Thanks for the suggestions.

What are the primary differences between the Skyjacker Single-Flex kit I have installed and the RE Long Arm kit? Just curious. Wish I'd done more of this research BEFORE the shop talked me into the Skyjacker kit.

Regarding a long-arm upgrade, any suggestions on good kits?

Regarding caster, I'm not sure (I'm a bit of a newbie when to comes to all of this stuff). I took my TJ into a shop to have it aligned and the mechanic was talking about caster, etc. That was the first time anyone had explained to me what it was...although I still don't know what it should be set at. We decided not to align it until I'd decided what to do re: the track bar.

Finally, why only replace the front track bar? Why not a rear adjustable as well? Just curious...

Thanks to everyone for your advice and suggestions. Much appreciated!

	Track bar A track bar is a component of a car suspension system that provides lateral location of the axle. While the purpose of the rear suspension of an automobile is to allow the wheels to move vertically with respect to the body, it is undesirable to allow them to move forward and backwards, or from side to side. It is this latter movement that the track bar is designed to prevent. It is a simple device, consisting of a rigid bar running sideways in the same plane as the rear axle, connecting one end of the axle to the car body or chassis on the opposite side of the vehicle. The bar is attached on either end with pivots that permit it to swivel upwards and downwards only, so that the axle is, in turn, allowed to move in the vertical plane only.

	Caster Caster angle is the angular displacement from the vertical axis of the suspension of a steered wheel, measured in the longitudinal direction. It is the angle between the pivot line (in a car - an imaginary line that runs through the center of the upper ball joint to the center of the lower ball joint) and vertical.
