I new I had over 90degrees of articulation and needed to get rid of some.
but I didn't realize I had almost 180degrees of the stuff. Today I managed to get my front end upside down while the rear still had both tires on the ground.

Other than new shocks what are some things I can do to get rid of or eliminate some of the excess flex.

I like the way the suspension works it's just too much.

I am running savage shocks because thats what I had laying around. I hope to get new shocks within the next month however I am going camping in a few weeks and want to get a handle on some of this flex

swamp_rat · 07-09-2006, 03:25 PM

id say fab up some limiting straps and bump stop type things

dezfan · 07-09-2006, 03:36 PM

Use a piece of fuel line inside the shock to shorten it.

rockschooler · 07-09-2006, 03:38 PM

what chassis is it on? thats insane amount of flex! and use limiting straps.

pics of your setup would be very helpful...without em we are lost to help you on wht to change to limit the flex.....and if you hvae a 4 link over abut 120* is impossible, the links start to interfer with each other

Monkeyboy · 07-09-2006, 03:54 PM

It's a home grown chassis.
I'm not sure I have a good spot to put limiting straps. I guess i'll have to expirament with limiting the travel of the shocks with rubber tubing internally and externally.

Here are soem pics

I already have the rubber tubing in place that came with the shocks. I guess I'll have to ad some more.

rockschooler · 07-09-2006, 04:03 PM

to make limiting straps get some small shoe laces and some wiring eyelits with crimp connectors and crimp the shoe lace in them and just cut the lace how long you want it there is a tread on here but i couldnt find it.

dezfan · 07-09-2006, 04:05 PM

Well that is pretty close to 180 degrees. Shorten them shocks.

Monkeyboy · 07-09-2006, 04:08 PM

I'll need to get rid of some of the up travel as well as the down travel.

tubing inside perhaps to limit the up travel?

I use 4 inch shocks on a TLT (similar kind of laydown etc) and have limited out half of the travel, and still get 60 degrees.
Could just be your shocks are laid down too much to effectively limit artic?

They actually do compress. at ride hidth the shocks sit right in the middle of their travel range.

rockwerks · 07-09-2006, 04:16 PM

I use 4" losi rear shocks, 1.25" travel......I have no issues because its desigend correctly......dont scab some straps on it. or jury rig some other bandaid.take the time to learn the suspension and fix it correctly.......

lets see a pic of it from the front. Im betting you dont have enough seperation between the chassis end of the upper links, also your chassis is too short on the top for the shocks you are using, make some stand offs to stand up the shocks to min of 45* angle they need to stand up a bit more..either by lengtheining the chassis a bit on the top or moving the lower shock mounts in. right now your shocks are doing no work....even fully twisted around the shocks dont compress fully........

also move the upper control arms at the chassis to the outside from the inside, that will help alot

That might also be a factor - get some fuel tube inside the shock, under the piston and that will stop any over-extension.
Then some external bumpstops like the pic /\

the shock arngle combined with the upper arm location is the problem not the length. stand them puppies up and let em work

dezfan · 07-09-2006, 04:18 PM

Or just add the tubing inside and out of the shocks until you can afford the new ones.

It's not a life or death situation, jeez.

the situation is not the amount of travel on the shocks it is how they are positoned....look at the pics......tubing wont help much if any because the shocks are not compressing more than about half the travel even with the axle fully upside down. the positioning of the shcks is totally wrong.

Exactly what he said!

Get some shorter shocks and get them mounted to the links!

Monkeyboy · 07-09-2006, 04:53 PM

I know I need new shocks. With a weklong wheeling trip coming up I don't have the money to buy new shocks for this thing. After the trip I will be getting new shocks. I just want to get this thing running a little bit better before the trip since I plan on driving it alot at the end of the long days on the trail.

some of you are hinting at the fact thatmy suspension design is wrong.

What is wrong with a suspension system with zero bind? on full scale rigs no bind is good then you have to factor in al the squat annti squat blah blah blah stuff.

I don't want to limit my travel with my links binding.

on my buggy I use bump stops to limit up travel.

I am seeing on my scaled down version I have way to much up travel I think I will start with limiting my uptravel with a tube on the inside of the shocks. seeing how it's hard to place a bumpstop on these little crawlers.

dezfan · 07-09-2006, 04:55 PM

And mount the shock on the link as well. It will indeed help.

Monkeyboy · 07-09-2006, 04:58 PM

my shocks are mounte don the links they are just mounted all the way down next to the ball end because they are so rediculasly long.

I can increase the angle of the shocks but I'll jack the chassis way up into the sky.

dezfan · 07-09-2006, 05:01 PM

After you shorten the shock w/ the tubing, you can slide it up the link.

This will also make the shocks "stand up" a bit as rockwerks and Unholy were saying.
