I feel like you are confusing 74-76 with 84-86. Considering max width in most orgs is 80
For sure! I actually looked into those racks right after you first mentioned it. Thanks again for the info.David, I think I mentioned a few weeks ago that extending is allowed but you have to be careful even moving the front arms forward 1-1/2" to 2". Some long travel kits get the 2" for 32' or 33" tire clearance. My point is when you move the front arms forward (all long travel kits do move forward 1-1/2" to 2" you change the angle of the tie-rods into the steering rack. That slight move forward will destroy the stock rack because of the design and angle changing.
Shock-Therapy makes a beefed up rack from billet aluminum ($995) a must if you move the front arms forward from stock position.
