This aFe CONTROL Rear Leveling Kit is made from 304 stainless steel and provides a 1.625-Inch lift in the rear to provide better off-road performance. Self-Leveling Rear Air Suspension equipped Toyota Tundra models are lowered in the rear to match the front level. This kit is designed to replace the level sensor bracket on air suspension equipped models, prompting the truck to raise the rear to the same height as coil spring trucks. Combined with the aFe CONTROL Front Leveling Kit (PN: 416-72T005-R), your truck will remain level at a lifted height from stock. Installation of these leveling brackets can be done at home with the proper tools and safety precautions. Installing these brackets does not require any disassembly of the air suspension.
