Years ago I emailed KBEE three times and asked a US distributor to help. They declined. And their normal springs were WAY too soft to be useful. And I concluded if the spring choices were limited that their shock body would be also too wussy.
One SS parts distributor and I got into it big time on the OS when he started proposing KBEE REAR lifting coilover shocks to be mounted to the SHOCK mounting brackets of our platform. As if the shock brackets could accept the force we slam onto the axle tubes using the normal spring perches. I declared the shock brackets to be a totally unacceptable place to apply constant spring force PLUS the dynamic force of shock activity PLUS the abuse we give them offroading. Compared to his normal customers, who steer carefully around those scary 2" speed bumps, our needs were different and he continued to push the product. Nothing came of it.
You can actually get 1" of lift out of those units if you crank the adjuster up:

But you could buy them and install stiffer springs, and then see if the shock travel is good enough.
