Product Questions
For the pitman arm hardware, may I purchase the shank nut, lock washer, and rod end? if not, could you let me know what they are specifically so I may go try to find the replacement parts? I believe it may be HP9077 that may have everything I need.
Hi Mark, The hardware you need is able to be purchased by contact our Customer Service Team via phone, email, or live chat. Both the nuts and rod ends are custom and specific to our PISK.
I have a 2001 1500hd chevy 4x4. Which idler and pitman arm do I need? I don't see a selection for a 1500hd. Thanks.
Hi Justin, You need part: 110-90715 for the '01-'10 2500/3500. The 1500HD uses the same components.
Will this kit work on a 2008 GMC 2500HD Duramax with a Pro Comp 6” lift also with Kryptonite pitman arm and idler arm
Hi James, It has been our experience that our PISK will not work on the Kryptonite pitman arm and idler arm.
