Shocks to Suit Parabolic Spring Upgrade

Parabolics will likely raise the vehicle a little but if you still have your check straps in place then the standard length shocks should do the job. You have to be careful with longer shocks as they lose out on the compressed length so don't necessarily help unless you also move the upper mounting point. Parabolics being a softer spring should compress easier than standard and will therefore cause an issue. The Rocky Mountain ones that were on my Game when I bought it were matched with ProComp dampers and they are still on there.

I'm not a big fan of parabolics having had both Rocky Mountain and two sets of BritPart ones sag pretty badly. I ended up taking a set of aftermarket standard springs and diamond cutting and chamfering the ends as well as removing two leaves from the back and one from the front. These seem to work pretty well and are much less choppy on the SWB than original standard springs.

I forgot to mention that.. I was told that with standard springs, landy's don't really need the shocks. As one won't notice any handling differences, with or without the shocks. With paras it's a must.

By set them up properly I mean removing just enough leaves to make them softer while still able to carry the load you want, cleaning and oiling them to make them slide over each other better, chamfering the top of each end of the leaf to help it slide over the one above and cutting the ends to a diamond shape for the same reason. Keep them clean and oiled after doing all that and they will work surprisingly well.

And yes with a standard spring pack with a bit of rust and dirt there is probably enough friction to make shocks a bit redundant. If they are working properly you will need shocks.

Hey Wolf, don't buy overseas mate - they have an Aussie distributor!
Ben at "Landy bits"
Ill post his contact details if you like.

Check out this post of mine here Wolfie. I did what Isuzu Rover advised and earlier on in the thread are shots of the unbelievable articulation he gets from his modified leaf springs.

Thanks Ashhhhh,

Too late, I have already ordered them, plus a few other bits and pieces..

Post the details, they will come in handy..

Use range rover rear on rear and SWB rear on front. Or full set of procomp extended travel which are always available through Victorian parts provider (can't say who here)

Gas filling a damper does NOT increase damping rates.
All it does, depending on damper design, is reduce or eliminate cavitation, and most people never get a damper hot enough or piston speeds fast enough to cause this in normal, day to day driving.

Personally, I'd use Koni's.
