In every AccuAir e-Level kit, you will get height sensors, linkage, and hardware. The linkage component of this kit can become damaged or broken from overextending or road debris leaving you with a malfunctioning air suspension system. AccuAir has you covered with a direct replacement ROT-120 linkage and hardware kit. This kit features the same components found in your e-Level kit to allow you to easily replace your damaged components with high-quality replacements. This kit comes with (1) linkage and (1) hardware kit. This kit does not include the ride height sensor. This will need to be purchased separately or within our ROT-120 ride height sensor w/ linkage & hardware kit.
