Built for Strength and Longevity

The AU-7 Slam Specialties Air Bag is engineered with premium-grade materials to withstand years of use under the toughest conditions. The heavy-duty rubber bellows are reinforced to handle high PSI levels without ballooning, ensuring consistent performance at any height.

The steel 3/8-16 mounting inserts provide rock-solid attachment points, reducing flex and preventing premature wear. With its precision-machined 1/2″ NPT port, air delivery is smooth and unrestricted, giving you faster lift and drop speeds compared to smaller port bags.

Why Choose Slam Specialties AU Series?

The AU Series is designed to be a direct replacement for traditional air springs while adding Slam Specialties’ engineering upgrades for better performance, longer life, and improved ride quality.

The AU-7 is ideal for:

• Custom trucks seeking a perfect balance between stance and drivability

• Hot rods and classic cars needing adjustable ride height without sacrificing comfort

• Heavy-duty builds requiring high PSI handling and stability

• Show vehicles looking for ultra-low stance with quick lift capability

Non-Ballooning Design

One of Slam Specialties’ signature features is the non-ballooning design. Unlike cheaper air springs that expand outward when inflated, the AU-7 maintains its shape, ensuring consistent ride height geometry and preventing interference with nearby suspension components.

This not only improves safety but also maximizes clearance inside your wheel wells—critical for lowered and tight-fit builds.

Perfect for Air Suspension Conversions

If you’re building a full custom air suspension system or upgrading your existing setup, the AU-7 is a plug-and-play solution for many common mounting patterns. With 2.8″ minimum height, you can achieve a near frame-laying stance, while 11.5″ maximum height ensures enough lift for speed bumps, trailer loading, or rough roads.

Installation & Compatibility

The AU-7 Slam Specialties Air Bag is sold individually and designed for universal use in custom air suspension setups. While it can fit a wide range of applications, always measure your existing setup to ensure proper fitment.

If you’re pairing your AU-7 with other Gauge-Store components, here are some recommended upgrades:

• Air Management Kits – For complete control over ride height and air delivery.

• Air Line & Fittings – High-quality fittings to match the 1/2" NPT port.

• Air Tanks – Store compressed air for faster lift and multiple height changes.

• Compressors – Powerful air compressors to keep your system at optimal PSI.

Durability Meets Serviceability

While the AU-7 is built to last, Slam Specialties also focuses on ease of service. Should the rubber bellow ever wear out or become damaged, it can be replaced without buying a whole new bag—saving you time and money in the long run.

This makes the AU Series a cost-effective choice for serious enthusiasts who demand the best without overspending on full replacements.
