Built to Last: The Bullet Proof Diesel Water Pump for Cummins Engines
When it comes to diesel performance, reliability isn’t a luxury, it's a necessity. Owners of Dodge and Ram trucks powered by the legendary Cummins 5.9L and 6.7L engines know that keeping their cooling system in top condition is key to long-term durability.
At Bullet Proof Diesel, we don’t just replace weak factory parts, we engineer long-term solutions. The Bullet Proof Diesel Water Pump for Cummins engines was designed to eliminate common failure points found in OEM pumps and deliver unmatched performance and longevity.
In this blog post, we’ll break down why upgrading your water pump matters, what makes BulletProof 5.9L & 6.7L Cummins Water Pump, and how it’s built to handle anything you throw at it on the road, off-road, or on the job.
Why Upgrade?
Factory water pumps have several weaknesses that can lead to premature failure and costly downtime. Many OEM designs rely on plastic impellers and small bearings, which wear out quickly under high loads and extreme heat. Over time, that can mean overheating, coolant leaks, or even engine damage.
Bullet Proof Diesel engineered a solution that’s built to thrive under pressure. Every component was upgraded with precision materials and smart design to ensure the pump not only performs better but lasts significantly longer.
Upgraded Features

- Larger Bearing: Robust roller and ball bearing assembly ensures smoother operation and extended lifespan.
- Metal Impeller: Replaces the OEM plastic version to resist cracking and flexing under heavy loads.
- Precision Machined Aluminum Housing: Precision-machined for strength and longevity.
- Aluminum Drive Pulley: Lightweight design featuring cooling fan action to help dissipate heat and minimize parasitic loss.
- Top-Grade Seal: Designed to prevent leaks and withstand extreme conditions.
The enhanced bearing assembly features a robust roller and ball bearing system, engineered for exceptionally smoother operation and greater load-carrying capacity. This sophisticated design not only extends the unit's lifespan but also significantly elevates its reliability.
Metal Impeller
Unlike factory plastic impellers that can crack, flex, or warp under stress, Bullet Proof Diesel’s metal impeller ensures consistent coolant flow and long-term durability.
Precision-Machined Aluminum Housing
Each pump is crafted from CNC-machined aluminum for maximum strength, corrosion resistance, and precision fitment. It’s designed to withstand high temperatures and harsh conditions.
Aluminum Drive Pulley
The lightweight aluminum pulley reduces parasitic loss and features built-in cooling fan action to help dissipate heat more efficiently.
Top-Grade Seal
High-quality seals protect against leaks and maintain reliable performance, even under extreme temperature fluctuations.
Every component of this pump was purpose-built to eliminate the weaknesses found in OEM designs and to deliver the durability that diesel owners expect from Bullet Proof Diesel.
