These are a very nice option to lift the front of a 2wd Titan or Armada. These spindles simply "push" the wheel/tire/hub/brakes dwon 4" and keep the rest of the suspension in the same place. The shocks, a-arms. end links. etc are all in the same place as stock...very nice and easy to install. These also give 4" more ground clearance under the a-arm/cross-member. These come with very nice braided brake lines too. no special tools are required to install. These are heavy and typically drop ship driectly from Maxtrac.
