I got a Z85 and i was going to lower it with the 2 inch torsion keys for the front. Anyone have experience with these? Hows the ride after? Do you have to have a tool to change them? thanks

btw does anyone know how z85's are raised from the factory. i know 2 inch blocks in the back but how about the front? coils or torsion keys?

4x4's use keys, so to answer your question use keys to lower the front and pull the blocks out in the rear.

I think there is a tool you can get for the torsion keys. I've heard its basically a glorified clamp. The last time I lifted a truck, I used the jack on my lift and then some other type of make-shift device to ram the key to the point where I could get the lock thing in there. I'm sure it was highly dangerous, and I probably wouldnt recommend that route. I'd think since you are lowering it, it would take a little less force to rotate that torsion bar, but its still going to take alot. Allegedly, you can do this:

Take off the wheel, unbolt tierod, ball joints, and sway bar, oh and shocks. Completely take out the adjustment bolt on the key. Make sure the truck is up on a jackstand. If at this point if the torsion bar does not slide out easily then get a buddy to push down on the lower a-arm to "unload" the t-bar. Slide the t-bar forward, and the key should fall right out. Then put the new key in, slide the bar back and bolt everything back up!

Thats kinda what I think too. A dude that works for my dad has a 4x4 Tahoe that he slammed the shit out of. To top it off, he put a body kit on it. Now he can barely get out of the parking lot to the shop. But to each his own I guess.

sorry guys i guess i wasn't clear on which z85 i have. it's a 2006 GMC Sierra. has torsion keys in the front, and of course axle under leafs in rear. no it's def. a 2 wheel drive, no coils.

*EDIT*- when i originally started this thread, the truck was new and i was not knowledged on torsion keys at all, which is why i was wondering if it had coils in the front. without even looking at the truck i jumped on the internet looking for lowering kits

So you have a 2006 Gmc Sierra z85. What motor and seris is it? 1500,2500? I don't just understand two wheel with torsion bars. Something is not right with this picture!
