Disco suspension lift

Hi guys, I want to swap my 2" HD lift for a 3" HD lift in the near future, 2 reasons, firstly, the bearmach +2" HD lift that's fitted now only lifted the truck 30mm so now the 35's rub on the arches and secondly, the shocks are shot! I already have HD spring retainers, -2" turrets and dislocation cones ready to fit so I don't want a kit that comes with all that. Can anyone recomend some decent +3" HD shocks and springs? I also need +6" stainless brake hoses.

Thanks in advance

If you go above 2" then you would do well to go with +5" shocks with +2" turrets to gain extra articulation.

I got my hoses (150mm) from Foundry 4x4. Service good and they have an eBay shop.

Who made your shocks, Pro Comp?

Yeah, they're not too great

Greenhornet, surely you get more articulation from +3" shocks and -2" turrets, as this is a combined 5", as where +5" shocks and +2" turrets only gives a combined 3".

I was just thinking the same.... im sure he meant -2 turrets..

In my mind +5” shocks and +2” turrets will give two inch greater travel up the way and three inch more travel down the way while +3" shocks and -2" turrets will give 5” further travel down the way but you will loose an inch up the way.

Of course where the neutral point will be in all of this depends on the springs.

I have no experience at all of suspension lifts I am just doing the maths.

assuming you have all the other bits to achieve maximum articulation, like cranked trailing arms, etc.. :

if you have a turret at 0" (standard) and a +5" shock then, your axle will travel 5" down... and will stop as the shock won't go any further.. but will be flapping about

if you get a -2" turret, then your shock will still travel those 5" inch, but means that you'll have more pressure applied to the surface you are on...

does that make sense? to be honest im getting confused now!

Ok guys it is very confusing and I spent a lot of time talking to Gwynn Lewis on this subject as I though that a shorter turret would be better.

However the springs are a limiting factor a mentioned above. I have plus 3" springs which move the neutral point down 3" ergo giving the suspension lift.

With standard shocks and turrets you immediately loose articulation in the downward plane and only maintain standard articulation in the upward plane.

Now by adding minus 2" turrets you will gain articulation in the downward plane but loose in the upward plane.

With me so far? I'm not lol

So by adding plus 2" turrets you gain in the upward but loose in the downward so you add extreme length shocks, minimum 5" and now you have both the lift and the articulation up and down.

That's right, but I want to increase the lift so that I can fit bigger bump stops to stop the tyres catching on the arches. So I'd be no better off.

Think I'm goin for terrafirma TF123 and TF124 shocks with -2" turrets and +3" springs.

The articulation kit is the 5" shocks with +2" turrets as stated, but for disco owners who don't always have arch room, often you're looking to simply move the whole system downwards.

Bearmach do a monster rear spring for disco, and use a 2" rear bearmach on the front to compliment the 3" rear. Afaik
