This engineered kit transforms your 1971-1976 Chevelle, El Camino, or Monte Carlo from a vintage cruiser into a modern-handling machine capable of accommodating massive wheels and tires. The Level 2 kit goes beyond basic clearance by incorporating adjustable suspension components that dramatically improve cornering, stability, and overall driving dynamics.\u003c\/p\u003e \u003cp class=\"ds-markdown-paragraph\"\u003eThe core of this system is the complete front and rear wheel tub set, which provides the necessary clearance for wheels up to 315mm wide, allowing you to run modern rubber for unprecedented grip. Unlike simple tub kits, QA1’s Level 2 package includes their legendary adjustable front coilover shocks and rear shocks, giving you precise control over ride height, damping, and spring rate. This means you’re not just adding space for bigger wheels—you’re fundamentally upgrading the car’s suspension architecture to handle the increased footprint.
