Air Lift 99531 LoadLifter 7500 XL Ultimate Pro Series Air Spring Kit

The Air Lift 99531 LoadLifter 7500 XL Ultimate Pro Series is a heavy-duty rear air spring kit engineered for drivers who demand maximum load-leveling performance with premium hardware and professional-grade installation. Available exclusively through Air Lift's certified ProSeries installer network, this kit delivers serious towing and hauling support while restoring proper ride height and vehicle stability under the heaviest loads.

At the heart of the kit are 7-inch double-convoluted bellows air springs capable of up to 7,500 lbs. of load-leveling capacity. The oversized air spring volume — up to 20% greater than the LoadLifter 5000 series — means the springs can generate greater leveling force at lower air pressures, resulting in a smoother, more controlled ride whether you're loaded or running empty.

Key Features:

• 7,500 lb. load-leveling capacity — tackles the largest towing and hauling demands
• 7-inch double-convoluted bellows air springs — up to 20% more volume than LoadLifter 5000 for better leveling at lower pressures
• Fully adjustable air pressure: 5–100 PSI — dial in precise support for any load condition
• Internal closed-cell urethane foam jounce bumper — absorbs road shock and protects the system even at zero PSI
• Upper and lower roll plates (Air Lift exclusive) — protect air spring bellows from abrasion and increase load capacity
• 2-ply fabric-reinforced rubber construction — built for maximum strength and long service life
• Ultra-high-strength nylon composite end caps — as strong as steel, but lighter and fully corrosion-proof
• No-drill bolt-on installation — most kits utilize existing frame holes with all necessary brackets and hardware included
• Compatible with most 5th-wheel and gooseneck hitches
• Eliminates squat, trailer sway, body roll, and bottoming out for improved braking and steering control
• Maintenance-free air springs with safe zero-PSI operation
• Backed by Air Lift's limited lifetime warranty and 60-Day Ride Satisfaction Guarantee
• Made in the USA
