Hello there!

I've just bougth som GB springs parabolics for my 1978' 109" soft top and the ride heigth at the back is just HIGH! I think it might have gained 8-10 centimetres (3-4") and the shocks are fully extended. I've removed one of the four layers in each spring but it doesn't seem to do much difference.

The front looks all right!

Regards Niels

I keep seeing S3 109's with parabolics which have pushed the vehicle up drastically at the rear. There's clearly a problem with low axle weight versus the strength of the springs. The shockers will be rendered useless if fully extended and render any advantages in ride from the parabolics. I personally just replace with std springs and shocks. That's the way LR designed the vehicle. Particularly if you are using the landy for fairly std use on the road. Have you tried ballasting the rear with a hefty load or heavy trailer to try to temper the springs?

I'm quite sure if the weight on the rear axle is increased with a couple of hundred kilos it will settle in. Well, but anyways it seems a bit foolish to put extra weight on the car just to bring it back down. Some of the increased ride height is of course due to the springs being three layer instead of 11 so maybe some metal plate spacers between the axle and springs could work.

It's generally recommended to change the dampers for ones with greater movement anyway.

Partly because of the general lift paras give but also because they'll articulate further both ways

PS it's normal practice to slacken everything off a little, chuck a load in and take it for a little bounce before torquing everything up when fitting any leaf springs.

You will find setting figures in the workshop manual. Sometime a ratchet strap axle to chassis is required to pull em in to place before tightening things up. As said speak to GB they will help you.
