Improving KK Handling

What are the recommended steps to improve the handling on the KK without lifting the ride height? I'm not quite ready for a lift for warranty/financial reasons, but I can put a few bucks into the suspension/handling system to make it ride and handle better.

Would poly bushings on the track bars help? Bwoody sway bar links? Any other bars, bushings, or arms that can be replaced and used with the stock struts/shocks to improve handling?

I know that the 'improvements' might be relative and the opinion of the owner, but to me the car feels mushy, soft, bounces around too much, and doesn't turn too terribly well...

Buying a jeep for the "handling" is like buying one for the gas mileage.

That being said, get some new front struts and rear shocks. The Bilsteins that came with my JBA lift took care of the mushy , soft, and bouncing around you describe.

Not sure what you mean by "doesn't turn too terribly well" as mine has a fantastically tight turn radius. If you mean that you cant do the emergency lane change test you see on TV , that's from the deliberately slow R&P steering that was probably engineered that way to keep you from rolling your "dangerously top heavy" SUV. Adding poly bushings wont improve on your still new rubber bushings as much as good shocks and struts will. They will however make the harshness of the road's cracks and potholes much more unpleasant.

What are you running for tires?

I guarantee that you will like your vehicles ride much better with a good set of shocks and proper tires than all of the poly razzmatazz you can find on the innerweb

I'm not looking to be in a racecar, haha. I'm also not an 18 year old throwing all kinds of cheap garbage into his car. I was just posing a question to see if anyone had done anything besides a full spring/shock/coil kit that helped them notice a difference in handling. I'm aware of what a jeep can and can't do.

I have BFG AT's on the KK right now.

My liberty(granted a KJ) handles better,brakes better,corners better,and generally feels better overall when I added 2000lbs weight,lifted it 9",scraped the IFS,added 35x12.50x15 tires,and run only the Currie AntiRock front swaybar.

I think JBA sells suspension components meant to seriously upgrade the KK without lifting it at the same time... someone correct me if I'm wrong. JBA's adjust a struts are developed from racing hardware. Of course, I would want the lift too if I was spending time and $$ fixing up the suspension.

The squish is coming from the stock springs. Nothing you can do about that but replace them with springs of heavier weight which will lift it a little. The BWoody sway bar links are supposed to help and can still be used if you decide to lift it. My OME springs make an incredible difference with the cornering.

Yes just replacing shocks will do little for handling, you have to do a complete system to balance everything out .
Stock springs and shocks are made to provide a very soft ride since thats what soccer Moms want, not good handling if you push them any at all

It seems that the best thing to do is just save money for some OME springs and bilstein shocks. I'll give the bwoody arms a thought too.

I shouldn't need the a-arms with a 3" lift correct? The rest of the stock hardware is good to go...?

For the few dollars more it cost I would go full OME springs and shocks. They are a matched system . With only using them you'll not need the JBA UCAs although they are a nice upgrade with replaceable ball joints etc
