Installation summary

Installation of the Fall-Line Motorsports rear lower tension arm and fixed toe arm set requires advanced DIY skills and about three hours, making it best suited for experienced mechanics with access to a proper lift. You will need specialized spring perch tools to safely manage the load on the rear suspension, along with standard metric hand tools to swap the CNC-machined 6061-T6 billet arms with the factory components. The most critical step is ensuring proper torque on all fasteners while the suspension is loaded at ride height, followed immediately by a professional alignment to dial in the eccentric bolt adjustments and prevent uneven tire wear.
