bump stops

[ZJ_Rick]

Can I get the bumpstops for a budget boost by themselves.

[CincyZJ]

Have you tried Tera Flex web site for contact #'s

www.teraflx.com

depending on cost you might be able to jsut stack washers to comes up with the same spacer height, just a thought, prob be cheaper

I wouldn't even sweat not extending bump stops for a budget boost. I went to 3" without extending mine with 31" tires. I didn't extend my bumpstops until I went to the Tera + spacers. Yea, I had some rubbing but I also did the Con with no damage...from that anyway :D.

Fronts: Daystar p/n KJ0910BK (pair, 2" diax5"long)

Rears: Rusty has replacement urethane rears


The fronts that I recently ordered with the Daystar p/n are a much higher durometer (harder) than the previous two sets I had. The earlier ones were being eaten by the coils and the new ones seem fine.

What are bumpstops???

[George Frampton]

I ordered Rusty's "extended" rear bumpstops when I went to Rancho+BB. His rear bumpstops were the same length as my OEM. He hasn't solved the issue over the last couple of months, that I know of. The fronts were indeed 2" longer, as promised.

[MCracco]

Yes, it was my understanding that Rusty's rear bumpstops are the same dimensions as stock. My reason for replacing them would be the stock parts are gum and Rusty's are poly.

I'm with Kevin, what are these "bumptops" you all speak of?

[TOOLman]

OK, I'll show my complete ignorance here...

Is it the rubber thingy at the end of the...what's its name...the "pole" that the spring sits around? I believe it's there to soften the impact if you should compress the spring so much that it "bottoms out".

I'm probably way off here. I'm tired. I can't even think straight.

[MCracco]

The official Mopar term is a ‘Jounce Bumper’. We have begun call it a bumpstop presumably because it is a Bumper that Stops upward movement. Toolman is correct; in the front it is located in the center of the spring, in the rear it is on the frame positioned to contact the axle tube about a foot in from the wheel. The purpose of the bumper is to prevent over compressing the springs and keep the suspension in the designed operating range.

I think Anthony and Kevin are pulling our chains on this one :D

[MCracco]

Absolutely. But when they start to suck people in with that kind of nonsense I do wonder what the motivation is.

[Anthony]

Wasn't trying to suck anyone in. Just a little light hearted humor. Those who didn't know what they were found out. I was just trying to say don't need bumpstop extensions if you stick with sane tire sizes.

Funny - I called Tera this morning on this very topic.

Part numbers are for WJ's - I'm sure you change the last letter to Z or something.

Front bump stop kit for 2"BB - BSSFW - $40 (retail)
Rear bump stop kit for 2"BB - BSSRW - $28 (retail)

For $68 I will make my own from some bar stock aluminum or steel that I get at a hardware store for $5.

The technical support guy at Tera did say that if you don't run bump stops and you are disconnected and off-road you could prematurely fatigue your factory springs and have your jeep start sitting funny. Not sure how true it is, but that is their line.
