3 or 4 Groove Pitman Arm?

[SmokeyJoe]

I recently purchased a bunch of parts to lift my 2007 H2. Trail Duty sent me the 4 groove pitman arm.

Is this the correct one for a 2007, I read on here somewhere about a 3 groove or 4 grove.

You need the three groove arm. Make sure you have a good pitman arm puller. I took a 3" air cut off and cut two relief grooves in it almost to the shaft it can off nice and easy.
