12" on a Denali?

[LB7Nick]

Hey guys, I know this topic has to have been discussed before but I couldn't find the answer I needed when I searched. I have a friend interested in installing a Bulletproof 12" suspension lift on his 2005 GMC Sierra Denali 1500 and he was wondering if the Quadrasteer would cause any problems regarding the installation of the lift, and if the lift would adversely effect the daily use of the Quadrasteer system. Tires will likely be 37s or 38s. Thanks in advance for your help!

If I'm not mistaken when you lift a quadrasteer you cant adjust the pinion angle much because you screw up the caster on the rear tires. I dont think your going to be able to get even close to the pinion angle you need with a 12".

You will have vibration issues with lifting that type of truck.

I would have to agree with the above stated but and quick email to bulletproof would answer.

I believe this fellar has things to say that are smart.







PM bubba, he's in LA and would love to answer your denali 12" ifs lift questions.

I've yet to see a quadrasteer that high... I think you may have to lose the quadrasteer if you want to lift your DD that high!

The only way you would get that setup to work is if you cut and turned the C's on the axle tubes which would allow you proper caster angle and pinion angle. Don't know how that would relate to the actual Quadrasteer steering mechanism. Would have to be mounted a bit differently, I'm sure.
