bumpstop installs

I have stock bumpstops with the original Frankenllift, so Rancho struts and OME or Rancho coils up front, I forget which, but they aren't HD. I take off my swaybar and use those bumpstops all the time, you can see the zerk mark on them from my JBA arms. I have yet the need to replace either coils or struts, so I'm just wondering if I'm lucky or what? Could it be that maybe even when the bumpstop is being hit that this still isn't compressed enough to bottom out my strut?

Lots of opinions on this – so my 2 cents.

Why longer front bump stops:
1. Keep wheels from rubbing -- (you know if you need this).
2. Prevent over compression and premature failure of springs -- (If you use coil spacers this will be a problem – add bumpstops, Spring lifts are not as apt to be a problem IMO).
3. Prevent bottoming out (full compression) and premature failure of strut -- (stock or equivalent struts WITHOUT spacers over the top spring/strut assembly, should not bottom out with std bumpstops, the geometry has not changed) (however see #2 above). Add top spacers and they may/will bottom, add bumpstops.
4. Keep Gen5 control arms from hitting top of the frame opening (you can see this).
5. Please add additional.

As you evaluate the needs for extended bump stops you can deduce that the length of extension will depend on the geometry changes – SO a general rule simplifies the decision-making.
