maXpeedingrods Triple Bellow Air Spring is a heavy-duty, universal air suspension bag rated for up to 2,600 lbs per spring with a 1/2" NPT air port and a 250 mm design height.

Designed for buses, trucks, trailers, mini trucks and light-duty vehicles, this triple-bellow air spring from maXpeedingrods replaces or upgrades traditional coil or leaf suspensions to give better load support, reduced vibration, and adjustable ride height. Built from durable materials and engineered with a rugged top plate and standard mounting hole pattern, it fits a wide range of applications where reliable air-assisted suspension is required.

How does this air spring improve load capacity and stability?

The triple-bellow geometry increases air volume and distributes pressure across multiple convolutions, allowing the spring to support heavier loads while maintaining ride compliance. Because each spring is rated to 2,600 lbs, you can add air pressure to tailor firmness and stability depending on cargo or towing needs.

• 2600 lb load capacity per air spring for heavy loads and towing
• Triple-bellow design for increased air volume and even force distribution
• Adjustable air pressure to tune firmness and balance vehicle stance
• Reduced squat and improved control when hauling or towing

What are the key specifications and how will they fit my vehicle?

This air spring uses a 1/2-14 NPT single air port and common mounting hole sizes to simplify installation on many chassis and subframe conversions. The top plate diameter and bolt pattern match standard retrofit kits, and the 250 mm (9.8") design height gives a practical operating range for both lifted and OEM-height suspensions.

• Air port: 1/2-14 NPT single port compatible with standard fittings
• Mounting holes: 3/8-16 UNC — aligns with common brackets and plates
• Design height: 250 mm / 9.8" for versatile ride height adjustment

How durable and maintenance-friendly is the maXpeedingrods air spring?

Manufactured from robust rubber compounds and reinforced materials, this air spring resists abrasion, ozone and road debris to extend service life. Routine inspection of fittings and mounting hardware is straightforward, and the use of standard thread sizes makes replacement parts and fittings easy to source.

• Standard NPT and UNC threads for easy sourcing of fittings and hardware
• Triple-bellow construction reduces stress on a single rubber fold
• Minimal maintenance: periodic leak checks and mounting bolt inspections

Can I install these air springs myself and what accessories are needed?

Many mechanically inclined owners can complete the installation with basic tools, a compatible bracket kit, and common air-suspension fittings. For safe and reliable performance, follow torque specs for the 3/8-16 UNC fasteners and use proper air-line connections to the 1/2" NPT port.

• Requires compatible top and bottom brackets for secure mounting
• Use 1/2" NPT fittings and appropriate air lines for inflation
• Standard 3/8-16 UNC hardware secures plates to brackets or subframes
• Professional alignment and safety check recommended after fitment
