Installation and care tips

As an all-inclusive system, this lift is designed for compatibility and cohesive performance. After installation, a professional alignment is recommended to optimize steering response and tire wear. Regular inspections of the anti-wrap blocks and mounting hardware will help ensure long-term reliability. If you switch tire sizes or load configurations, reassess damping settings (particularly when equipping Vertex Reservoir shocks) to maintain the intended ride quality and control.
