I wouldn't have thought so. Unless you've got particularly stiff springs, on full compression the shocks will bottom out and likely break something off. Darren

Depends on the stroke length of the shock as they vary so much between brands. You can fit and measure to see if shock is being compressed too much on full compression of axle. Basically if the shock stops before you hit the bump stops - you won’t want to fit as they’ll soon become damaged and fail.
If yes, and you still want to fit them, then you can go for +2 shock mounts front and rear. |

Depends on the whole set up and not just the shock, I used to run a Gwyn Lewis challenge suspension kit with +5 old man emu shocks and didn’t have any issues, even when at full articulation. Gwyn also runs standard height on one of his own defenders. This does include the +2” turrets on the front and pin to pin shock mounts on the rear and extended bump stops

Yes you can as long as they either don't bottom out or you don't drive so they bottom out!
Steve's points above says it all ref bump stops +2 Don't t forget springs could dislocate if off road with longer shocks. All depends on shock really Cheers James 110 XS Utility 130 Puma Station wagon/camper (in the making) 90 Puma Hardtop |

Does anyone know the "standard bump stop" minimum shock length eye to pin, and pin to pin for front and rear?
I've also got a set of +2" shocks, and am attempting to work this out before I find it out with the vehicle immobilised for a while.....! Collapsed length of the shocks I have seems to be 14.3". I'm hoping the lengths of the "bottomed out axle" are longer than that. |

Looking on fox's website, the standard Fox 2 Pro shocks are as follows;
Ext length Col length Travel 985-24-079(R) 21.13" 13.25" 7.88" 985-24-078(F) 21.65" 13.05" 8.60" Fox Pro 2" lift shocks are as follows 985-24-144(R). 24.03" 14.95" 9.08" 985-24-143(F) 23.88" 14.30" 9.58" For the fronts, the collapsed length is 1.25" ( 32mm ) higher than standard and the rear is 1.7" (44.5mm) higher. Based on this, an extension of the bump stops by those amounts or, to be safe, an amount beyond those, will stop the shock being compressed beyond it's limit. That’s what I worked out, but I’m no suspension guru! |

Guru enough for me Paul lol.
For my setup I think I'm now concluded on needing +2" height turrets on the front but no other changes as a result of those measurements. Rears I'm headed towards ARB droppers, dislocation cones, spring retainers and some +25mm bump stops, though theres a chance I won't need the cones and retainers if the springs I pick out are long enough, but fairly slim chance. The whole thing front and rear can sit on some +1" ish springs and make it level up. Should be ok then. Wasn't quite my intention to ever go this far but the remote Res shocks are so pretty........  |

After chatting with you, I went and bought a set too
Still not decided on how to set it up just yet, larger bump stops will stop the bottoming out effect, but I like the idea of extended front turrets as that allows the shock to be sat at it's true length and not with a constant decompression state at all times if that makes sense? Extend the rear mounts too though? I've not found a system to accommodate this as with the OS it sits very close to the fuel filter and fuel pipes to the tank, but nothing stopping getting a bracket made....but then you need to remember that shocks don't travel on a linear basis which throws up some more thoughts. Dislocation cones are a given, however the figures aren't that huge in difference of travel...they're under 2" according to the figures for both their shocks and would this create a problem at full articulation? Travel difference for the front is 1.2" and the rear is just under an 1"...as long as you stop the springs compressing the shock beyond it's travel limits and damaging it, is there really an issue at the other end of the scale with such small differences in travel? |

Awesome! Great aren't they?!
For the fronts... The shock body is (I lined them up next to the other ones I have) 40mm longer than a "standard height" fox shock. Thus if you go for 40mm minimum higher turrets, you're back to a standard compressed shock length again. Gwyn Lewis does +2" turrets so 50.8mm, so you'd effectively have a 10mm shorter body length of the shock. Ideal. Perfectly safe. If you do that, from laying them side by side, and assuming we fit Gwyn +2" turrets, the shock will then droop approx 30mm further than the standard height fox. If we therefore have a spring whose free height is approx 30mm longer than land rover fitted as standard.... All good. So that's my next challenge. Figure out front spring length I have and what I want so it's min 30mm free length longer than standard. Then that's all that's needed at the front. Rear.... Same issue as you say. But I can't see how you could raise the shock higher as it'd hit the body. I was thinking that was why manufacturers only do -2" (droop increase) rear shock mounts. As +2" doesn't look like it fits to me. Side by side with the standard height again.... The body is 40mm longer. That's gotta be taken up in a longer bump stop. But I can't find a +40mm bump stop. Only +25mm. I assume that's enough because of the angle of the shock. +25mm bump stop covers you for 40mm shock length ish because of the 30 ish degree shock angle. Side by side the droop is then 70mm longer than standard fox (different to front as none taken up in the turret change). So realistically... 70mm longer spring unlikely. So it's then dislocation cones, spring retainers to add to the bump stops. Final thing is the rear roll bar. I can't tell, but with 70mm extra droop the consensus seems to be the bar needs spacing down. So I think we need roll bar downward spacers too. These were the pictures I drew.... Currently missing standard shock measurements which would complete the picture. I've only checked Vs fox standard height. Sorry rubbish quality... The drawings assume the shock eyes are lined up.

As you may have guessed I also saw those +2” Fox shox for sale. Really really good price. As I have some new Alive comfort springs to go on I thought yippee! But I asked Prolinx and Gwynn Lewis and it seems as you guys have discussed a major redesign to get them on at standard height. So simple solution is new +2” springs. But as that is not what I want I’ve passed on these and will go std height fox. No remote res though....
By the way I think these sexy Fox remote res shox come under the term Farkles. It’s something I recently came across on a motorbike forum. Farkle (n): A modification to a motorcycle that satisfies the following criteria: creates “bling,” serves a purpose (the usefulness of which is in the eyes of the farkler) and is most likely expensive. Often used among touring riders to denote or convey status amongst their peers. Ex: “I picked up a new farkle for my ST today: a GPS-based burger joint locator!” (v): To farkle; to accessorize one’s motorcycle with farkles. Ex: “Boy, John really farkled out his K1300GT; it’s even got a cup holder!” Do you see the parallel with us Landy chaps,,,,  |

Good term. I think it fits the bill nicely. 
You'd be ok at the front with them with only changing the turret. But at the rear with -1 springs, by the time you've fitted longer bump stops to cope with the extra shock body length you'll have very little upward travel left for actual suspension action. So I'm with you, at -1" height this isn't a great plan sadly. |

I've heard of Farkles before or poser as it was known long ago
Then again my truck is bright green so I guess I can't go with the excuse I'm not in it to be discreet |

Yeah sorry not the best worded post in the world lol
Tell you what though, i'm seriously tired of postage costs on stuff. I've just tried to order 4 x shock boots from Prolinx. Nigh on £12!!!!!!! Come on guys this stuff fits in a padded envelope and it doesn't need to arrive tomorrow morning via some form of premium fedex service. It's put me off purchasing. I'll get over it and do it anyway at some point as you can't buy them cheaper elsewhere, just a small rant!!
