5,000 Pounds of Load-Leveling Support

The DEEAGLE kit provides up to 5,000 pounds of suspension load-leveling support.

Benefits include:

• Reduced rear-end squat
• Better trailer stability
• Improved braking balance
• More consistent steering
• Improved suspension control
• Reduced bottoming out

The load-leveling rating reflects suspension support only and does not increase the truck’s legal payload or towing capacity.

Adjustable Air Pressure

Air pressure can be adjusted between 5 PSI and 100 PSI depending on the load being carried.

Benefits include:

• Softer unloaded ride
• Additional support when towing
• Adjustable ride height
• Improved suspension tuning
• Better vehicle balance

Manual inflation valves are included, while onboard compressor systems can be added separately for greater convenience.

Improves Towing Performance

When towing heavy trailers, helper air springs can improve several aspects of vehicle handling.

The DEEAGLE system helps reduce:

Rear Suspension Sag

Maintains a more level ride when carrying tongue weight.

Bottoming Out

Additional spring support helps prevent suspension compression over bumps.

Trailer Sway

A level truck provides improved trailer stability and handling.

Body Roll

Additional spring rate reduces excessive lean while cornering.

Headlight Aim

Keeping the rear suspension level helps maintain proper nighttime visibility.

Installation

Unlike many newer bolt-on air spring systems, this kit requires drilling during installation.

The manufacturer includes:

• Installation instructions
• Labeled hardware
• Mounting brackets

Owners with fabrication or suspension experience may find installation manageable, while professional installation is recommended for those unfamiliar with suspension modifications.

Construction

According to the manufacturer, the kit is designed for long-term durability using:

• Heavy-duty rubber air springs
• Steel mounting brackets
• Adjustable air fittings
• Reinforced hardware

Routine inspections of air lines and fittings can help ensure reliable long-term performance.

Final Verdict

The DEEAGLE Air Bags Suspension Kit (DESK57215) offers an affordable suspension upgrade for owners of older Ford, Dodge, and GMC trucks that regularly tow or haul heavy loads. Its 5,000-pound load-leveling capacity, adjustable air pressure, and broad vehicle compatibility make it a versatile solution for restoring suspension confidence to classic pickups.
