Well today I dropped my Daily Driver, the truck is a '04 Crew Cab Z71, I only use the 4x4 to get to work in the snow and I love the lower stance and handling of a lowered truck and decided why not! I Used the purple GM torsion keys, Beltech 2" drop shackles and removed the factory lift blocks. The truck actually rides great, I couldnt believe it, cant actually tell any differance from the stock ride!

 

Looks good, but that looks like it sits awfully high in the front for keys and spindles...

EDIT: Unless you meant to say shackles?

 

lol, yea I typed spindles and meant shackles, my bad! Ill edit that out!

 

I wouldn’t expect that you would notice too much of a ride penalty, as you’ve basically done what GM did to lower the SS and Denali trucks outside the installation of the Belltech 2” drop shackles. Just for reference, GM removed the rear lift blocks on the SS, but left them installed on the Sierra Denali & C³’s and as such each had their own ride height. You may have done it and just didn’t add it to your write-up, but if not, something that you also may want to do is remove the rear snubber extension brackets and mount the rubber snubbers directly to the frame rails to prevent early bottoming out. It will give you an extra 1.5/16” of clearance. Another item that can improve handling and ride somewhat is the installation of the front snubbers from an SS. This is an item you would just have to check out the part numbers for your particular truck, as while on the earlier 4WD’s, the parts were specific between the two, GM appears to later installed the SS style pieces on the regular 4WD’s as well. You can do a quick check without getting into looking up part numbers by just checking out the appearance of what you have installed on your truck. The SS pieces are just black rubber, while the older style 4WD pieces were a yellow-ish rubber. The stock SS Bump-Stop’s are part # 15161761 for both sides.

Here is a comparison shot between the two. Ignore the difference from one part being used.


You could also replace the factory jounce bumpers with Belltech 4923 bump-stop’s. They are a little shorter and softer than the factory pieces.

If you do find you want different pieces, Belltech has the part numbers below.
4922 – 1.26” tall x 2.5” O.D.
4923 – 2” tall x 2.5” O.D.
4924 – 3” tall x 2.5” O.D.

 

truck looks good, needs lots of colormatching to set it off

 

What size wheels and tires are you running now and what are your fender measurements?

 

The tires are P275/55R20 on stock caddy wheels with bowtie center caps, the height to the fender is 33.5" all the way around!

 

looks great. I lowered mine the exact same way. I'm planning on going another 2" in the spring with spindles and hangers

 

Looks good. Was it easy getting front end back in alignment?

I had all the stuff to do my truck, then chickened out and sold everything, lol

 

Now that I got a Z71 I can't see lowering a 4x4, but it's your truck. Now debadge it and color match it.
