I've looked everywhere for a tow bar that would hook up to the welded on D hooks on my Warn front bumper but, other than getting one custom made (quotes ranged from $350 - $600) I couldn't find one off the shelf, and still haven't found one.
BUT - I did find one that a friend of mine has been using for years. NAPA has them for $220. Its only about 26" wide, fits nice between the D hooks, and is rated for 3500 lbs but looks alot beefier than any of the other off-the-shelf one's around. My friend has towed his TJ (5.5 RE Long Arm, 35s, winch, over top storage rack - yes much heavier than stock) all over the state with it and says it tows great with no trouble at all.
I went ahead and bolted it on but could've easily done a little fabing to make it fit the D hooks on the Warn bumper. Still may do it another day.
