution for Small Block Chevy and V6 engine builders seeking optimal water circulation and belt alignment. This aluminum spacer kit addresses a common challenge in engine modifications: repositioning the water pump relative to the engine block to accommodate aftermarket timing covers, damper upgrades, or custom accessory drives. Whether you're building a street engine or race application, this 3/8-inch spacer maintains critical cooling system geometry while preserving OEM mounting interfaces.

Constructed from lightweight aluminum, the Water Pump Spacer Kit SBC 3/8in provides a rigid spacer block that sits between the water pump and engine block, maintaining proper belt tension and impeller clearance. The kit includes precision-cut gaskets that ensure a leak-free seal at both mounting surfaces, eliminating the need for aftermarket gasket materials. The 3/8-inch thickness accommodates common front-end modifications while keeping the water pump in the proper plane relative to the crankshaft damper and serpentine belt, preventing belt wander and premature wear that can result from misalignment.

Engine builders performing crank trigger conversions, installing aftermarket timing covers, or upgrading to larger harmonic balancers will find this spacer essential for maintaining cooling system integrity. The kit is compatible with standard Small Block Chevy 262, 305, 350, and 400 cubic inch engines, as well as most SBC-based V6 applications. Installation requires only basic hand tools and a torque wrench; simply remove the original water pump, install the aluminum spacer block with gaskets, and remount the pump with factory bolts. The compact 4.85 x 0.65 x 6.9-inch dimensions ensure fitment in tight engine bay configurations.
