Whether you are towing or general driving you will find many benefits by fitting either Polyair Leaf Springs or Polyair Coil Springs. Airbags are designed to level the vehicle to the originally designed height up to 500kg of the load.

Tips for Polyair Coil Springs
Polyair Red Series System 1,000lbs/450kg of load support. Most bags can be fitted between the lowest coil opening when the suspension is fully extended. Additional clearance between the coil may be obtained by removing lower shock absorber mountings and lowering suspension 30-50mm. The bag should be a reasonably snug fit in the coil, however, tolerance of + 6mm is common.
Observe tension on brake hose, DO NOT STRAIN. Ensure that exhaust tail pipe is 60mm from Polyair Bag. If necessary loosen clamps and rotate or move to obtain additional clearance.
General Maintenance Tips
After fitting kits and / or extension leads inflate air bags to 175 KPa / 25 lbs and test for air leaks by applying a liquid soapy solution to all valve cores, fittings and connections.
CAUTION: Do not inflate air springs while vehicle is on frame hoist. Vehicle must be standing on its wheels before bags are the inflated.
Tips for Polyair Leaf Springs
Polyair Bellows System – 5,000lbs/2,200kg of load support and a correctly attached chassis bracket has no stress on the attaching screws.
Stands or Jacks should be placed under differential housing so that dimensional relationship between vehicle chassis and leaf springs remains unaffected.
Kits are to be fitted not more than 40mm and not less than 20mm in front of or behind the differential’s housing and usually fitting instructions specify the correct location.
Clearance from any obstructions should be a MINIMUM of 20mm (exhaust pipes 60mm at all times).
