Offroad Trailblazers and Envoys

Review my Build Plans?

BDS, ReadyLift, Smaxx... You name it, we know about it here.

My plan is to do a 2-2.5" inch lift on my 07 Trailblazer with 240,000 miles. Heres what I have so far from researching.

SUSPENSION LIFT

BDS'S Suspension Lift or Liftmeister 2.5"

ALTERNATIVE SPRINGS

Rear: Z71 Suspension Setup

Now my questions for this is, if I do the Z71 Suspension for the rear, say I go for Liftmeister 2.5" lift setup, do I need to put the lift spacer/block in the rear with the Z71 or does the Z71 lift the truck up itself matching with the front height? Also, where would I purchase the Z71 Suspension?

SHOCKS

Front: Bilstein HD Shocks

Rear: Bildstein HD (If I don't go the Z71 route)

TIRES AND RIMS

Rims: stock for now, will upgrade later down the line. will keep 17-inch size.

Tires: BFGoodrich KO2's 265/70/17

OVERALL AND REVIEW

How does this all look? Anything I'm missing or not understanding? I would like to have more appearance aspect to the truck by not doing any crazy lift or tires. I'm inspiring my build a lot from snowblazer.

The lift kits come with a 2” rear spring spacer. So either way using stock springs or upgrade to z71 your gonna need a longer rear shock. I would recommend a bilstein 33-185552. You can get them on amazon for $74 each on prime. If your front springs are original I suggest new ones maybe something a little stiffer. See the moog spring thread since the GM springs are hit or miss getting them

Also don’t forget the armor oil skid plate and radiator skid plate. see our MDB fab in our vendor section.

Lift block + springs in the rear. It may feel high in the rear at first, but the Z71 springs do settle. If you don't like it, its not that difficult to take the lift blocks back out - not like the front.

Buy the Z71 rear springs on ebay: https://www.ebay.com/p/Tahoe-Rear-15234 ... /655264827

Will having the Z71 springs + the 2.5-inch block make the truck sit unevenly with 2.5" in the front?

The trucks are already nosedived a little straight from the factory, but yes, Z71s will add like another 2 inches on top of the lift block. Like JD said, if you decide you can't handle it after they settle down you can always pop the spacers out real quick. Easy, just jack it up until the axle hangs and maybe take out shock bolts if you have to.

I have Z71s and 2" blocks in the back and '87s with 3" blocks in the front, and if I took my winch bumper off the front it would probably sit darn near level.

This is a comparison between a stock truck and a 2" BDS lift (front and rear), Z71 rear springs, and 32" tires. The rake isn't objectionable, even before the springs settle.
