You might be able to eliminate the noise just by lubricating the sway bar links. If the aftermarket ones have grease fittings, 'articulate' (twist) them before & after greasing them to work the grease in.
If you buy buy a grease gun, get a needle attachment for it as well. That allows you to lubricate the lower ball joints and ALL the OE end links that don't have grease fittings.
