Q: Does it fix a 2019 trail boss with factory 2” lift and a 1.5” leveling kit??? Answer this question
A: Technically the OE upper control arm is already positioned correctly on Caster for this leveled vehicle from the factory. Rancho doesn’t recommend the upper control arms to replace OE non-lifted, leveled vehicles due to ball joint position. That all said, I would not qualify it.

Q: What are people using to mount the lines to the upper control arms on 2021 gmc AT4? Answer this question
A: If you are referring to brake hoses it appears there's a threaded stud on the arm to mount the brake hose bracket. For ABS/speed sensor wires people typically use zip ties if there is no place to mount the factory clip.
