🚨 6.7 POWERSTROKE OWNERS — WANT CP4 PROTECTION WITHOUT PAYING FOR A FULL DCR CONVERSION?

For the guys wanting to keep the factory CP4 but still protect themselves from a potentially expensive fuel-system failure, the SPE Disaster Prevention Kit is a great option.

Instead of replacing the CP4, this kit reroutes the fuel system so if the CP4 starts coming apart, debris is isolated instead of being sent through your injectors, rails and high-pressure fuel system.

It also gives you a way to actually monitor the health of your CP4. The return filter features a clear bowl so you can visually inspect for debris, along with a sensor that can alert you if a problem develops.

✅ Keeps the factory CP4
✅ Helps protect injectors, rails & high-pressure fuel system
✅ Clear bowl lets you monitor for CP4 debris
✅ Sensor provides warning of a potential CP4 problem
✅ Reusable return-side filter
✅ No cutting — clean, factory-style installation
✅ Reversible
✅ Much less expensive than a full DCR conversion

A DCR conversion is still the way to go if you want to eliminate the CP4 altogether, but if you’re not ready to spend that money, this gives you another level of protection and a way to keep an eye on the health of your CP4.

🚨 FORD 6.7 POWERSTROKE OWNERS — DON’T WAIT FOR YOUR CP4 TO FAIL 🚨
We’ve been seeing more CP4 failures come through the shop lately, and the damage gets expensive fast.

When a CP4 fails, it can send metal through the entire fuel system—damaging the injectors, rails, lines, and tank. A preventive DCR conversion can save you from a $10,000+ fuel-system repair.

The DCR replaces the failure-prone CP4 with a more reliable high-pressure fuel pump.

Don’t wait until your truck will not start and the fuel system is full of metal.

📞 Call or text Superior Diesel now at 405-969-3312 to schedule your DCR conversion before it’s too late.

We just finished a full front-end overhaul, trans service, and diff flush on this 3500. A truck that handles right and shifts smooth lasts longer and works harder. Whether you’re towing or daily driving, we make sure it’s done right.

Another 6.7 Powerstroke in the shop!

We’re taking care of an upper oil pan reseal to stop an oil leak and keep this truck on the road.

If your Powerstroke is leaving spots in the driveway, give us a call before it turns into a bigger repair.

This 6.0 Powerstroke came in with a no-start condition and the engine felt like it had excessive drag while cranking.

After diagnosing it, we found the A/C compressor was locked up, which was putting a heavy load on the belt system and ended up burning up the starter.

Once the belt was removed, the truck started right up.

Now we’re replacing the complete A/C system to make sure the repair is done correctly and the truck is ready for the Oklahoma heat.

A failed A/C compressor can cause more than just no cold air — it can leave you stranded.
