Q: How hard is the install?

Straightforward if you are already installing camber arms. The bracket bolts to the UP left rear camber arm using a fixed locating interface for repeatable positioning, you transfer the OEM sensor and linkage across, then torque everything to spec. Minimal tools required. Owners dialing in ride height with the billet height-adjustable rear spring arms usually do it all in one session, and a calibration verification afterward follows your regional service procedure.
