bars will always help it out only thing you will notice when you lower it 3-4 rear bar will face toward the ground this is why the shorter links I like better.
as others posted that I sold them the complete spohn kit it improves the rear a lot. the uppers wont work unless you weld on the tab for autoride.
On my truck I have the
DJM REAR BAR
DJM REAR LINKS (moves swaybar over)
SPOHN PANHARD
SPOHN DEL SPHERE LOWERS
Truck handles great but I dont drive it all the time my wife does but even with the 24s and big potholes here in san francisco it still rides great.
the 2/3-4 kit and the front/rear swaybars is the first mods I do to one of these trucks.
