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.
