finally an upgrade to crap factory bump stops!

MIGHTYMOUSE · 06-23-2009, 06:01 PM

these are for a jeep. they were cheap and they bolted right up!

since i am trying to keep my midwest rear end from beating up my gas tank, i had to do a little work to the slp bump stop spacer to re-use that.

check it out!

factory stops are GROSS!

making the spacer work (do not need if the car didnt allready have them)

beautiful!

real excited about that one.. man i hated those factory stops!

I'm using the same parts on my car. However, I trimmed the bumpstops to clear the "lip" that is left there by the factory.

Would someone not running 8 second passes need these? My stockers don't look like they have ever touched the axle.

where did you get them and what is the part number? how much were they?

I've been on the bump stops so much that it's polished metal where it hits.

Mine don't look that bad, probably because it's dry most of the year. Again if you didn't have the spacers you don't need them?

Nice find!

Yeah the stockers were square. No wonder they sucked. The stock z28 triangular rubber ones I prefer. Gives a little more progression into full suspension travel over poly.

First picture.

You can also get them in black.

I've heard that those are hard poly and it hits very hard on them. Is that true?
seems like softer material would be better.

I would think you'd have to be doing some hard driving to be continually slamming the bumpstops. As I previously stated, I installeed these pieces on my car. I have a '96 Z-28 with the Eibach ProKit springs, and at ride height, I have 2" of space between the bumpstop and the axle. You've got to hit some really big bumps at speed, to compress the suspension 2".

Well poly is always stiffer than rubber. I think there's more contact with the axle bumpstops than most people realize.

MIGHTYMOUSE · 06-24-2009, 06:07 PM

its not like hitting steel, it does its job, i hit mine from time to time and which means i am not hitting expensive shit on other expensive/flammable shit.

MosesMcgregor · 06-25-2009, 02:50 PM

couldnt have found this at a better time! I just noticed my 9" filler plug has been rubbing and eating away at my fuel tank

firebird6786 · 06-25-2009, 03:32 PM

where did you get these bumpstops and whats the part number!????

The very first picture shows the part number on the package and you can get them at any autozone, pepboys, kragen...

I'm wondering how these are an "upgrade".

I'm wondering why the hell anyone would expend any effort to retain the SLP spacers.

And to the guy who thinks you'll only hit the stops under hard driving.... you could not be more wrong my friend.

MIGHTYMOUSE · 06-25-2009, 06:02 PM

these are an upgrade cuz they will not fall apart like the stock ones did

my car is lowered, thats why i need the stops / want the stops

the slp spacer lets the stops hit sooner, which is imperative given the set up i have tq arm wise from compromising the gas tank.

Ironhead · 06-25-2009, 06:21 PM

A hard poly stop adversely affects ride quality and handling performance because when you contact the stop, the effective spring rate of your rear suspension spikes to somewhere near infinity.

Can you see how this may also affect a drag car on the launch? Exactly how much of a detriment this would be I am not qualified nor experienced enough to say.

My car is lowered. That and the above are why I want / need the softer factory Z28 stops. Note: NOT the SS stops.

Yes, the SLP spacer needlessly decreases the available suspension travel. Not good on a car that is already lowered a good bit on Pro Kit springs.

What torque arm do you have and how does it contact the tank when the tank is well aft of the arm?

I admit that on a drag only car that sees no street duty, some of the above may not matter.

You can always make your own. Grainger and other companys sell resins/urethanes of different levels. you can get stuff as soft as a pencil eraser and as hard as the stuff the LS1 intakes are made of.
