Bolt in compliment to the Carli Low-Mount Steering Stabilizer. Adjustable from 70-200 psi to run neutral (no directional influence at 70psi) or at 200psi to counter the right-hand pull inherent to tires like Toyo Mud Terrains. This is NOT a primary stabilizer and MUST be run with either a Carli or OEM lower stabilizer in the factory location.
