I have recieved my Truckspring Air Bags for 2003 patrol with 50mm lift inside of 6 days from USA and that was over the easter period
Great service and easy to purchase
A question to those who have purchased the same, do I use the spacer they provide (it seems to be of a smaller diameter than the coil ) as I will still need to use a larger spacer to make up the difference inside the coil length ?
Where can I purchese this spacer or what do I use to make up the spacer?
I am guessing that I may be able to get material from engineering supplies or can I purchase correct spacer from ARB or similar?
What is the approximate cost?

By the way the cost of bags landed here in Geelong $186.00

Thanks for all the info

That would be Trucksprings, in the US where he got them from, google them.

Just use the spacer supplied ,the bags work on expansion of the bag between the coils ,not on the bag length verticaly ,,you will find 10-15psi unloaded firms the ride nicely ,,go upto 35psi fully loaded and towing.

Hi Mark,

The small spacer sits at the bottom and is required to "form" the airbag such that when the spring compresses, the "spacer" pushes into the airbag and thus it folds back into itself. Not easy to explain in words but very simple to demonstrate.

Am not sure about a larger spacer to make up for the 50mm lift, but would imagine it would be the full diameter of the inside coil - not very helpful I'm sorry.

Cheers

Captain

Am I misreading these replies?
On a Nissan the spacer referred to fits on top of the airbag and into the coil spring support bracket,the hose goes though the centre of the spacer in the hole provided.
If you want to use it on a lifted suspension another spacer (not supplied by truck springs) is required under the air bag on the lower spring mount.
If the lift is moderate say no more than 50mm the bag will stretch out a bit further and you can get away with it,if the lift is more than this the bag tries to expand to reach each end support beyond its recommended elastic limits and will not last as long.
Although as stated the bags expand between the coils to change the spring rate ,they still stretch between the retaining brackets i.e the spring top and bottom mounts.
Truck springs cannot supply the spacers,you could try Polyair through their agents such as Pedders,but what I did was just buy two rubber wheels of the correct diameter and with flat sides,and used the axle hole to bolt them to the lower spring mount which has a centre hole in it.

Yep ,in one respect you are missreading the replies ,I did state that no extra spacer is required as the bags "expand" between the coils ,,, now if you have the bag totally filling the coil vertically pray tell me what happens to the bag when that coil is forced to full compression or to full extension ,,,

Hi Mark,

Just a suggestion. Get the top tower reinforced, with the lift, airbags and rough roads you'll rip the top tower.
