My lift/suspension Plan..Need input

[GreatLakes]

Hey guys. First post here. I've researched and read many posts both here and trailvoy.com. I have it pretty well planned out just looking for input/critique.

Truck: 2006 chevy trailblazer LT. 143xxx miles. 82/83 front coil springs. No G80. 3.42 gear ratio. 235/75r16 Firestone Destination LE2 with 8/32" tread remaining. this is my daily driver.

My Build Goals: "firmer" ride. capable of mild offroading(logging roads,getting to remote hunting/camping locations). More rugged look. I want higher frame to ground clearance and some increase in approach/departure angles. I don't mind a decrease in on road driving because my commutes are quite short.

My Plan: 2-3" suspension lift all around.
Front: 3" lift
Moog 81114 springs(my calculations show about 1" lift over oem springs(82/83)
BDS or Rough Country 2" front spacer(The BDS seem preferred but Rough country is half the price)
Bilstein 4300(24-103336) Struts

Rear: 2.5" lift
Moog 81069 springs(my calculations show 1.25-1.5" lift over oem springs)
1" spacer blocks
Airbag 1000(kept pretty soft unless hauling trailer)
Bilstein 5100(24-185783)

Tires:
BFG KO2: 245/75r16: 30.4"
BFG KO2: 265/70r16: 30.6"
Grabber AT2: 245/75r16: 30.6"

Can you see any changes I should make? Are my calculations for OAL Lift pretty accurate?

Seems legit. Nicely thought out and researched. Well Done!

Looks good to me... Having said that, I have radflo in the front, and the front-rear feels fine with stock springs, a 2" lift block in the rear, airlift 1000 bags, and the 5100 series Bilsteins. Others have the Tahoe springs in the rear or the ones you said, and they feel fine, as well, so there's that.

Looks like you have a good plan for the suspension lift. What tire size did you get?

[tgudina]

did you end up doing the lift? if so do you have any pics?

the moog 81114+2" spacer made my front end topped out at rest resulting in jolts and bangs over the smallest bumps and would've lead to premature front end wear. It did yield around a 3.5" lift. I removed the RC 2" spacer and replaced with standard top strut mounts. the result is exactly what I was looking for. the combo of the bilstein 4600 plus stiffer and slightly longer moog 81114 springs still left me with 2" of lift while not topping me out. the moog rate is roughly a 86/87 series spring yet about 1" longer uncompressed. the result is firm and tight while still letting the suspension do what it's designed to do.

I paired the rear z71 springs with the RC 3/4" spacer giving me a nice 2" lift all around.
