i bought a 2001 chevy 1500 xcab. does any one know what is the speed limit when you are in 4wd hi? my other chevy's had a limit of i think 35 mph. the owners book say's nothing about how fast you can drive in 4 hi.also i'm thinking about putting a plow on it. do i have to beef up the front suspention? thanks for any info

I don't think there is a speed limit. Isn't a "shift on the fly" system. It used to be you weren't supposed shift into 4wd HI at speeds over 45mph.<br />If you put a huge plow you may need to beef it. If you buy a plow rated for your half ton truck, the plow dealer should be able to advise you.

I had 2000 Ford F-150 And now have 2002 and Have never had any trouble shifting in to or out of 4 high. It's 4 low that you must be at a stop, and in neutral to shift in to. And it is speed rated.

I have a 93 Chevy 4X4 and I have used 4 high up to 45 or so. I never really went any faster than that in 4 wheel drive. I guess I always just figured if I could go faster than 45 I didn't need to be in 4 wheel in the first place.<br />I do have a limit on my speed in 4 Low but am pretty sure there isn't one for 4 high.

Re: chevy 4x4

call a dealership on this one. Ask for service Dept., tell them you don't have the manual(thats where its listed), and that you need GM's operating spec's.<br /><br />This way you've got it from the horses mouth.<br /><br />good luck w/it.

You must be going less than 60 mph to shift into 4 HI. I recently left a Chevy dealership after a few years of working there.<br /><br />If you have push button 4wd (instead of the floor shift) it will not engage until you are going less than 60. If you feel the need to shift into 4 HI anywhere near 60 you might want to re-evaluate your driving! But... yes you can drive up to and above 60 in 4 HI but not on dry ground.<br /><br />My absolute best advice is to read the owners manual.<br /><br />Bob

I live outside of Wash, DC and drive on the Capital beltway daily. Around here if you aren't driving 70+ you WILL get run over! I have found myself shifting into 4 high on the way to work cause it was raining. Then noticed I was driving 75 mph? It's not hard to do with many clueless individuals on the road. But Never had any trouble with shifting in or out of 4 high.
