I finally installed the new, one-size-fits-all, Eibach 2.5 spring kit and 34x10.5x17 BFG KO2’s. The change in ride height is substantial. The front end level is very noticeable (with winch). While I only have 40 -50 miles under my belt, I believe the ride is slightly improved. Strangely, the cabin noise level also seems lower. But I don’t have an explanation as to why.
I decided against 35’s as I watched YouTuber Ronny Dahl show his 35’s rubbing against the wheel well at full articulation. Honestly, it was a small compromise. I feel that I’m good-to-go for the trails I like to run. The most immediate difference is the ride height and entering / exiting the vehicle. I’m 6’2 and I’m about at my limit for throwing a leg up to climb in. I may have to install a bolt-on step for around town driving.

This looks very good in my opinion! Actually I think it looks better than the 35“ solution, as they appear to me slightly to big.

Nice looking rig. I also run the Eibach 2 1/2 inch lift with 285/70R17 KM3’s and get no rub whatsoever.

Sorry for my ignorance and laziness in looking but do they have a 1.5 lift as well?

There is a 1.7 inch lift. It used to a 1.2 when I backordered mine originally, But before the backorder was filled they released the 2.5 inch and I went with that.

Hi bikesandguitar and Cheshire Cat, Ok gotta weigh in. First off, thanks for the measurement after the lift. The lift looks great and love the Queens Red.
As Cheshire Cat noted below, yes I have collected detailed measurements of different Grenadier heights from many forum members including Cheshire Cat for a special project, soon to be unveiled in about 2-4 weeks. To all of those forum members who provided me detailed photos and height measurements, many thanks in advance.

No issues with front drive line vibration offroad or at speed with the 2.5" lift? Thanks

I am not exaggerating. I like the ride better with the lift. It takes a few miles for the springs to sit right thru the curves. After that, it moves like a big cat. I have no issues. Steering is tight. Doesn’t wander or vibrate.

Is this using stock shocks? I would be interested in fuel mileage once you get some miles on it.

Looks great

I just installed the 2.5" Eibach springs over this past weekend. I agree with the above, the ride is better with the new springs. It is noticeably stiffer but handles and rides better. Steering is improved as well. I have not yet changed the tires. I will move up to 34s, but still researching it. Of note, I haven't found anyone besides the dealer who has the Grenadier alignment software in their system, so I will have to take it back to the dealership 200+ miles away to get the alignment checked. It doesn't seem to need alignment as it drives straight even at 90 mph, but I have always checked alignment after a lift.

For anyone planning to do it yourself, a few tips. It should go without saying, but you do need a lift and jack stands. The front brake calipers will have to be taken off to get enough movement in the brake lines. The rear ones you can get enough play with loosening the line attachments to the axle. Control arms, sway bar linkages, shocks in the front and rear need to be disconnected, the drag link in the front needs to be disconnected as well. With this the axle will drop enough to get the springs out and easily put the new ones in. We needed a little extra movement in the front control arms to get them reconnected so we used the alignment adjustments to do so. We marked them ahead of time so we could adjust them back to the pre-disassembly position. We did not need to do this in the rear. One more note that might not be self explanatory, to orient the springs correctly, the writing on them should be right side up. I hope this helps as I have not seen any posting on this as a DYI.

Yes, stock shocks. I may upgrade in the future. I haven’t clocked mileage but have not noticed a significant difference.
