Sorry to have to say this about another company you tried, but the young kids over at 4 wheel parts are also clueless about Raptors. Daystar is the same idea as ReadyLift in how they use blocks on top, rather than underneath, like a Perch kit. I asked 4WP about their experience with Deavers, and they recommended 4” blocks under my Raptor factory leafs “to maintain the ability to tow”. I laughed and walked out the door, never to return.
Dallas has one of the best Raptor shops in the country, so I recommend stopping by Texas Motorworx and getting ideas from them. They can do mild to wild, so do not be intimidated by their website pictures. They will gladly tell you what you can do within your stated budget of $2K. (Your options will be limited, but they can walk you through the choices)
