Drop Pitman Arm needed 6" Lift

I have 1, what does it fix and is it necessary?

Death Wobble ?

Bump Steer ?

Re-alignment necessary if i swap it out keeping everything aligned and in place? I'm sure the drag link will need to be shortened up but everything else should be fine correct?

ICON 4.5" Lift + 2" Spring spacer under pad.

Extended the Drop links, extended the shocks,

TIA

Denny

I'm not 100% sure what you're after here, but here's what I think you're looking for:
*Death wobble is usually the need for a steering stabilizer (or better shocks I can't remember exactly which) in a coil sprung Souper Doody.
*Bump steer is from a misaligned steering system, ie a lift without a dropped pitman arm.
*While the camber and toe was most likely unaffected by the lift, the caster needs to be checked after lifting a 2005 and up truck.
*If that lift/spacer are installed without adjusting and/or lowering the trailing arms, see the statement about caster.
*Extended sway bar links will allow the sway bar to work properly. Same for installing longer shocks.

I hope this helps.

A drop pitman arms purpose is to lower the steering angles to prevent bump steer and so is a drop track bar bracket. Your drag link when it gets kinked on the tierod ends cause major bump steer when you hit a bump and can cause a death wobble. You always need to have the draglink and trackbar at the same angle.

My draglink is custom with 1 3/4 heim joints and the ball joint on the axle is flipped so my angles can be perfectly the same. No bump steer at all. You must run a drop track bar bracket and pitman arm on a 6in lift.
