    rear bump stops

    anybody ever replace your rear bump stops with the energy suspension part number 9.9104r?
    the stock bump stops are two bolt mounting and the e.s. stops are one bolt in the middle.
    just wondered what was involved in making the switch.
    thanx

    It was closer to the top of the list when I searched, so you can add lazy too...

    Didn't look the part number you posted but I am guessing you mean this:


    After a few hits over a couple years the metal plate started to deform a bit causing a crack in the poly - using a 1x3 steel tube spacer rather than the OEM bump stop backing piece would work better long term. They work great with oversize tires but big offset mixed with big tires need more of a spacer to keep the tire off the cladding when flexing.

    Remember, these are technically not bump stops but actually spring helpers and are there to help control roll resistance not suspension travel, per se. Just an FYI.

    With that in mind, the bumps should in theory, be extended the same amount as the lift?

    I know this thread is pretty much dead, but for others coming in as of late, I would like to say that I disagree with you blacksambo.
    Those are bump stops and they DO limit suspension travel. They may affect roll resistance but primarily that's what the sway bar does. I have removed my rear bump stops completely (not recommended unless you have a lift) it does not affect roll/sway on my VX at all, still handles like it always did, but without the harsh jarring of the bump stops.
    3" suspension lift, shocks: Rancho 9000, tires 33"x11.5", wheels 16"x8", offset= 0, no front sway bar

    I gotta tell ya....our two '99's handle with ease. NO jarring or anything untoward at all. These are after all sport trucks...what do people expect, 1978 Cadillacs?? The parts we are all talking about rides about one quarter of an inch above the axel plate, motionless. Once under way they are in constant contact with the axel. I think, to expect touring car ride in a fairly hi-performance, legacy SUV is expecting too much, perhaps. Let's let the original design do it's intended job. Saw if you must, but do so at your own safety peril.

    Awe come on Sambo, you know none of us are thinking old Cadillac ride, not even close to that so don't go there. Many of us have or have had, other SUVS/trucks etc so we know how various types of trucks ride.
    If your 2 VXs don't make a slamming/jarring/bang sound/jolting vibration of rather significance, when you go over larger highway seams, or on a rough dirt road, or a rough gravel road, with any type of rut or horizontal dip or rise of any kind...then.....um....um....you can't be driving a VX.

    Going only 22-25mph on my rough, rutted rocky dirt road causes my dash mounted compass, on a hinge, to jump/bobble up and down about 1/2"....and the hinge is secure, not loose. That's the slamming vertical lift I get from the rut or gully.

    It also causes a very significant vibration in the steering wheel, significant sensations/vibrations and movement of the steering column.
    Could it be that your normal travels just don't take you on roads of this type, and therefore, you don't experience it?

    Just going by sheer statistics here, if say, 80% of forum members comment on a rough jarring/slamming/ride over rough horizontal surfaces, and only 2 say "I gotta tell ya....our two '99's handle with ease. NO jarring or anything untoward at all."......ya gotta admit, that's kind of odd, statistically speaking.

    All the VX owners that have commented on the jarring ride have come from different model years, different locales, different terrain, different mileage, different ages, different condition of the vehicle...and yet they all describe the very same issue, in the same set of circumstances....that would seem to make it a valid issue IMHO.

    Again, my only 2 thoughts I could come up with to explain this 2 vs. many many owners, is to theorize you to don't encounter the type of terrain that the others describe. .....and secondly, you just have a different perception/feeling of this event when it occurs?

    Point is....perhaps your driving just doesn't put you in such circumstances...and therefore, you don't perceive it that often, or at all.

    I legitimately can't think of any other possibilities for the stark difference of opinion.....

    there's my 2 cents
    p.s....I am not making any commentary about the function of the bump stops...what they are called or what their official function is....just discussing the slamming/jolt in the ride.

    I had to extend mine on the rodeo so my wider tires and wheels didnt rub.



    Cant say it does much for handling considering the weird handling I have now after snapping my rear sway bar on 7 mile rim this year.

    That can be repaired with JB weld & carbon fiber duct tape.....

    LOL. Still havent decided if I'm going to replace it. Handles a little weird but not horrible. The back end tries to roll while the front stays flat-ish.

    I'm going through the same thing with the front sway bar. My sway bar links were shot and making alot of noise over bumps so I removed the bar to source replacement links. Now I've been driving around without it for a few weeks and its fine. Theres a little more body roll without the sway bar but the VX rides over bumps much smoother.
