One ton suburban question dropped pitman arm

[Irish1941]

Pitman is only on steering box, 10 bolt or a D60, makes no difference. And no difference in steering boxes 1/2 ton to 1 ton. Only 4wd to 2wd is different.
Anywho, Skyjacker makes them as do few other companies.
Remember, dropped arm adds leverage to box and frame rail. If you haven't yet, get the weld on and bolt frame on reinforcement.
One stop shopping.
