    Been there done that, glad we have two vehicles and the wife doesn't work so I can park the VX and research parts when it breaks.

    Well, not to get this thread TOO much "back on topic" - I jacked up my VX today and cut my bump stops with my Sawzall. Nuthin' to it, really - I didn't even have the the rear end "hanging", and still had no problem accessing the stops. Took the wheels off, of course. Some backline: My VX is pretty much stone stock, including the original shocks (which seem to be working fine, and with no leaks), stock size wheels and tires, no lift - 72K miles, never off-roaded, etc. My stops were within 1/2" to 3/4" of the top of the axle, and showed CLEAR evidence of hitting. Afterwards, I did my usual "test ride" - I would say that the extra travel DID produce a smoother ride, though it was most evident on larger dips/bumps - the kind that caused the ENTIRE axle to move at the same time. Cornering was not effected in the LEAST; nor did I expect it to - keeping a vehicle "flat" during corners is by and large the job(s) of the front and rear sway bars, respectively. I can see no "downside" to this mod; frankly, I'm at a loss as to why Isuzu oriented the bump stops SO close to the axle on a vehicle of this type, ESPECIALLY considering its short wheelbase and predisposition to a rough ride. Makes me wonder if the original design of the bump stops intentionally ALLOWED for this mod - the second "loop" of the figure 8 almost LOOKS like the stop was designed to possibly be "relieved" if necessary/desired...

    Good thought, I would go a step further and say that I wonder if it is because all the Zus have that same rear bump stops (at least as far as the rodeos and troopers,Iwould assume the axiom as well?) Why reinvent new parts?

    That was my first thought too...

    Isuzu is well known for sourcing parts from other models.
    The VX, with an orig sticker price of $30k-+, I doubt they were gonna spend any time re-engineering new bumps for a model with a known production run of less than 6000.

    As per u$ual corporate...slap something on it & send it to the masses...
