SL-6 Slam Specialties Air Bag – 6″ Diameter, 200 PSI, Single 1/2″ Port, Fully Rebuildable

When it comes to premium air suspension components, the Slam Specialties SL-6 Air Bag is in a class of its own. Proudly designed and manufactured in the USA, this high-quality air spring offers a perfect combination of strength, precision, and long-term value. Built with 6061-T6 CNC-machined aluminum hardware and engineered for a non-ballooning design, the SL-6 ensures consistent performance at every ride height.

Whether you’re upgrading your show truck, restoring your air ride system, or building a brand-new custom suspension, the SL-6 delivers the control, durability, and rebuildability serious builders demand.

Built for Longevity – Fully Rebuildable Air Bag Design

One of the standout features of the SL-6 is its rebuildable structure. Unlike traditional air springs that require full replacement when the rubber wears out, the SL-6 allows you to replace just the bellow. This means:

• Lower maintenance cost – A bellow replacement costs less than half of a full air bag.

• Extended service life – Keep the same hardware and restore performance to like-new condition.

• Environmentally friendly – Less waste compared to discarding an entire air spring.

Whether it’s natural rubber aging over time or accidental bellow damage, your SL-6 can be restored without replacing the whole unit.

Advantages of the SL-6 Slam Specialties Air Bag

1. Superior Manufacturing Quality

Every SL-6 is designed and made in the USA, ensuring quality control from start to finish. The 6061-T6 CNC-machined aluminum port and mounting inserts resist corrosion, provide precision fitment, and eliminate the risk of stripped threads.

2. Consistent Performance with Non-Ballooning Design

Cheaper air springs expand outward (“balloon”) when inflated, leading to clearance issues and inconsistent suspension geometry. The SL-6’s non-ballooning design ensures:

• No rubbing against suspension components.

• Consistent ride height control.

• Stable handling under all loads.

3. Internal Bump Stops for Added Protection

The integrated bump stops prevent over-compression, protecting both the bellow and your suspension components. This reduces shock loads and helps maintain proper suspension geometry.

4. Versatile Fitment

The SL-6 is perfect for:

• Custom show builds – Drop your ride for the ultimate stance.

• Daily drivers – Maintain ride comfort while achieving a lowered look.

• Performance applications – Quick response for improved handling.

Installation & Compatibility

The SL-6 is adaptable to many custom suspension configurations, including:

• Custom front control arm air ride setups.

• Rear axle bag-over kits.

• Coil spring replacement systems.

• 2-link and 4-link custom builds.

If you’re upgrading or installing a complete system, we recommend pairing the SL-6 with other Gauge-Store products for maximum performance:

• Air Valves & Fittings – Precision 1/2″ NPT components for leak-free performance.

• Air Line Tubing – High-pressure rated lines built for air suspension.

• Compressors – Reliable air supply for fast lift times.
