2011+ Power steering box into 2008... diagnosing, pics and tips.

I spent the day running errands with my truck. It steers like a dream now. Big difference, especially when parking.

I measured the pitmans. The 2008 pitman is about 5 7/8" center to center. The 2011 pitman is about 6 1/2" center to center. This should increase the steering cut for sharper steering.

Pitman arm length won’t allow it to turn any sharper. The knuckle hitting axle lock is what determines how sharp it turns.

I could be wrong, I was thinking he was referring to steering response. How much wheel movement you get for a given amount of steering wheel input. A longer pitman arm would move the wheel more for the same amount of steering wheel movement. This assumes the steering gear has the same ratio in the early model and late model boxes. If the late model box has a slower ratio then it might end up the same.

As you mentioned though, no matter the gear ratio or pitman length, the turning radius will stay the same. When the knuckle hits the axle housing, that's all you're gonna get.

Excellent info! I replaced my gearbox with a redhead when I started getting death wobble at 70mph due to excess slop. It fixed that issue but did nothing for ease of steering. Wish I would have done this swap instead.
