Ported Steering Box Option: This option gives you the ability to upgrade later and add steering assist cylinder kit. If you are considering this option or wanting larger tires be sure to get the ported steering box.

Allowing you to travel at high speeds going down the highway in a straight line without drifting. Decreasing the effort it takes to turn those massive heavy tires. This will also increase negative camber gain while turning for wider tire contact.

No Welding Required: Making for an easier installing that is 100 percent bolt on. (with factory tie rod configuration)
