5/7 drop bishes

[rigo_jones]

have djm 1800 shocks i got on ebay for $42 shipped they are new i heard these suck but idk.

uhmmmm i didnt measure stock height.

i can get some pics... also i had my front down to 29 inches but my stock shock maxed out.

how much do you think the 4 inch tb springs will drop a tahoe?

 

[NORCAL SS]

yah 350s are soft i know.

if you want 29 inches in rear your going to have to go with a short spring. But with 8 inch springs in rear your shocks are going to have to be short so spring doesnt pop out.

450-600 is the spring rates to go with just a matter of getting the right height.

the 8 inch springs come in either 400 or 500 which are both good but id go more toward the 500s.

yes tony your right this is very important to not have a long shock that will let these qa1s pop out. the shorter and stiffer you go the more important is to keep the spring in. ill go with the 8-500 and cnotch i have a set of djm shocks extenders that i didnt put on since the shock was short enough for the coil not to pop out.

is there another way to drop the truck more with out messing with suspension? like the rubber mounts between the frame and body?

my z71 doesnt look that dropped and got me thinking if they used different under carriage mounts for the truck to be more lifted as its a z71 with off road package.

rigo do you hae shock extenders on it now?

at 32 inches at ride height right now with the shock extenders in right?

DO me a favor measure the following

1) Spring height from top to bottom at ride height
2) ONLY if shock extenders are in measure shock from center eye/eye at ride height

Do that then I can go from there to set you up better on what your looking for. also you can ditch the rubber bushings for now.

JK did a body drop with s10 body mounts. He has since removed them and reinstalled the stock body mounts. You will need backets for your bumpers to realign. A roll pan would take care of the rear bumper. By doing this you will drop an 1".

djm lower arms with spindles sits nice

do you know why he took them off? i guess an SS bumper will help with the front too.

i have djm lcas.

 

[NORCAL SS]

shock exenters will help ride cause the shock will have a chance to move up and down not have side load on it.

id look intot he rear djm kit also will fix the swaybar issue and has trailing arm brackets

So the 10-350 springs are essentially a 4" drop coil for these trucks, maybe 4.5" at most. Seems like the only option for lower springs are the 8" or 9" with a very high springrate to maintain ride quality and prevent bottoming out. I personally don't mind a stiff spring as long as you run a good shock it should ride real nice. Kinda weird that my belltech 4" springs actually sit lower than the 5" mcgaugheys, djm, and those 10" qa1

That sucks but I am in the same boat with you, my 4" DJM coils sit lower than the Belltech 4" kit and the McG 5" kit, WITH isolators!

 

[NORCAL SS]

it all comes down to what do you want to sit from ground to fenderlip.

honestly on his truck once he does shock extenders his ride should improve because the shocks wont get that horrible side load force that hes getting and will have a chance to actaully work.

also shock height will start to play ie at 8 inch spring height ride height at 32 inches with shock extenders your prob at 16.5 at ride height. now if your going to put a 8 inch spring in you will have to get a shock that has max 16.25 extended length so shock doesnt pop out. you can get away with 16.5 length due to the way the center of the lower mount is.

 

[Max]

Pretty sure you had 5" djm as they do not make a 4" coil Modded. My truck sits just a hair lower than a buddy's 3/5 with the isolators removed and the exact same tire, same truck, spare in tact, and he has a larger speaker box.

 

[Modded]

Oh they don't?
Well either way its a beautiful stance, for some reason I don't trust these Qa1 springs, they look prett sskinny/small to handle an almost 3ton SUV.
So how did it ride Max?

 

[NORCAL SS]

dam 32 inches is high im at 31 inches with a 1.5 drop on 265 40 22 on my wifes trailblazer ss lol

 

[Modded]

About 33.6 on all four corners on my Tahoe.

 

[Badluck]

"do you know why he took them off?"

I don't remember. We were pm'n back and forth about it. I just remember he said he went back to stock.


"i guess an SS bumper will help with the front too."

Not really, you are going to have to have to move the bumpers down an inch or they will interfere with the grill in front and hatch in back.

Rode ok but he could use some better shocks. My truck rides significantly better.

i cant shock is 1/2 short with the djm extenders i can put weight on the back to get it to go down an inch but i think it will break the shock since its whats going to hold the rear 1/2 inch lower. i dont get it why is it not going down????? is it the tire size? this is pissing me off! if it dont go as low as i want with cnotch, new strings and spindles im going to sell this pos and get a crew cab or a dually. **** this.

never mind it did drop looking at my signature pic its a big difference. not as i expected but its low. will lower it and come up with a way for a panhard bar should be simple just need some measurements.

the shock is at such a bad angle thats why youned the extenders.

trust me drop down the spring to a 8-500 and you will be more than happy and you can use the shock extenders.

9-400 is a little soft on a trailblazer ss rear set up. Im now going with a 8-500 (helping a member on my site) the 9-400 dropped him 4.5 inches over the stock trailblazer rear and the tahoe/yukon rears are 280 pounds heavier than the trailblazers.

here are all the 8 inch springs that would fit

so you guys know you can also spot weld the rear spring on the lower spring perch if you want to go with a shooorrttt spring and still have movement. Did this on a trailblazer ss which uses pretty much same axle mounts for spring.
