Rear air springs that mount alongside the factory leaf springs and add up to 5,000 lbs of load-leveling support for towing and hauling, with an internal jounce bumper and no drilling required.
why this one — The Ultimate version adds an internal jounce bumper over the base LoadLifter 5000, so the air spring doubles as the bump stop and the truck rides better unloaded. Honest downsides: the listed price moved between two checks this session so treat it as unconfirmed, and Air Lift own page names Sierra without stating Sierra-specific years, so confirm your exact year before ordering.
