This complete kit is built and designed for the 2WD Frontier Pickup. Featured in our system are our signature plate style upper control arms which allow for factory alignment after the lift is installed. Also included in the kit are CALMINI heavy duty torsion bars and our add-a-leaf system to help smooth out the ride and increase payload capacity. The complete suspension system also includes Vecton control arm bushings, sleeves, new ball joints, laser cut precision bent shackles and hardware, rear sway bar links, bump stop extensions, CALMINI performance shocks, complete hardware, and installation instructions. The best setup to pre-run your Frontier or tackle off-road trails.
