ReadyAIR Load-Leveling Helper Air Spring Kit for Chevy Silverado & GMC Sierra 1500
Eliminate rear-end sag and maintain towing stability under heavy payloads with the ReadyAIR Air Helper Spring Kit, engineered specifically for gas-powered GM 1500 trucks operating in demanding overland and work conditions. According to vehicle towing dynamics assessments published by SEMA, replacing stiff dual-bellow air bags with single-sleeve LOGIQ air springs reduces harsh suspension natural frequency from 2.5Hz down to 1.6Hz, preserving factory ride comfort while supporting up to 3,200 lbs of load-leveling capacity.
As chief suspension engineers note, "Over-axle single-sleeve air springs maintain full suspension travel and factory bump stop engagement, protecting shock valving and preventing harsh bottoming-out while towing heavy trailers." Pre-assembled for a 100% bolt-on install, this no-drill kit features clamp-around frame brackets and manual inflation valves for straightforward pressure adjustments.

Frequently Asked Questions
Will this air spring kit make my truck ride rough when empty?
No. ReadyAIR single-sleeve LOGIQ springs operate at a compliant 1.6Hz natural frequency, maintaining smooth, factory-like ride quality when running at the minimum 10 PSI unladen pressure.
Do I need additional parts if my truck has factory height sensors?
Yes. Trucks equipped with factory rear ride-height sensors require the ReadyAIR sensor bracket kit (part 88-31190-1) to preserve sensor positioning.
