CNRAQR LS Water Pump Spacer Adapter Kit for Camaro LS1 to LQ4/LQ9/LSX Engines — Aluminum, Corrosion-Resistant

CNRAQR LS Water Pump Spacers are an aluminum adapter kit that lets you mount an LS1 Camaro-style water pump to a variety of Gen III/IV Chevy small-block engine blocks for cleaner intake and hose routing.

This adapter set bridges the difference between Camaro LS1 water pumps and Chevy truck/other LS-series engine blocks (LQ4, LSX, LQ9, LS6, L33, LS2 and similar 4.8L–6.0L Gen III/IV V8s). Built from corrosion-resistant aluminum, the spacers correct bolt pattern and pulley alignment so you can fit low-profile intake manifolds and tidy up coolant hose paths without repeatedly machining the housing or sourcing rare pump variants.

Will this kit fit my engine and model year?

This CNRAQR adapter was designed for broad compatibility across many LS-family engines. It supports the 1998–2002 LS1 Camaro water pump pattern and mates it to numerous Chevy Gen III/IV small-block V8s produced between roughly 1999 and 2019.

• Compatible with LS1 Camaro water pump bolt pattern.
• Mates to LQ4/LQ9, LSX, LS2, LS6, L33 and other 4.8L–6.0L Gen III/IV blocks.
• Intended for Chevy small block V8s from about 1999–2019.
• Verify your block casting and pump bolt spacing before purchase.

How does the spacer improve installation and engine layout?

The spacer centers the water pump and pulley so your belt alignment and hose runs stay correct when swapping pump types. By enabling a Camaro-style low-profile pump, you gain clearance for reduced-height intake manifolds and simpler radiator hose routing, which is useful in tight engine bays or custom builds.

• Maintains precise alignment between pump and crank pulley.
• Permits installation of low-profile intake manifolds.
• Can simplify radiator hose and accessory placements.
• Eliminates need for custom machining in many swaps.

What materials and durability can I expect from this kit?

CNRAQR manufactures the spacers from a premium aluminum alloy chosen for strength and corrosion resistance. The material withstands typical under-hood conditions, resists rusting, and keeps bolt torque points stable over time when installed correctly with proper seals and fasteners.

• High-strength aluminum alloy construction for long service life.
• Corrosion-resistant finish suited for coolant exposure.
• Machined faces to preserve pump flatness and sealing surfaces.
• Lightweight compared with steel adapters, reducing added mass.

How straightforward is the installation for a DIY mechanic?

Installation is intended to be straightforward for experienced DIYers and professional shops. The kit keeps water pump alignment accurate, so you replace the old spacer or adapter without complex fabrication; basic hand tools and attention to seal surfaces are all that’s typically required.

• Direct bolt-on design to match factory pump and block holes.
• Requires gasket/sealant and standard torque sequence for pumps.
• No special machining in most applications—verify fit first.
• Follow engine-specific torque specs and coolant refill procedure.

Who is this for: The CNRAQR LS Water Pump Spacers kit is aimed at engine swappers, hot-rodders, and garage mechanics converting between Camaro LS1 water pumps and other LS-series blocks. It’s useful for builds that need low-profile intake fitment, tidier hose routing, or a reliable adapter solution without custom machining. If you’re modifying a Gen III/IV Chevy small-block V8 and want a durable, bolt-on route to use an LS1-style pump, this kit provides a practical, corrosion-resistant option.
