• Direct-fit practicality with included rear blocks and mounting hardware, focused on a straightforward install that respects factory geometry and driveline angles.

Practical considerations and what to expect

Before installation, plan for a proper setup to preserve steering feel and driveline comfort. After the lift, a professional alignment is recommended to ensure optimal handling and tire wear. Depending on your exact configuration and tire choice, you may want to evaluate shock length and clearance to exhaust components, and verify there’s adequate fender and frame clearance with your chosen wheels and tires.
