W/P Ply Twin 6 Rib 3.5in Diameter

The W/P Ply Twin 6 Rib 3.5in Diameter water pump pulley is a precision-engineered serpentine drive component designed for Chevy and Ford vehicles requiring reliable coolant circulation. This dual-groove pulley replaces worn or damaged factory units and restores proper belt tension and power transfer to the water pump. Whether you're performing routine maintenance, rebuilding an engine, or upgrading a cooling system, this aluminum pulley ensures consistent flow rates and extends the life of your serpentine belt assembly.

Constructed from lightweight yet durable aluminum and finished in black anodized coating, the W/P Ply Twin 6 Rib 3.5in Diameter pulley features six ribs optimized for serpentine belt engagement on modern drivetrain layouts. The twin-groove design accommodates dual serpentine configurations common in high-output and fuel-injected engines, distributing load evenly and reducing slippage during peak coolant demand. The black anodized finish resists corrosion, oxidation, and thermal stress while maintaining a professional appearance under the hood. At 3.5 inches in diameter, this pulley delivers the precise gear ratio necessary for optimal water pump speed without compromising belt life or mechanical efficiency.

Engine builders, restoration shops, and DIY mechanics choose this KRC Power Steering pulley for OEM-equivalent fitment on Chevy and Ford platforms. Installation is straightforward—simply remove the old pulley using a harmonic balancer puller and seat the new unit with proper bolt torque specifications. This product ships as a single pulley and is compatible with standard serpentine belt kits; verify your vehicle's year, engine displacement, and belt configuration before ordering to ensure correct fitment. Proper installation ensures your cooling system operates at design temperature, preventing overheating and extending engine longevity.
