🚨 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.
