Saggy rear end

We were out with another delica last weekend and noticed that our rear was saggy we did have about 350lbs hanging off the hitch and camping gear for 5 in the back and he only had his own gear in the van, but none the less the sag was significant.
Would just doing HD springs help us out or do we need shocks ect? Can springs be done at home on the delica or is this a shop job (I have seen them done on other lighter vehicles without special tools but I assume that these heavy springs would be difficult to pry into position)?
Should I consider air bags or just go straight to new springs? Where can i get these components i have found the blue hd springs on c.c.a.'s web site but have read only ok reviews on these particular springs.
If someone is able to explain the rear suspension to me in a simple way that would also be helpful as a clear understanding of how the componets work together would be nice.

The CCA rear coils are great, just installed them for my 2"
lifted L400 gasser.

Air bags are the only solution if you want to stay at stock height. Either Firestone bags online or Lordco brands.
rear coil Installation requires floor jacks, stands,wood blocks and wheel blocks, solid floor to work on and of course large sockets and tools.
good luck

Can these springs be installed on a stock height vehicle without further mods or no?

the CCA springs will raise the back end of your delica approx 2".
Air bags will maintain the height and stiffen the rear coils.
Try Dobinson springs in Australia for new stock springs.

Shocks, sway bar links, brake lines ect. Will these springs lift the rear of the van or no?

brake lines okay but the load sensing proportioning valve needs a 2"block, shocks need measured to see if they fit (best to change them too), SB links need a 2" block. Blocks require longer bolts too.
PM me, you can stop by and see the mods needed.

What would the ride be like in the front? or are you re indexing torsion bars ?

Compare the ride to another delica. it's not a simple answer. reindex and try it for a while.

Does anyone know the part number for Firestone bags to fit a swb L400?

I just recently installed the CCA HD coils and cranked up my torsion bars without any other 'lift' in the front and she's sitting pretty.
Definitely cured the saggy rear end and then some!

Croftcastles,
Did you do anything else to the rear suspension along with the springs? Shocks, links, sway Bar?
Thanks

I did replace all the sway bar links and bushings with OEM. Still have the stock shocks and sway bar though.
We're going to have a constant heavy load (camperized) so once we're fully loaded (50% there), I imagine it'll level out where the stock sway bar and links are sitting where they should.. in the meanwhile it's swaying less I suppose.
If you wanted to use the stock sway bar and links, you can and just add a 1 or 2" block between your frame and the links. There's tons of pictures online and it looks very simple.
Only concern at that point is new shocks.. in that sense I'd say keep the stock ones until they need replacing! Mine still feel fine and it's been 6 weeks.

Update on my rig.. rear end is sagging once again (Could be the camper conversion

) Anyhow, the CCA HD coils worked great with a gutted van. But started to sag as soon as weight was added. Now bottoming out over every speed bump and pot hole. Ordered in airbags to the rescue.

Could be you're reaching capacity of the entire suspension and drive train. Usually I weigh my rig when I travel at after hours gov't truck scales. Note the F & R weights for future reference.
Unless there's heavier coils available air bags are the only solution.
Buy bags as long and wide as possible to fit the entire space inside the coils. That'll spread the load out over the entire coil area.
Michigan Truck (US) has firestone bags and all the sizes available for around $A100.
