Heavy Truck DPF Repair Service

The Best DPF Repair Service in Tennessee & Mississippi

What is DPF?
DPF (diesel particulate filter) treats your truck's exhaust by trapping particulate matter which is basically soot and ash. Diesel particulate filters have been a crucial part of a truck's emissions system. DPF's capture approximately 90% of diesel particles and soot preventing them from being released through the exhaust system.

Benefits of a clean DPF include:

  • Improved vehicle performance
  • Increased fuel economy
  • Experience fewer regenerations
  • Lover maintenance costs
  • Extended DPF life

Cleaning

The DPF must be cleaned every 150,000 to 300,000 miles to remove the built up ash. The filter should also be cleaned if a fuel injector or turbo problem causes contamination with engine oil or non-combusted diesel. This contamination cause unwanted back pressure. Cleaning methods include air blasting, de-ionized water and a vacuum-like system. This must be done very carefully to avoid any damage to the filter. The particulate matter that is removed must be handled with extreme caution to ensure there is no exposure to the very fine contaminants.

DPF and Preventative Maintenance

The DPF is yet another component that must be tracked and maintained on a heavy duty truck. Ensuring regular preventative maintenance is performed on the DPF will do wonders in ensuring the long life of the DPF. Replacing air filters and fuel filters regularly along with using the correct type of oil for the engine will help prevent any unnecessary wear and potential damage with the DPF.

I was sent because I thought something was wrong with my trailer, but it turned out that my fuse popped out in my truck. The receptionist is a blast we laughed the entire time. Thank again for the help on my trailer and the laughs with the receptionist 🤗😂🤣.

These people took such great care of me. This is my 1st box truck but they had no problem going over the truck with a fine tooth comb or explaining different aspects and functions of the truck. The pricing was affordable as well. They have definitely won my business!!!Thanks guys!!!

Called the shop spoke to John. Explained to him how my driver was at Love's Truck stop near by. He couldn't move because the diesel pump was cracked Love's kept trying to send me to Freightliner. Glad i came across Specialized truck repair in Google. John got my truck towed to his shop for a reasonable prices. They got the part for me from freightliner and got it in the truck in half a day. Price was very reasonable and since they own the tow truck I got a good price on that. I highly recommend this shop If you are a OTR driver and are looking for a shop that won't take advantage of you.

Went in for an oil change, found out that the oil pan was cracked and also there was damage to other parts of the car and so it turned out to be a very expensive repair. Took some extra time but was able to get all the needed parts in and car is now working great. Friendly service and quality job.

We had our truck towed from the dealership.  We saved moneycoming here, even including the tow bill.  We also didn't have to wait 2 weeks like the dealership said it would take.
