BUILT FOR THE ROAD LESS STABLE

Progressive rear suspension support that engages when terrain — or gear demands it.

WE KNOW WHAt your rig goes through

Rear Squat

  • Kills stance

Washboard Bounce

  • Rear-End Oscillation

Roll & Load Shift

  • Top Heavy Instability

Airbag Hassle

  • Intensive & Leak

Mechanical stability for uneven terrain

  • Reduces body roll            
  • Control rear sway       
  • Stabilize uneven loads
  • Smooths washboard bounce
  • Maintain unloaded comfort
  • 100% Fit-And-Forget

Stability matters more than ride height

AIRBAG SYSTEM

  • Air pressure dependent
  • Requires manual adjustment
  • Airlines & fittings
  • Potential leaks
  • May require onboard compressor
  • Requires constant upkeep
  • Can feel stiff if over-inflated
  • Can Cost $2k+ for full setup

Based on typical air spring systems.

ADDING LEAF SPRINGS

  • Increases static spring rate
  • Always stiff — even unloaded
  • Can reduce ride comfort
  • Fixed rate support only
  • Does not reduce bounce isolation
  • Little-not impact on sway and body roll

Traditional fixed-rate upgrade.

Built to support NOT REstrict Spring Travel

  • Original design concept was for secondary & off-road                  
  • Works with factory spring travel
  • Maintains off-road articulation
  • Engages progressively under force

Frequently Asked Questions

Yes, RoadActive Suspension does typically raise the rear unloaded ride height by .5''- 1.5''. The exact amount will vary based on the vehicle, condition of the leaf springs, the kit part number and most importantly the tension set on the spring upon initial install.

Yes. RoadActive Suspension is a fully mechanical system with no air lines, compressors, hydraulics, or electronics.

That simplicity makes it extremely reliable for remote travel where durability and low maintenance are critical.

No. RoadActive Suspension works with your factory leaf springs and does not limit suspension travel.

The progressive spring design allows the suspension to move naturally while adding support when load or force increases, making it well suited for trucks that see both highway driving and off-road terrain. See a real world example HERE

Yes. Overlanding setups often add significant weight from roof tents, recovery gear, water, fuel, and storage systems.

RoadActive Suspension reinforces your factory leaf springs to help maintain proper suspension support under this added weight. This helps reduce rear sag, improve vehicle balance, and maintain better handling both on and off the road.

No. The system uses a progressive mechanical spring, meaning it increases support only when needed.

When driving unloaded or over smaller terrain changes, the suspension remains compliant while still helping control bounce and body movement.

Yes. RoadActive Suspension is compatible with most lift kits, upgraded shocks, and off-road suspension setups.

It installs directly onto the rear leaf springs and works alongside other suspension upgrades.

No. One of the biggest advantages of RoadActive Suspension is that it requires no adjustments.

There is no air pressure to manage, no compressors, and nothing to monitor. The system automatically adapts as load and suspension forces increase.
