Many folk use bump stops to limit body contact...
But they're just too lazy to cut, trim or hammer. I'll think.
The only reason IMO to increase bump stop height
is so that the leaf springs cannot invert negatively
And if/when they do bottom out... it's a bit softer
^ (Timbren bumps bring 'da squishy)
For those lifting more then 3" worth of suspension
It could become more critical, as more arch would be
put into those springs... and inverting those too far
could be a real problem if they broke from inverting too far.
compressing to flat is OK IMO... and I've been doing that for years
'course... you may need to have yer leaf springs re-arched
every 5-6 years... depending on how hard you are on them.
I've always maintained the oem bumps at the rear on muh '00
For up to 3" of susp. lift... they should keep the spring from inverting.
but some trimming will be the order of the day
* to get even more travel out the back...
longer shocks (10" SB's) would offer a little more droop to the axle.
But would require shock mount relocation.
I haven't done that. ...yet
so I want every bit of up travel (compression) I can have
Here's where that little bit of extra axle droop
by extending the shock lengths, could be helpful
Here's a pic of my spring... pushing it's luck a Lil' bit
but so far... it just wears them out quicker. Meh... consumable shit
example of what yer stock junk
wished it could do
