leaf springs 1ton vrs standard springs hq van

[wbute]

I run them in the back of my WB ute. They do make it ride a bit harder but as to ride height I did not do a ride height measurement before and after. However I dont notice it is too high. However it was way too low with the crap stock springs! What were they for, it wasnt handling and they didnt carry a load thats for sure.
It makes it sit flatter in the corners which is what I was after.
After playing with dirt bike suspension for years I can say for sure that two different springs the same length will not perform the same. And as you cant slip down to Eibach and buy real springs you are limited to what you can achieve with leaf springs.
If you just want to lift it in the rear and dont want any handling improvement as well just get the stock springs re-set.

My ute back in the 80's had air shockers and 1 inch thick conveyor belt (from North West WA) in the back, ride and handling was pretty good, I am no expert driver though.

I found it in the HZ features manual.

Ute or van was available with options F72, XW5 or FE7 which all got you cab-chassis rear springs.

F72 was called "Gross Load Equipment" or "Gross Load Package". Not sure what this means exactly, I thought it may mean something like a slide on camper but it also appears to be available on sedans, wagons and statesmans (except you got heavier rear coils on these). Possibly it still means any vehicle application where a permanent gross load was to be fitted?

XW5 was the "Outback Equipment Package" another special vehicle package like BO6, XU3, XX7, XU4, B47 or XY7. This package included F72 amongst other bits like mud flaps and heavy duty aircleaner (this was the only instance of factory fitted mudflaps).

FE7 was "front and rear heavy duty suspension". In addition to the tonner leafs this got you V8 tonner front springs as well.


HX looks similar except all V8 commercials got the same front springs. Not sure about HQ and HJ as yet. WB should be the same as HZ.

my yellow hz had 6 leaf springs plus a helper spring with about a 40mm lowering block i find this rides ok and sits about the right height at the rear there are plenty of pictures of this van on the forum I will find a picture and edit latter RB.sence this picture was taken I also lifted the front by about 30mm because I could see the spoiler was not going to last

Byron, I'd say F72 was more a towing package.... caravans, horse floats etc... Caravaning holidays were becoming more popular and affordable for the average family during the 70's.

After doing more reading today I came to the same conclusion. Strange name though!
