Thread: Easy Lift EAS module

DJ, so you make normal height plus 30 and that makes offroad plus 30 as well ?

I'm sure it's dead on 55kph where the car lowers. Gongs start from ~43kph if I remember correctly but it doesn't lower till 55kph.

Either way it's a PITA. Love using LLAMS to keep the extra clearance at higher speeds with no lowering and no gongs.

Lowering from off-road height occurs at real speed 50 kph when the speedo is reading about 54 (2%+3kph ex factory).

Yes, should have mentioned that …. speedo indicated with 255/55/19 tyres. I've checked multiple times in both my D4s and it's 55kph indicated every time …. but let's not split hairs … .

My GOEs with 285/60/18 make the indication closer to my GPS speed. But that level of accuracy changes over the speed range.

Thanks. Peter

When in 'extended height' there is little wheel travel left in the up direction, topping out is very easily achieved which can't be good for the suspension.

If you place the vehicle into 'extended height' by dialling in +50mm with the Gap tool and selecting 'off road height' from within the cabin you have made a conscious decision to do so and so should be aware of problems and limitations when at speed of using that set up.

However, what some people don't realise (or remember) is that if you dial in +50mm at 'highway height' thinking that I'm really only at 'off road height' so all should be good but then select 'rock craw mode' then without being aware of things your vehicle will effectively enter 'extended height', perhaps without you realising it because 'off road height' is selected automatically when in rock crawl.

Normally if the vehicle enters 'extended height' there is a max speed limit of ~5kph applied. If that speed is exceeded the vehicle will drop out of 'extended height' for safety reasons (centre of gravity and suspension damage possibility) but when it enters 'extended height' by fudging things using the Gap tool then 5kph speed limitation no longer applies.

Long story short - be aware you can be in 'extended height' without being aware of it.

And extending the suspension creates a trade off in Centre of Gravity, articulation and traction .... you have to be aware of that and chose settings accordingly.
