What are the differents between them? I need to level ip mostly the rear of the track and also plus 200 lb extra in the bed permanently
Don't quote me on this but from what I've heard regarding Gen 2... Eibach is better on the street and geiser is better offroad.
Geiser is only offering a 2.5" front and a slightly heavier duty 1.5" rear
Eibach will have a level front spring, a lift front spring, a rear lift spring and an HD rear spring.
Kind of pick your poison. I personally am gonna go with geiser once his rears come out. I prefer to support a small business in the offroad community and I've never heard anyone complain about them personally.
