    different pitman arm from 4\"-6\" lift?

    i just went from 4in lift on the front to 6in lift, before the steering on this thing was tight as hell now she likes to wonder a lot more. i already had the drop arm on there but i wonder if now i need more of a drop? but most arm are advertised as 4-6in lift arms. any advise?

    did your 6 inch springs have a shim built into them??if they did it could be throwing your caster out.im not sure if this is your prob.but mine(the little ive got to drive it)seems to wander.im planning to remove the shim.when i flipped the axle in my jeep,i tilted the pinion up,just a few degrees,whata wandering pos it was then!put in an alignment shim,to reverse what id done and it handled beatiful.on 40s!anyone else????

    yes--infact it had a fairly good sized shim incoporated into the pack, but if i off it wont that create too much front drive line angle?

    thats unknown.im hoping someone else will have some input.im taking my chances w/ the pinion angle personally.id rather have it handle good.cant get to the trail if ya roll it cuz it handles like a$$.know what i mean.i dont know how much you know about suspension geometry,to put it in basic terms, if you change the caster angle to straighter up it will wander,pull in ruts,etc.the jeep was so bad if you hit the painted lines in the road,it would yank it over the line(into oncoming traffic no less)i used to call it my caster disaster!!!![​IMG]im not sure this is your prob,but it could be.ive been there so im pullin mine out and ill see how it handles.if its better,ill deal w/ the shaft angle 1 way or another.but i personally dont think the angle will be that bad.caster on the other hand is greatly affected by just a few degrees.i dont think the suspension companies should put them in.just my opinion.

    $hit man is your blazer big enough! i agree. i dont think they should put them in there either, how hard is it to take the shim out of a new spring? do i have to totally take the springs off the truck?

    Re: different pitman arm from 4"-6" lift?

    actually im goin up at least 2 more inches maybe 4.taking them out is easy to do,and actually easy to xplain.i just hate telling someone to unbolt their spring packs.it CAN be dangerous.i hate to sound like a jerk but this is really IMO 1 of those things that if you need to ask how maybe you shouldnt.id let a mechanic or front end shop do it.well id do it,but i work on cars for a living so that makes me the guy who would do it at the shop.try having an alignment done and see how it comes out,if the caster is out,have them remove the shim.or if its out take the springs out and take them to them and let them do it and put it back together and have it aligned.like i said i hate to sound like a jerk,but i dont know your mechanical experience,and dont want to see someone get hurt.like i said i work on cars,im not a mechanic,im a body man.but"i grew up in the shop".(my dad owns his own mechanic shop)the only thing i dont do is auto trannys.ive been to school for steering and suspension.i have done my own springs in the past and will do again,but every time i do it im sweatin till the center bolt is tight.i just know the force they are packin and have a deep respect for them.people can tell you if theres no weight on them they wont pop.that may be true in some cases but in this case were talkin arched high spring rate springs.ill give advice to anyone that asks for it,unless safety is at stake.then my advice is seek professional help.as is the case here.i may catch alot of flack over this but this is somethin that you may want to let a pro do.if anyone else tells you how to do it and you chose to,BE CAREFUL!!!i just dont want to see you lose an important body part if they blow apart.

    hey 1990 k5,i hope i havent offended you or pi$$ed you off.i just have a standard which i live by if im not sure a person has the equiptment or experiece to do something,i dont want them to get hurt,bottom line.if someone wantsme to lift their truck if they are talkin like a moron i wont do it.i dont need the money for the install bad enuff to put a (for example)16 yr old kid whose daddy is willin to pay whatever to shut his kid up so he can have 44s.it comes w/ alot of responsibility,and if i can not w/ a clear conscience,put an inexperienced driver in the air,i wont.heres a great example,i recently met a guy whose 29,and never driven a big truck.i talked him into lifting his truck,6"to startw/35s,then once he got used to it,putting in a bodylift to fit 38s.the same goes w/ giving advice.dont get me wrong im no better than anyone else,but if im not sure someone can handle somethin i wont tell them how to do it for their saftey.ill help them and show them but wont tell them to do it,unless they have someone who has done it, to supervise for safety purposes.i hope you understand,and i hope some of the others here think the way i do,and will back me up.its all about saftey.

    hey!had a brainstorm!put on xtended shackles!itll pitch the pinion down a bit.maybe enuff to help.plus youll gain an inch.(w/ a 2 inch shackle).does someone make a 2 inch shackle for GM??ill check let me kno if you find any.well i went to ORD,they only offer heavy duty w/ a 1/2 in. liftor 1/2 in. longer.i couldnt tell.i really dont care much about the xtra lift,its the pointing down the pinion a bit i like they even mention helping the caster angle,to help w/ wander.
