Engineered specifically for 2003 through 2019 Dodge Ram 2500 and 3500 trucks equipped with 5.9L and 6.7L Cummins turbo diesel engines running dual high-pressure common-rail fuel systems, the H&S Motorsports Dual CP3 Pump Pulley (Part # 453001) provides precision belt alignment and high-RPM stability for secondary belt-driven CP3 injection pumps. When building four-digit horsepower setups that rely on twin high-pressure pumps to maintain fuel rail pressure, the auxiliary pump drive pulley must withstand harsh torsional shock loads, rapid engine deceleration, and aggressive serpentine belt tension.

Precision CNC-machined from solid billet aircraft-grade aluminum, the HSM 453001 pulley delivers low rotational mass and structural rigidity. Designed as a direct service replacement for H&S Motorsports dual high-pressure fuel kits or as a primary component for custom DIY twin-pump fabrication projects, this pulley features precision-machined micro-V serpentine ribbing that ensures proper belt tracking under full boost and heavy throttle transitions. Available in multiple durable finishes—including Raw Machined Aluminum, Black Anodized, and Red Anodized—it delivers clean engine bay aesthetics while protecting against under-hood corrosion.

Key Features & Benefits

• Precision CNC Billet Machining: Milled from solid billet aluminum to ensure concentricity, preventing pulley runout and premature belt wear.
• Low Rotational Inertia: Lightweight billet design reduces parasitic drag and relieves stress on the secondary CP3 pump drive shaft and front bearings.
• Direct Fit for HSM Dual Fuel Kits: Engineered to match H&S Motorsports Cummins dual-pump mounting bracket geometry and serpentine belt routing.
• Deep Micro-V Belt Grooves: Engineered to prevent serpentine belt slippage, rib rollover, or thrown belts during rapid high-RPM deceleration.
• Multiple Finish Options: Offered in Raw Billet Aluminum, Black Anodized, and Red Anodized to match any custom engine bay theme.
• Zero Core Charge: Sold outright as brand-new billet hardware with no core return required.

• System Notice: Designed exclusively for the top secondary belt-driven CP3 pump. Does not fit or replace the factory primary gear-driven CP3 timing gear inside the front engine gear case cover.
• Installation Tip: Thoroughly clean and degrease the secondary CP3 pump drive shaft taper and woodruff keyway prior to installation. Use a strap wrench around the pulley circumference to hold the unit firmly in place while torquing the center shaft retaining nut to manufacturer specifications, preventing marring to the billet finish.
