Airbags

This collection holds BOSS air bags on their own: replacement bellows for an existing kit, or air springs for a custom build. The model number identifies the bag:

• 2400, 2401, 2403, 2500 and 2503: general replacement bags. Match the model number on your old bag.
• 2600: double bellow
• 2603: triple bellow air bags. The extra convolution gives more travel, which helps on lifted vehicles.
• 4500: 4,500 lb bellows for heavier vehicles and trailers

Bags come two ways. Bare means the air bag only. Complete kits add the parts needed to fit them. Check each listing for what's included.

BOSS bags are made from natural rubber, high-tensile steel and ballistic woven reinforcement. If you're replacing a bag in an existing BOSS kit, match the model number printed on your old bag.

Building something custom? Measure the space you have between the frame and the axle at ride height, then contact us and we'll help you pick a bag before you order.

Looking for a ready-to-fit kit for your vehicle? Shop load assist kits or universal kits. To fill the bags on the road, add a compressor.

Common questions

What's the difference between double and triple bellow bags?
A triple bellow bag has one more convolution, so it extends further. Choose triple bellow when the vehicle has a suspension lift or needs more travel.

What does "bare" mean?
The air bag only, without brackets or air line. Use it to replace a bag in a kit you already have.

Which bag fits my kit?
Match the model number on your current bag, or contact us with your vehicle details.
