I've seen reference to their spindles being used to drop a 4x4, but their website gives no indication of this being the case.

 

Yes you can use those on 02-05 4x4. ive seen a few threads on other sites where guys have done it. the dont list it on there site for liability resons or something of those sorts.

 

Thanks, I'll look into this.
My Ride-Right Firestone airbag helper spring system just took a crap on me, (I have a slow leak to find) so I'll prolly be looking for an alternative that allows cargo capacity plus lowering capability.
