SIERRA | FLOW FORMED | SIMULATED (17-20”)

The Sierra is offered in a 17x9 or a 20x9! The wheel is made by Flow Formed Aluminum Construction. After it has been casted, Flow Forming Technology applies pressure to the inner barrel of the wheel, while spinning. This process stretches and compresses the aluminum, which increases tensile strength by optimizing grain structure of the aluminum.  The Sierra is available in a wide variety of bolt patterns and two offset options. Choose 4.50" backspace (-13mm Offset) to push the wheel further out and 5" backspace (0mm Offset) to bring the wheel closer into the steering knuckle. By having this higher offset wheel, your steering scrub radius will result in better performance and longevity of components. We also enlarged the lug nut bore for better lug nut options and clearance. If unsure, please email or call with questions regarding backspace and bolt patterns. The Sierra offers you the option to run a true off-road beadlock clamping ring for race/extreme vehicle use or a "simulated" acc
