A: The geometry is similar but everything else is different, the brackets and arms are not made from the same material as the DOR long arms. This particular product you are asking the question on is just for replacement arms for people who already have the old Cepek brackets, pre-2012. If you don't have the original Cepek long arms, you need to look at our part number 1087. That is the full long arm box kit using similar materials as the older Dick Cepek long arm kits. All the info you need about lift height is on that product page.
