TerraFirma Springs & Shocks ; Cones and shock mount -2"

[Mark_Solesbury]

Been outside in the rain sorting my suspension out today.

Ive fitted the origional TerraFirma Heavy Duty springs back that me were fitted as the new medium ones are far to soft for my liking...

It now sits pretty much 37.5 inch all round from the ground to the bottom of the wheel arch.

Ive also fitted a shock mount dropping plate, and a pair of dislocation cones.

I doesn't dislocate much, but it does. I tried it without and the spring popped out of the mount...

This is on a lump of concrete down at skew.




I also checked that the OME and the TF shocks are the same length...

Glad you got it sorted mate.
Hope it works well, dropping the mounts makes a fair bit of difference :dance:

If you fit longer shocks and shcok droppers, do you need to fit longer bump stops too :-k I reckon I do on the RRC :-.

whys that then?

RRB
The terrafirma dampers would appear to be standard length and seeing as they (the dampers specificaly) are not advertised as being any longer than standard that would make sence.


By rights you could say if the damper mounts are lowered by 2" then the bumpstops shoould be lowered to match to ensure the dampers never bottom out. In practice though because the springs are so much longer/stiffer there are a number of trucks running similar setups and the suspension doesn't comopress enough to require the bumpstops. You can draw your own conclusions about this.

I spent a lot of time measuring dampers on the RRC, because with air suspension you do hit the bump stops frequently, every time you put it into access mode in fact.

I found that standard shocks were about 2" short of bottoming out when the axle hit the bump stops and if I fitted plus 2" shocks then I still had about 3/4" travel left on the shocks, my LSE has Arnott GIII air bags BTW, never fit extra long shocks onto a standard air suspension car 8-[

SO I reckon for Blue which is lifted 2" that perhaps 2 1/2" to 3" shocks would fit ok at a push but if I fit 2" shock droppers with the  2" shocks I already have then I need to protect the shocks with at least 1" extra bump stops (I already have those somewhere too).

Though as you say the stiff springs mean the axle never sees the bump stops it is conceivable that they might and the amount of force needed to take the springs down that far would definitely ruin a shocker if that bottomed out first.

Not sure if the Defender has the same shock geometry though, or the same ride height.
