Our Work: Off-Road

Retrofits, DPF cleaning, & maintenance

Off-Road

 

Diesel Emissions Service handles emissions retrofits, parts, servicing, and engine repair for your Off-Road construction diesel vehicles. Off-Road vehicles also require regular DPF filter cleaning and maintenance. Your Off-Road diesel requires regular servicing and may need an emission retrofit to meet CARB & EPA emissions requirements.

Off-Road regulations can be difficult to navigate. Typically, compliance dates for federal standards vary by engine horsepower, but on the state level, they can vary by fleet size, too. Standards can also depend on the type of engine, usage rates, and more. Check out our CARB page for detailed info on regulations. With over 18,000 emissions systems and parts sold or installed, DES is your go-to expert in DPF filter cleaning & retrofitting. Here are just a few examples of our Off-Road retrofits.
