You repelled down the face of Longs Peak? That's awesome! I've climbed it twice, but it's been awhile. I nearly fell off the Narrows at the bottom of the home run stretch. Some yahoo slid down and bumped me pretty good. I got a REAL good look of what you repelled down. That sounds like a lot of fun to do. I haven't done that stuff in awhile, I wonder if they make harnesses that fit me? I doubt it...maybe if I look near the livery stables....

Disco303, nice job on Holy Cross trail! I've seen some photos of that trail before. That is definitely a tough trail.
Sounds like you are ready to be the first LR3 through the Rubicon. Let me know if you ever want to do that. I'll accompany you, and take some publishable photos.

I've been thru Tahoe a few times, and have always wanted to run it, just never had a rig with me. Who knows, maybe we should put something together for next season out there.

For those who are testing this out, I'm still curious if any articulation is lost by tricking the sensors to heighten, or does it still have full range of motion?

The Matzker lift, from what I understand, basically increases air pressure which limits some suspension travel. There was also a concern of weakness in the CV joint running super & super + modes for extended periods.

What makes tricking the sensors any different in these aspects, other than it can be swapped back and forth with stock?

Thanks Very Happy

The Matzker lift kit AFAIK is an on road handling fix more than an off road solution. The higher air pressure would give a harder ride and also assist in the air operated sway bar effect.
Others may know more than me.
I would think you may have problems in the super extended mode if you shorten the links too much.
I have not heard of anyone operating the super extended with the mod yet.

But isn't off-road mode now in essence close to super extended mode Caver, or am I misunderstanding (again Laughing)? I take it the jury is still out on what will happen when the rig bottoms out & raises itself then.

Available travel stays the same regardless of ride height. Hence, the 'articualtion' relationship between individual wheels is also constant. The shock is only so long and so short. The selected height just changes the point in that available spectrum where the shock comes to rest. Obviously, in standard height there is lots of available down travel but limited compression, and the exact opposite at higher settings. Lots of available compression with less droop. The overall range of travel at each corner doesn't change, only at which end of the spectrum that travel is obtainable. Granted, at the increased spring rate of higher settings, it takes more force or weight, if you will, to utilize it.

Spring rate is spring rate whether achieved through an ECU, or the link mod. In the end, It's just an increase in spring rate. And yes, I'm sure over use at those heights will wear the rest of the system prematurely.

I'm not sure that this is the case. I've certainly noticed less articulation when at extended height, which I put down to the greater pressures in the bag and hence less compliance.

I know of two incidents (I think both in the UK?) where CV's have failed in extended height, but that's not what I'd call an endemic problem. I've also done a lot of off-roading at that height (and with fairly heavy 32" MTs fitted) and haven't had a problem yet.

Cheers,

Gordon

About 47 000 km or so.

The CV failures were when the car was at extended, or super extended height, and full steering lock applied, along with power.

So in theory with this trickery, if I were to keep the height in normal mode (which is now close to off-road mode) for the most part, that should alleviate these issues and work much like it does w/o the mod when in off-road mode, only now I'm allowed to go at faster speeds & raise it to extended mode myself when needed. Cool

That sounds correct to me Tami, but you need to factor in some tire realignment also (ify ou are going to run it full time on paved roads)
