Another F-250 getting the FULL treatment here at Superior Diesel Performance! 💪🇺🇸

This truck came in for a complete engine reseal, a thorough once-over from front to back, a fresh set of cab mounts, and an S&S DCR fuel pump conversion! 🔧

We're tackling those common oil leak points, checking everything over, and replacing the worn cab mounts to restore ride quality and eliminate unnecessary vibrations.

We’re also upgraded the factory CP4 fuel pump to the S&S DCR pump, helping protect the fuel system from a potential catastrophic CP4 failure that could lead to thousands of dollars in repairs!

Our goal is simple: Fix it right the first time, improve reliability, and keep these trucks on the road for years to come! 🇺🇸

Disaster Prevention Kit Installed!

One of the smartest preventive upgrades you can make to your 6.7 Powerstroke!

The factory CP4 high-pressure fuel pump is known for potentially failing and sending metal contamination throughout the entire fuel system, damaging injectors, fuel rails, lines, and other expensive components.

The Disaster Prevention Kit is designed to help contain that metal contamination if the CP4 fails, potentially saving you from a fuel system repair costing thousands of dollars!

⚠️ Keep in mind: This kit does not prevent the CP4 pump itself from failing. It helps protect the rest of your fuel system from the damage a failure can cause.

2019 F-350 6.7 Powerstroke came through Superior Diesel Performance for some much-needed preventive upgrades to help improve fuel mileage, performance, and long-term reliability!

We also installed a Banks Cold Air Intake to improve airflow and help this Powerstroke breathe a little easier!

Our goal is simple: Better efficiency, stronger reliability, and keeping these trucks on the road where they belong! 🔧🔥

Another full F-250 reseal underway!

Oil leaks on these trucks usually don’t get better with time. What starts as a small seep can turn into a much bigger mess, covering the engine and transmission, damaging rubber components, and making it harder to spot future problems.

A full reseal lets us address the common leak points all at once and get the engine sealed back up properly for better long-term reliability and peace of mind.
