Airbag Man coil-insert air helper kit for the rear coils of the Toyota LandCruiser 80 Series and 300 Series. Choose the standard kit (CR5049) for towing and touring loads, or the high pressure kit (CR5049HP) with internal bump stop for heavy constant loads.
Airbag Man helper kits use coil-insert air springs that sit inside the existing coils – add air when the load goes on to bring the vehicle back level, then let it out and the standard springs carry on exactly as before. Because each side inflates independently, you can also correct for an off-centre load like a slide-on or water tank.
They shine when the load keeps changing – a van on the towball some weekends, a loaded tray on others. Worth being clear about what they don't do: helper airbags don't increase your GVM or payload; they manage ride height and stability within the vehicle's existing ratings. If the vehicle is always loaded, upgraded springs (with airbags for the variation on top) is the better setup.

The air springs sit inside the existing rear coils, so the factory springs stay in place. Air lines run to two inflation valves, usually mounted at the rear bar, so each side adjusts on its own. Run 5 psi unloaded and add pressure to bring the vehicle back to level when towing or loaded, up to 30 psi on the standard kit or 60 psi on the HP kit. Airbag Man notes that drilling and cutting are required for this fitment, so allow extra workshop time. Typical fitting time is 120 minutes.

Figures from Airbag Man product data. Helper kits assist the springs and do not change the vehicle's GVM or towing capacity.
These suit the following applications: Toyota LandCruiser 80 Series; Toyota LandCruiser 300 Series. Check your build date and variant against the fitment table on this page – if you're not certain, contact us with your rego or VIN details and we'll confirm fitment before you order.
No – this is the most common misconception about helper kits. Airbags manage ride height and stability within the vehicle’s existing ratings; they don’t change what it’s legally allowed to carry. We’ve written up the details in our guide: do airbags increase GVM or payload?
None at rest. This is a helper kit, not a lift kit. It stops the rear sagging under load: add air to restore factory ride height when towing or loaded, then drop the pressure for unloaded driving.
2 x Airbag Man in-coil air helper springs, mounting hardware, air line tubing, fittings, 2 x inflation valves and step-by-step fitting instructions. HP kits add high-pressure sleeves and end protectors.
The standard kit runs 5 psi - 30 psi. The HP kit adds a high-pressure sleeve over the air spring and runs 5 psi - 60 psi, for constant heavy loads or regular towing near the vehicle's limits. Both carry the same fitment and the same lifetime air spring warranty.
No. The kit includes inflation valves, so you can set pressure at a servo or with a portable 12V compressor. An onboard air control kit only adds in-cab adjustment.
