If you haul heavy cargo or tow regularly, you've probably looked into suspension upgrades to help with sag and sway. Two popular solutions—SuperSprings® and airbags—offer extra support but in very different ways.
How SuperSprings and Airbags Work
SuperSprings mount above your existing leaf springs and activate automatically as the load increases. They use a dual-roller shackle system that applies support only when needed—light loads leave them mostly inactive, while heavy loads cause full engagement for added stability. No compressors, no adjustments, and no maintenance required.
Airbags, on the other hand, sit between the axle and frame. They rely on compressed air to lift the rear end and support extra weight. You’ll need to inflate or deflate them depending on the load. Many systems require compressors, airlines, and manual input. They’re effective, but they demand regular checks for leaks, pressure levels, and wear.

Key Comparisons
-
Support Style: SuperSprings use mechanical force; airbags use compressed air.
-
Adjustability: SuperSprings adjust automatically; airbags require manual inflation.
-
Installation: SuperSprings are typically bolt-on; airbags often need extra hardware and lines.
-
Maintenance: SuperSprings are maintenance-free; airbags need routine attention.
-
Durability: SuperSprings use steel and composite parts; airbags use rubber that can wear out.
-
Ride Quality: SuperSprings preserve your factory ride when unloaded; airbags can stiffen the ride if overinflated.
-
Cost: SuperSprings are a one-time investment; airbags may come with added costs for compressors and repairs.
Why Choose SuperSprings
SuperSprings are ideal if you want:
-
A low-maintenance solution with no air leaks or pressure checks
-
Support that increases automatically as you add weight
-
Long-lasting construction with no rubber parts
-
A clean, simple install without drilling or wiring
-
One-time cost and peace of mind
If you're looking for reliable support without the extra hassle, SuperSprings are a great fit.
When Airbags Make Sense
Airbags might be a better choice if you need fine-tuned control, like:
-
Adjusting ride stiffness based on varying cargo
-
Lowering the rear end for hitching
-
Managing uneven loads in custom setups
Just keep in mind the tradeoffs—more maintenance, a more complex install, and higher long-term costs.
Bottom Line
Most truck owners will find that SuperSprings deliver the right combination of support, durability, and simplicity. If you prefer a solution that works quietly in the background without constant attention, SuperSprings are the better pick.
