ProSeries LoadLifter 5000 Now Available for the 2025 Toyota 4Runner

2/10/2026

The 2025 Toyota 4Runner is built for adventure, but towing, hauling, and fully loading your rig can quickly push the limits of factory suspension. That’s where Air Lift’s ProSeries LoadLifter 5000 comes in.

Designed exclusively for professional installation, the ProSeries LoadLifter 5000 delivers proven load-leveling performance with added peace of mind for drivers who want the job done right the first time.

Built for Drivers Who Tow, Haul, and Explore with Confidence

Whether you’re towing a trailer, hauling gear, or loading your 4Runner for long trips, added weight can lead to rear-end squat, reduced control, and driver fatigue. The ProSeries LoadLifter 5000 works alongside your 4Runner’s factory suspension to restore proper ride height and stability under load.

With up to 5,000 lbs. of load-leveling capacity*, this system helps maintain balanced handling, consistent braking, and proper headlight aim without sacrificing ride quality when unloaded.

What Makes ProSeries Different?

ProSeries isn’t just another LoadLifter kit, it’s a professional-grade program designed specifically for installers and customers who want expert setup and long-term confidence.

Unlike DIY kits sold through eCommerce, ProSeries products are only available through Authorized Installers and Upfitters. That means:

For many 4Runner owners, ProSeries is the right choice when towing or hauling becomes a regular part of life and precision matters.

Proven LoadLifter Performance, Installer-Exclusive Confidence

At its core, the ProSeries LoadLifter 5000 uses Air Lift’s trusted double-bellow air spring design, reinforced with roll plates and high-strength end caps for durability under real-world use.

Air pressure is adjustable from 5–100 PSI, allowing drivers to fine-tune support based on load conditions, whether carrying weekend gear or towing heavier equipment.

The result is a suspension system that adapts as your load changes, keeping your 4Runner level, stable, and predictable on the road.

Designed for Professional Installation

The ProSeries LoadLifter 5000 for the 2025 Toyota 4Runner is engineered with installation efficiency in mind. Kits are designed to bolt on using existing mounting points, with no frame drilling required on most applications.

By pairing a premium product with professional installation, ProSeries helps ensure consistent results, from ride quality to long-term reliability.

This approach not only benefits drivers, but also supports installers by reducing install time, eliminating online price competition, and delivering a better customer experience.

Confidence Backed by Air Lift Support

Every ProSeries LoadLifter 5000 kit is backed by Air Lift’s Limited Lifetime Warranty and 60-Day Ride Satisfaction Guarantee, giving drivers added confidence in their investment.

As an added benefit, ProSeries includes installer-focused support programs designed to protect both the customer and the shop, reinforcing why ProSeries is built for professional installation from start to finish.
