I put some drop shackles on my truck couple of months ago, ever since then every now and then the ABS light comes on. Any idea what it could be? Also who bent over the tabs under the bed when they installed theirs? I didn't and have noticed that they rub on the shackles. Thanks

 

Sometimes those tabs on the underside of the bed need to be bent back when installing lowering shackles.

I didn't need to on my 06 2WD when I installed my lowering shackles, but I did knock them back a bit just to be safe before I set the truck back down when installing them. Just used a plastic dead blow hammer to wack them back a bit.

My ABS light came on, but it was because the sensor was on it's way out. Replaced it today in fact. It was the rear sensor that went in the diff. Check and see which ABS sensor is throwing the code and causing the light to come on before just throwing parts at it.
