    JEGS Easy Kits are designed by JEGS high performance racing professionals to help you get all the performance parts you need for your race car, hot rod or truck.

    Upgrade your engine’s cooling system with the Moroso Electric Water Pump — a high-flow, lightweight solution designed for performance builds across street, strip, and racing applications. Unlike belt-driven units, this auto electric water pump eliminates accessory-drive drag to free up horsepower and reduce parasitic loss.

    Built from billet or machined aluminum, this unit features a premium electric motor with sealed ball bearings, heavy-duty windings, and a stainless shaft for long life and trouble-free operation. It draws a modest 7–10 amps (depending on model), helping protect your battery and charging system under extreme conditions.

    Flow performance is impressive: the pump can push more coolant than most mechanical units—up to 21% more in some configurations—and maintains excellent circulation at idle and under high loads. That means better temperature control, reduced risk of overheating, and stronger reliability during demanding use.

    If you’ve been hunting for a robust moroso electric water pump solution, this product stands out for its race-worthy build quality, direct-mount fit to stock water-pump locations (for many applications), and its ability to simplify your cooling system by removing belts and brackets.

    In summary: choose the Moroso Electric Water Pump when you want maximum cooling efficiency, lower mechanical drag, and a premium build that supports high-output engines. Install with confidence and let your engine run cooler and stronger from start-up to redline.
