Hey all,

I have a 1998 HZJ75RP cruiser ute with heavy duty custom leaf springs in the rear which for 4wding are way to stiff and aren't being used...

The reason they aren't being used is because I now have a 2009 V8 Turbo Diesel cruiser ute which is currently the work vehicle for now...

My issue: because I have a 4 heavy and always full toolboxes on the back of the new V8 cruiser the rear is sagging a fair bit and that was the same when I first got the 75 cruiser ute, thus I bought the Heavy Duty spring pack.

So to get to the point, I want to know if it is possible to swap the rear stock springs from the V8 cruiser ute with the H/D rear springs in my 75 cruiser ute?

Since the V8 cruiser ute has a longer wheel base I then assume the leaf spring is longer?

Any and all advice/help is appreciated.

Cheers,
George

Just get a tape measure and run it around the spring from eye to eye They should be around the same.
Longer wheel base doesnt necessarily meen longer leaf springs it may be just a different chassis.

As Get Outmore says - you can't swap them. The 79series springs are heaps longer.

bugger...

in that case, can the 79 springs be put onto my 75 since it'll be softer and make the rear a bit higher?

or would it just throw everything off?

thanks otherwise for the help so far

No they are a different length. The 79 series leaf springs are the longest of any landcruiser.
Even if they did fit the shackle angle would be horrendous.

What about seeing a spring expert and having a couple of leafs added to the 79 series springs and having the springs re-set to give you some added height. This is what I anticipate doing with mine.

Have you considered airbags? With them your vehicle maintains its original comfortable ride but you now have the ability to adjust your cruiser back to level as the loads alter in weight. 5 years ago I put them [firestone] on my HJ61 trayback conversion and the ride is very comfortable , empty or loaded fully with the usual camping paraphenalia [200litres of water, 350 litres of diesel, plus huge kilos of sundry tarps ,tables, poles, etc,etc] and the weight of a caravan on the tow ball.
Serendipity of Mandurah put airbags on his 2008 V8 turbo diesel ute that carries his Travelander camper with ease.

the standard springs on those 79s are pretty crap and really dont take a load well. there almost like ther sagged from the start.

when the standard springs crap out and get replaced of our work vehicles its alot easier to clean them underneath due to better clearances

The mining companies dont even give the 79 series springs the benefit of the doubt. They replace them before they leave Perth to save having to do them 3 months later at the mine.
They go straight in the scrap metal bin along with the shockies
