2008 GMC Yukon Denali XL Off-road Build

Hey Guys,

This is my first post. It's about time to get my wife a new car. She loves her 2008 GMC Yukon Denali XL and has finally agreed it's time to let it go.

I would like to turn it into a very capable off-road vehicle but still keep it's great driving ability for long highway trips. I need some advice on the build.

The current rear live axle (3.42 gear ratio) has Stabilitrak. Is this good for off roading or should I put a locker or Torsen Type differential on in it's place?

Should I add a Torsen type LSD to the front IFS?

Can the existing rear live axle or front IFS handle 33" to 35" tires?

What suspension up-grades would you do?

I will not attempt rock crawling (very much the wrong vehicle) but will be on some rougher roads where a wheel will be off the ground sometimes.

Thanks for your help!

Hi Guys,

I posted the original thread.

A local shop suggested I do this suspension kit. What do you think?

They also suggest 33" tires and a winch Cradle setup.

I am new at this. What do you think.
