Does SumoSprings that Fit 2012 GMC Yukon XL Replace Factory Bumpstops  

I have a 2012 yukon xl 1500. I was wondering if it is OK to use the Sumo coil helpers in conjunction with their overload bumpstock replacements. I have a truck vault that adds some weight to the rear of the Yukon, so I thought the coil helpers would help with that, but Id also like the SumoSprings for when I tow. I just dont want to do something ill-advised. Im not a big fan of air spring assist.
