Using qa1 springs 5+ drop in rear.

[NORCAL SS]

max did you get the shorter shocks??? I just dont want anyone to lose a spring when going sideways up a curb. I would recommend shock extenders at least to anyone doing this and getting the correct length shock. I would try the 10-225/475 if your 11 inch spring doesnt work right.

this is pretty much a c notch i had to do on my blazer... cut bumpstops off then cut frame and weld a notch that was for it in.. i lost the picture of it all in there. ill try to get one side shot of total thing in.

as people start doing this ill just add results in first post ie tire size/ground to fenderlip measurments. not sure if many people will go with more than 5 inch drop though but if they do this will work out great.

Also its the same set up on the 07 up trucks

They shipped today and I have 19" extended length bilsteins sitting at work along with new fronts. I hope I can get just under the frame with the coil fully compressed and not bottom out, looks like it would sit another inch lower than it does now. I guess trial and error is the only method with these things but if enough people try these I'm sure we can build some data.

Hey max what is the part number on the shocks ur using cause that's all I need is the shocks i have everything else to use the qa1 springs. I am having a shop here in Washington do the notch in the frame but I need the shocks

I don't remember off hand I'll have to check next week when I install everything. I also have shock extensions.

Nevermind on the shocks, I will have to figure that out on my own. It would be kind of hard to use the same shocks if we use different springs. Disregard

Plus or minus an inch you'll be ok with shock extensions. I have a few lengths laying around just sucks I'm gonna have to press sleeves in them since the shortest gm rear shock is 22.5". 7" springs should work on a truck with extensions and a 19" to 20" long shock.

10 400 with qa1 ddr7855p thats what i think it was. I wish i could get someone here to go lower then 5 inches id have the info by thursday. Ph well at least ypu guys know the way to get these trucks down now. Btw the springs will settle 1/4 to 3/8 in a out 500 miles

Max have you looked into trying some shocks from the qa1 website? Just kinda curious
