The Melling K-20J Oil Pump Rebuild Kit is a high-performance solution for rebuilding and upgrading the oil pump on engines that require increased oil volume, such as those found in 400, 430, and 455 cubic inch applications. This kit, manufactured by the respected automotive aftermarket brand Melling, offers an excellent balance between durability, efficiency, and flow capacity.

The Melling K-20J Oil Pump Rebuild Kit includes all necessary components to rebuild an existing oil pump or install a new one. The kit contains a high-volume, billet aluminum oil pump housing, a set of precision machined gears, an O-ring set, and a gasket kit. These components are made from top-quality materials, ensuring reliable and long-lasting operation.

The billet aluminum housing in this kit provides a robust foundation for the oil pump's operation. This material offers superior strength and heat dissipation, ensuring that the oil pump can handle the increased demands of high-performance engines. The housing is also designed with a smooth, polished finish that not only looks great but also minimizes turbulence within the oil flow, reducing the potential for unwanted wear and tear.

The precision-machined gears in the Melling K-20J Oil Pump Rebuild Kit are critical components for efficient oil flow. These gears are made from high-strength materials, ensuring they can withstand the rigors of high-performance applications. The gears are also designed to minimize tooth contact, reducing wear and noise, while maximizing oil flow.

The O-ring set and gasket kit included in the Melling K-20J Oil Pump Rebuild Kit ensure a proper seal between all components. These seals are made from high-quality elastomer materials that can withstand the extreme pressures and temperatures encountered in high-performance engines. The gasket kit includes all necessary gaskets for a successful installation.

The Melling K-20J Oil Pump Rebuild Kit is a must-have for engine builders, racers, and enthusiasts who demand the highest level of performance from their engines. By upgrading to this high-volume oil pump, you can ensure that your engine remains well-lubricated, even under the most demanding conditions. The kit's ease of installation, combined with its robust design and superior components, makes it an excellent choice for those seeking to maximize their engine's potential.

While it comes with a higher upfront cost, the potential performance gains and longer engine life can make it a cost-effective solution in the long run. However, it requires some mechanical skill to install and may not be necessary for all applications. Ultimately, careful consideration of your engine's specific needs and your mechanical abilities is essential before making a purchase.

If you're looking to maximize the performance of your engine or have a high-mileage application, the Melling K-20J high-volume oil pump rebuild kit is an excellent investment.
