110 Expedition Suspension mods
Hi,

I have a 110 utility prepped for over landing, I currently have the Terrafirma Bigbore dampers with standard ride height and standard springs with the helper spring on the rear inside the main spring. Standard anti roll bars fitted.
I’m looking to reduce body roll when fully laden with a roof rack. I do not what to compromise the ride when empty. I have been looking at doubling up on the Terrafirma Bigbore’s on the rear, I was wandering if there is a kit to fit these; secondly stiffer anti roll bars or the X-end anti deflex roll bar, has anybody else done a similar modification what are your thougths???

Forgive me if I'm speaking out of turn but, I have a 110 with a heavy duty Brownchurch rack on which is covered with chequer plate, I have overloaded the thing often in the course of my now discontinued business(35 sheets of 11mm osb isn't the lightest thing to put up there Whistle ) If I were looking to travel distances "loaded up" I would look at where I would be putting the heavy items, the roof rack hasn't got a never worry about weight capacity, off the top of my head it's a 150kg max limit. I added the helper springs inside the rear coils and have no arb's, ok I have some body roll with the roof rack loaded around 150kg but not what I would call unacceptable.
I would look more to loading with more thought to weight distribution and save your money to further your trip.

Unfortunately you can't really have the best of both worlds. It is working out the best compromise.

Twin Big-bore shocks with Standard springs will be a mistake.... You will find it is over dampened which will make the suspension jar more. When doing shorter corners the springs on the outside will compress less, but on longer corners i will compress to the same height as before the shocks..... bit will take longer to stabilise after.

The only way to prevent it from 'swaying is either

A. Stiffer springs
B. Stronger ARBs.

The problem with the above thought will directly impact when you are unladen.

Other option would be to install airbags inside the rear springs (instead of the helper springs). You can then put air in them when loaded and let it out when unloaded.

Also to consider.... What roof rack have you got?

Defender gutter is rated to a maximum of 150Kg (including the rack). The average rack is about 40ish Kg so you can only add another 100Kg. If you then have a roof-tent you have about 50Kg to spare (a couple of jerry cans).

As JWL has mentioned try and re-distribute your items or maybe get a trailer.

I agree with JWL. I would look at your loading situation. If you only have minimal weight up there at the moment, Roof tent, couple of Jerrycans and some camping wood then i would have a look at your suspension. On my exped prepped 90 i have Koni Heavy Track Raid Dampers and Eibach progressive springs with no Anti Roll Bar and it handles perfectly. On my roof i have 2 large spacecases (light stuff, sleeping bags etc) a couple of jerrycans and some wood.

As Glyn said airbags are really good if you only have the vehicle loaded some of the time as they allow for a softer ride when you are empty and a good ride when you are full.
