- EZ-Flex Rear Upper Control Arm (DS/PS): Smooth operation through articulation for consistent geometry.

- Front Sway Bar Disconnects: Quick disconnects to maximize wheel travel off-road and improve articulation.
- Extended Brake Lines: Front and rear hoses provide the necessary slack for full suspension travel.
