Suspension upgrade for tug

[Nomad1946]

Hi,
We have a '92 Landcruiser, 4lt diesel, manual transmission. It has travelled 290,000 plus a tad, is regularly serviced and is in A1 Nic.
However, the "pump-up" suspension pillows are part their use-by date and hence we need to upgrade .....
Question:
Should we replace the pillows? Instal heavier duty springs? OR, a combination of sorts.

Our current van is a 2007 Jayco Poptop .. 16'. However, we will, eventually, upgrade to a bigger/heavier van .

Cheers,

[Lance]

Do you really need to drop the bundle and up grade the vehicle ?

I assume you have checked cost to replace what needs to be updated on the '79 ?
Pretty good unit from what I've read.

Hi Nomad1946.

If the bum of the car hangs down and you get a lot of pitching, that would be the best clue.
And then it depends on things we don't know. I mean how bigger a vehicle is coming,what ball weight over and above what you have etc.

Also is your truck a turbo?...And your driving tolerances.

I have a 16'6" poptop right on its load limits and its fine. I reckon going to 2.5 ton would require me to be a lot more patient, but no problem.
In a naturally aspirated vehicle I would consider it too hard work these days. I always prefer an auto to tow with as well.
In tough 4x4 work though a manual is a great vehicle.

My thinking is you don't know till you give it a go.... All depends on the head accountant.

Hi Nomad,
Wondering which Landcruiser you have is it an 80 Series and what are pump up pillows?
I thought that the Landcruiser at the time was a 4.2Ltr engine.

I noticed Lance has called it a 79 Series.

Hi JR, She's an 80 series .. 4.2L. "Pump up pillows" are "pump up " shockers.
