rear bump stops

[Gizmo42]

Try them and see how it rides. Looks like they might be collapsible like the ones on my rodeo. Mine sit about 1" off the axle but I dont feel it until it fully collapses.

ok got the bump stops on.since i dont have a lift and was just replacing the original stops i wanted to keep as close to original height as i could.the e.s. ones are a little bit longer.
so i just took the old ones off and drilled a single hole in the factory mount location and with a bit of messing around with holding the nut with a wrench in side the channel i got em on.
they sit right on the rear axle.does that mean my springs are too weak?my original stops where all tore up.if so anyone know anywhere i can get new springs?

Nah. I would roll with what you have going on there until you really plan on making a lot of changes. Looks great for now. If you want to add larger tires, lift, etc, then I would worry about stiffer taller springs, but until then, good job :-)

ok after a couple days of driving i need a kidney replacement!wow it rides rough,like it has a fixed axle with the bump stops resting right on the axle it doesnt let the coil springs do there job.
so i need some input from anyone who is running the ome 913s on what the ride quality is compared to the stock springs...its gotta be better than what i have now.
i was also thinking about the Set of Daystar Spring Spacers to give me about an inch and a half lift to get the stops of the axles

I cut my stops and added the Daystar spacers after installing 265/60/18's on 8" wide, -2mm offset rims. Those spacers are like $35-40 shipped, if I were you I would order a set and try them out first - they may very well be all you need.

Low risk, big reward IMHO.

I did just the spacers and it made a big difference and was easy to do, since it was the second time I had done it.

Thanks again Billy.

WOW!!ordered the spacers from summit yesterday and got them today!!
and another WOW!! because what a difference in the ride after i installed the spacers.i used the stock spring seats inside the spacers but not sure if i will leave them in or take them out it sits a little high in the back with stock 16s it might be a little much.
here is a pic to show how much lift the spacers give keep in mind that before i installed them the bump stops were sitting on the axle.
pic is kinda dark..flashlight and cell phone lol but you get the idea

I suspect your springs may be worn out.

The official "before" measurements on mine were: 1/4" gap between bump stop & axle on the right and the left side was resting on the axle. I bought a pair of used springs and new insulators and now I have 1/2" both sides. Rides smoother and corners better. Even if you keep the spacers, I wonder if you would get the same benefits with fresh springs, too.

[vxfocus]

i did think about spring replacement but the bump stops i put on were longer than the stock ones so replacing the spring might not have lifted them off the axle enuff.so i went with the 40 dollar option.

Does someone have a part number or link to Summit for the spacer kit. Ive inferred its a reasonable mod for stock wheel size [I have aftermarket wheels and tires but same fitment]. I had how mine jar.
Thanks much...

If you would like a used stock set of springs to mess with, I've got a set that are yours for the price of shipping. I'm moving this week and they will be thrown out otherwise. Let me know if you (or anyone else for that matter) wants them.

[xdfarrx]

Thank you but I have a stock set. Did all my sway linkages with the energy stuff years ago. Thought I would update my stops. Dont throw them away, pay it forward or sell them. Good luck with the move

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.

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.

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.
