I've just read through the archives about all the rear drop jazz and know all of the uptravel issues as well. Here's my question: Why are you all so obsessed with rear drop when your front axle hardly moves?

Here's my opinion: In this pic, John has enough rear "drop or flex". I like that set-up of good travel, but not extreme. http://www.expeditionexchange.com/retainers/DCP_1151.jpg

Now for front flex...you need balance. The B-S ers truck is balanced in this pic because of the excellent (relatively, considering radius arms) front articulation. http://www.rovertym.com/wheeling/img105x.jpg

Not picking on anyone (sorry Tom, you had the best pic to use :-) ), but he has great rear flex, but the front is stiff as hell. Look how leaned his truck is here. http://www.discoweb.org/tompearson/leftfront2.jpg

That's a truck that will lay on it's side well before a balanced one. The trick to performance is balance. Flex the front like the rear, otherwise you're gonna get tippy and only *look* cool.

Personally, I'm done with the rear. A bottom eye mount, stock upper mount and home-made straps on my Rovertym springs with 2" spacers (the spacers are going soon, but they were essentially working as bumpstops since I used the stock upper mount. My uptravel and stuffage in the rear is excellent.

Now for the front. My 9207s aren't cuttin it. even with extensions and some eperimental RTE stuff, I'm limited by shock extended length. When I've run with out front shocks, the performance is phenomenal.

So Guys/Gals, what do you think? Please no three link debate here, just theory.

Well, in Toms pic his rear wheels are flat on the ground so he isnt getting help to his front springs by his rear opposite tire stuffed which would transfer weight to his front spring helping his truck to sit more level. The rest is a couple of stealth things...lol. Its a game of gaining quarter inches. Call me...and lets see what we learn with other posts and thoughts.

Balance is good.
If you are limited by shock extended length, but you have plenty of compression left,
then spacing up the bottom mount would utilize the current shock to its fullest.
If you want more travel, I would try to put in taller shock towers and run a longer shock.
You may have to move the airbox.

Thanks Clint for the ideas, but I'm pretty much set with what I'll be doing. I was interested in hearing from the people that go for huge rear-end flex without thinkin much about the front...possibly assuming it can't be done.

John, I'll shoot you an email or a call..we got some good news.

Because you dont really need to Shane. All the drop you can want is there. You just have to do allot of little things to get the drop you want. I consider that an art......

lotta flex, no flex, some flex, who flex, who cares?

you will find that there are millions of little variables out there. like john said, my pic is totally different from a physics and geometry perspective as his. sometimes perfect balance is the perfect key. sometimes all around stiffness is, sometimes more front flex than rear would be great, sometimes my rear massive flex has save my ass and kept me level -- dropping down a steep incline, turning, and my front end flat as the rear stuffed up and the truck stayed pefectly flat. a jeep with massive front flex and little rear was totally on a huge angle.

in the past i did the KKC and compared my truck retained (more equal articulation) to not retained. didn't really notice a big difference. made it up the same stuff both ways. rear "felt" tighter, but I seemed to do the rover wheelie more easily. i dunno.

i will admit a dirty little secret. i enjoy the amount of flex when the eyebrows go up and people in other off road rigs look down-nosed at the rover. lets face it, big flex always gets cheers from the general off-road community. in the parking lot at my favorite spot to wheel, i drive that puppy up the ramp and gain instant approval when I out-flex thier rigs. consider it scoring one for the team for posterity sake.

all that being said, go back to the original picture. imagine that that is a rock instead of a forklift, then take away my amount of drop in the rear. the drivers rear tire would be in the air. would that be any better?

Tom,

Excellent points, thanks. Please remember also that I wasn't specifically picking on your rig.

This is what I want to hear. This is good stuff. Let's hear some others chime in!

As I have said in the past , the rear wheel forklifted pics do nothing for me and have been proven to mean nothing over and over. However , you get a forklift on a front right and one on the left rear and jack em up till the truck starts to get cocked and you are doing something. All kinds of things strart to come to light then , such as those long ass bump stops preventing some good stuffage..Also , lets get some weight in the trucks being shown off. I aint talking about a 6 pack of pepsi and some smokes , I am talking a full payload.
JBS ? Load that thing up like you are gonna do some thing with it besides drive around in circles and lets see what ya get :)

well as i keep saying. is there somewhere that flex is preventing you from going now that you are locked in the rear and TT in front?

usually for me it's a lack of ground clearance (thanks to a shitty spotter sometimes) or a complete lack of traction.

i just dont get it anymore

Top of pagePrevious messageNext messageBottom of pageLink to this message   By Kyle on Sunday, November 04, 2001 - 12:54 pm: Edit

Well Rob. When you lift the truck you have actually taken away some of the things it does well. It would be nice to get them back the way they were before the lift.
You are correct however. I dont really se it as a handicap. If you really really have a need to get rid of some cash though I think thats what you should shoot for...
Some of the flexers think they are going places that the unflexy arent going?

Have you checked Brain how high you can get opposing tires with no bottoming or binding and have all four still on the ground ? I can get opposing tires 20" high with no binding or bottoming and all four still on the ground , truck body level. Ofcourse , mine will ramp about a 300 :).

Kyle,

Is that via the dual fork lift method, or cross axled somewhere?

Kyle

Top of pagePrevious messageNext messageBottom of pageLink to this message   By Kyle on Monday, November 05, 2001 - 12:35 pm: Edit

I think the suspension criteria should be cross axled tests with no binding or bottoming and a level body. You stop raising when any of those happen and take your measurements. That will show true progress.....

I've got forklift pics.... http://www.thatchedroofgarage.com/articulation.htm

That's stock... the only thing non-stock is the 245/75 tires... springs, shocks, etc., all-factory.

Top of pagePrevious messageNext messageBottom of pageLink to this message   By Ron on Monday, November 05, 2001 - 12:57 pm: Edit

I'm limited by shock extended length. When I've run with out front shocks, the performance is phenomenal.

Then the answer is easy:

Look at Adam Way's RR front shock set up. You can run a 12in or maybe even 14in shock without any bottoming out issues.

The other thing I would like to add it that shot stock bushings allow the front to flex better.

Finally why not upper mounts too in back. It allows you to run a longer shock without risking bottoming it out or overextending it. These two things I feel like are major potential failure points for shocks AND mounts. Bump stops and spring stretch limits (and also bushing bind) should be what stops the suspension, not the shocks. They really are not made for that kinda thing.

Ron

PS I have pics of Adam's set up if you can't find them.

Les , tahts the kind of Data that I find worthless. I posted what I think the criteria should be above. Tires on oposing corners should be lifted at the same time until something unacceptable occurs. Then take your measurements from that.


Kyle

Kyle, I agree....

I was just saying I've got forklift pics!

Seriously, my point was, that's STOCK... nothing modified....

The reason why were were messing around with the forklift was that we were generating as much stuff as possible to make sure that we had trimmed enough. While at it, might as well stick a tape there.... hmm.... now if we could find another fork-lift....

As far as THIS conversation goes, though; where such relates is that a stock rover has lots of flex... enough for most of us.

That's what I was throwing into the ring, Kyle... not saying that what we were doing was vaild for useful measurement purposes... we were 'doing' something else, and were just messin' around at that point...

I guess the problem here is that no one understands the wieght shift and the changes that happen when you crossaxle. If you are 1" off that bumstop on that fork lift you know whats gonna happen when you cross axle... :) How about a directory of those pics ? lol

I could never let you get off that easy. :) You mentioned something in another post about it getting you instant recognition. Maybe that is the best way to explain the uses of shiny shocks and and dropping rears...
Another thing that interests me is that I really dont see any slinkies doing any long range Expedition type shit. Mike Peters was in Moab with us and he truely does have a nice truck. I dont see many others doing it though.
You run that thing offroad loaded down Tom ?

John,

I gotta second Kyle's information. Without some form of password protection (not too hard to do, actually), anything you put on a publicly connected website is going to be open to the public -- published links and URLs or not. If someone wants to sniff around, he's going to see everything -- even without any real "hacking".

Kyle - My recognition post was a joke. Yeesh.

Do I do "expedition" stuff, no I guess not. Don't have the time and/or the other half that would enjoy it. Don't know if it would cause a problem or not. Even if it did, who cares I'd modify my setup as needed.

The simple fact is that everyone uses thier trucks differently and sets it up the way their tastes and pocketbook can allow.

To me, I don't care how the trucks are setup on the trail as long as the folks are fun to hang with.

Yeah, out on the trails, the Stage III is constantly crushing the bump stops, especially in the rear. I have gone through 3 in the past 12 months. We shall see if that # decreases with the heavier RT new springs. However, I dont have those spacers under the springs.

The effectiveness of all this is what we are talking about Tom thats something you seem to keep skirting. I do however agree with your previous post (Kidding or not) about the ohhh and ahhhhs. Thats where the bang for the buck comes in. John here is quite aware of a statement I made long ago about being tired of the publics perception of what all that is getting you. These talks arent about if you like it or not and how damn "Cool" you think it is. Its about all the people that hit this board and read it. Maybe they should have the full story on it eh ?

Kyle,

I am not skirting anything. I have no idea wether or not it is more effective with or without the cones with 100% certainty. I also have never been in a situation where I thought "gee, if i only didn't have those cones on...".

The bottom line is I just don't care enough to go through this all over again. It was fun while I was bored at work to pass the day, but now that I have some challenging projects underway, it is really quite boring by comparison. If the x-files didn't get stupid I might not be typing this right now, either.
