FAQ

We process orders when we receive them, and orders placed before 2PM will usually ship same day. If you have placed an online order for one of our “Getting Started” or “Comprehensive” kits, a Sales Technician should call you shortly after your order is placed to verify your application.  Diesel Conversion Specialists manufactures a large number of the parts included in our conversion kits, but some of the items come from outside vendors.  In some instances these items will be drop shipped directly from the manufacturer to expediate shipping if we do not have the part stocked in our warehouse.

Every state has different laws regarding emissions testing and procedures. What’s legal in Montana may not be legal in California etc.  The bottom line is this, we ALWAYS recommend that you check with your local and state offices to determine legality.

Yes. We sell a sensor adapter kit that includes adapters to help you install the stock oil pressure and temperature sensors into the Cummins engine. The stock tachometer will work with our Tach Kit, and we include the instructions to help you get the wires all reconnected to your sensors without modifying the instrument cluster or removing the dash panel. In your 6.0L and 6.4L truck you can also expect your boost gauge to work.

We have detailed instructions and technical assistance for every part we sell. If you buy a complete conversion kit (Or spend a minimum of $1500) you will receive an in depth installation manual plus technical answers to all your conversion related questions. We have done many conversions in our shop and have helped thousands of customers with their trucks.  Now you can put our proven parts, knowledge and experience into converting your truck too.
