droop is when the shock is fully compressed at ride hight (just sittin on a flat table) it lowers your COG, its just a different suspention set up so rather then your shock compressing to articulate on the rocks, it will be extending. basically take your spring off your shock and then you have a droop set up, how ever you will need to tune it with thicker oil, / internal springs limiting it with fuel tube to set your right hight, or chaning upper moutning locations if you want to get it to work decently.

if you use search you will come up with a ton of info thats more in depth then i am going

heres a thread thats got the basics of settin up droop in it Edge chassis help

This is a lil drawing I used to explain it to a buddy! Hope it helps!....The spring placement is the key factor!

Default Internal Droop and Spring

What is the benefit of having a droop or internal spring set up? Will droop lower a crawlers COG and/or its ground clearance? I am trying to lower my COG without affecting my ground clearance. Thanks in advance for your time answering these questions.

The link posted earlier was a big help in answering most of my questions.

the only differance between external spring and internal sprung is where the spring is, about all you gain is some clearance around the shock, but when you go to droop you will lower you COG and loose GC. they kind of go hand in hand. if you want a lower COG and keep your GC you will have to do things like get ur battery on your axle, add wheel weights put your electronics on your links or an axle plate, flip your shocks basically get any thing you can down lower then it is now

How much ground clearance do you have right now? how much do you want? Most comp crawlers that i've seen run between 2"-2 3/4" of ground clearance depending on the driver. My setup is running at 2 3/4" and I think it just the amount of ground clearance.

Thanks for the answer concerning the benefits of internal springs. I have about 3" of ground clearance with the standard Axial AX 10 shocks. I will have to see what happens to my ground clearance once I get some Losi shocks. I think I will stay with a standard spring set up until I get more drive time under my belt with my crawler.

Not really worried about comp crawlers. Have no intention of ever trying to get to that level in this hobby. I am just trying to get a sense of what is a reasonable ground clearance. My crawler at present has 3" of ground clearance. Which is good for here in NC. I will probably drop my crawlers ground clearance a little once I get my Losi shocks.

no problem, i'm running full droop and i have about 2 1/4" GC, when i had the stock chassis, i run full droop with about 1/4" of fule tubeing on the shock shaft on the out side, and had about 1 7/8" of GC, useing 1 pen spring inside each shock. and i found it much better then running a spring set up, its alot of playin around and tuneing to find what works for you,

great topic,
I'm also interested in running droop with the stock AX10 shocks and chassis.
The only thing that is holding me back is Ground Clearance.

I would like to at least get 2 inches preferably 2.5.

drill mounting holes lower on your chassis this will allow you to mount the shock lower which will move the chassis up, you will need to put 6mm spacers between the shock and frame to kee the shock body away

How do I know how low on my crawler chassis to drill the new shock holes? Let say I use Shock X (example only) and it drops my ground clearance 1/2". Do I drill new shock holes 1/2" lower on my chassis? Or do I have to learn my trial and error? When the shock moves the chassis up will that help bring back some of the lost ground clearance? I know this is an easy question, but my daughter has been driving me crazy all day so I cant think straigh.

easies way would be,

install shocks on axles, put somthing under your belly at the hight you want, then with the shock being installed at the axle end it will basically find where it wants to be on the frame by it self, all you have to do is move it around to get it in a good spot, mark 1 hole, drill it, clamp both chassis plates togeathger so they line up perfectly (yes you have to strip down your truck at this point" use the 1st hole as a guids and drill the hole onthe other plate, unclamp them and flip the top one left to right, reclamp and drill 2nd set of holes, thie will make sure all 4 holes end up in exactly the same spot on the chassi

Thanks a ton. Now I cant wait for my new shocks to get here and get them installed on my crawler. I will let you know Wednesday how all is going with the shocks and the crawler.
