IMPORTANT DISCLAIMER: The provided tire/wheel fitments are approximate. Actual dimensions of a given tire size can vary considerably from one brand to another. Manufacturers' wheel offset and backspacing measurement points are not always consistent. Backspacing greatly impacts tire-to-fender clearance when turning. Wheel width and backspacing influence whether the tires protrude past the fenders, and to what extent. Considering these important factors, we recommend that you fit-check your tire/wheel selection prior to purchasing.

Yes - cutting is required. Because the axle is being lowered our kit does require some cutting of the driver’s side rear lower control arm bracket. The top differential mount must be trimmed as well



No - tire wear is a definite consideration when choosing the right lift kit to purchase. The difference between lift kits is not always visually apparent but can become apparent over a period of time and use. Improper geometry of a lifted steering knuckle can result in accelerated tire wear and poor handling. SUPERLIFT knuckles are designed so that there is no additional camber or toe change throughout the suspension cycle. This ensures proper tire wear, tread life and exceptional handling.



Superlift shocks are twin tube, velocity sensitive hydraulic shocks. Bilstein shocks are a mono-tube gas pressurized shock. The Superlift shocks are coated with a white paint; the Bilstein shocks are a brushed steel body with a nickel and clear zinc finish. Bilstein shocks are more tuned for the application and offer more precise valving.
