ThHis has probably been beat to death but I get all kinds of different answers when I search...
I have 5100s set at 1.75 and the rear TSB... I would like about 1" more lift in the rear so it has a slight rake to the front. I carry a lot of gear very often so the rear sets a little low most of the time.
Which would be a better option... simply add a 1" block and U bolts to the rear or get the AAL for TSB which says it lifts the rear 1.5"?
Would the AAL make the ride harse?
If the 1" block is installed properly it should be safe for normal diving right? I have had 1" blocks in my Bronco for 8 years with no problems and I have wheeled it a lot.
Also... would raising the rear change the wheel alignment? I would think it would have to have some sort of impact. Maybe small but some...
