WILL NOT FIT LIMITED 4RUNNER MODELS WITH X-REAS HYDRAULIC STRUTS.Uneven suspension height, or “lean” is a common issue with most 4Runner pickup trucks, described as a lower static ride height on the driver side, typically 0.5" to 1" lower than the passenger side. This problem is attributed to extra vehicle components being located on the driver side of the truck. The fuel tank, battery, steering column, the driver, etc. Many owners end up going down a rabbit hole trying to find a solution, including expensive options such as larger or stiffer springs on one side to compensate for the weight distribution.Supreme Suspensions Lean Spacer is a perfect addition for your 4Runner, providing a quick and simple installation to remedy uneven ride height. Our Lean Spacer is made of High Strength Steel, laser cut through a series of computer controlled processes and powder coated in a brilliant black finish to prevent oxidation and corrosion. This spacer can be used on stock suspension and with most aftermarket leveling and lift kits.IMPORTANT:Please note that spacer thickness to lift height is NOT a 1:1 ratio.
