Yeah I'm getting some tires this winter break but I have been off road a few times with the bald tires and I have gone every where a jeep grand Cherokee could go so I'm pretty impressed

new tires will make a huge difference.

Yeah if any one has any other ideas to boost its performace besides shackles it would be alleviated

sway bar disconnects, a proper rear locker.

Why would disconnect the sway bar help?

Because disconecting the sway bar allows each wheel to articulate independantly, giving you more vertical wheel travel on each side, keeping all 4 wheels in contact with the ground longer when you're in rough terrain.

On the road they help keep the truck balanced and reduce body roll in corners by applying pressure to the opposite side when one side of the suspension is compressed. Ie. when one wheel goes up it applies upward pressure to the opposite side to keep the truck level.

Ok that makes sense. The other thing I'm looking at is 2in shackles. can I use a leveling kit on the front to even it out? Sorry if this a silly question but this blazer is my first 4x4 lol

good explanation!

In my opinion, the leveling kits that consist of just new torsion bar keys are a waste of money. You can turn your stock torsion bar keys up higher than what is safe for the CV axles unless your torsion bars are extremely saggy. If you do shackles (which are a great simple lift for the rear end) then just do a 1-1.5" torsion bar lift in the front for only the cost of an alignment, and put the money for the leveling kit towards something useful, like a real upgrade or beverages. :icon_beerchug:
