I know this is an old thread, but need some insight before I do this. I have concerns about total axle travel and 'bottoming' after I remove the two spacers. Are the bump stops the limiting factor on total travel, or are the shocks fully compressed(bottomed out) before the bump stops hit? I was thinking about getting shorter bump stops to regain my total axle travel, but will that kill my rear shocks (compression/bottoming failure).
Also, does the rear sink a significant amount w/ 1000 #s or more in the back? I just tow hitch haul, and no serious off-road (mostly gravel roads). I think my tongue weights are under 300 #s, depending on which trailer is hitched. Thanks for your insights in advance.
