My springs in the front are leaning a little to the side. Is this due to trac bar length? I have an adjustable jks bar.

 

I'd say they are not seated correctly...

 

They are both in the grooves?

 

If both springs are seated against the bottom stop, look at the top rubber seat. The coil could be outside the lip. Measure from the edge of the tire to the spring perch on each side to see if your axle is center. If not, make the adjustment in the track bar.

 

If both springs are bowing outward equally and provided they're seated correctly, your spring rate is somewhat soft for the weight you carry. If one was bowed out and the other somewhat straight or bowed in it would be the trackbar adj and centering of the axle.
That said, if both are bowing outward equally, it really isn't a prob other than aesthetics.
