I am dropped 4 inches of suspension drop in the front and around 5 inches of spring drop in the back. Then wheels and tires shorter than stock and drop me another 1-1.5". If you look back through this thread I posted a picture of the front stock bumpstop at ride height. It looks really close but its a soft bump stop so it gives quite a bit. I probably have 2 inches of up travel on the front. Rear is a totally different story, I have the poly bump stops that come with the McGauhys 2/4 drop and with the 4 inch spring cut 2 coils. I bottom out on hard bumps (think like railroad tracks at speed). The poly bump stops dont have as much give as the stock foam do, so when the back bottoms out it hits hard. 99% of the time the ride is fine, but if I hit a pot hole or a shift in pavement, I hear it.
Price you pay for looking cool.
If you do a search for threads I started, there is a picture of my truck completely stock. Top of this thread is current pics.
