    I've always run longbed trucks. Now i've got a 1990 k5 blazer and i want to lift it. I was just wondering how high i can safeley go without the need for a modified shafts. I have a 4" skyjacker to go under it, but I'd like to go more(as in adding more springs or blocks) and as a side note it sits the same as stock and has no sag to it now.

    Typically you can go 4" block or spring and not have to do any driveshaft mods. This however is only a starting point, the only true way to tell is lift it then see if it will still work.

    my 83 blazer w/ 6" procomp lift and 35" tires needed no driveshaft mods. and still drives and wheels fine, but a cv or fixed TC yoke would help.

    i was running 8" lift with stock front shaft and had the rear lengthened 3" and it worked fine. 6" lift would be the most id run if you dont want to do driveshaft mods.

    I have an '83 K-5 with a 6 inch Rancho lift and 35in Mudders and the drive shaft has fallen out of it once already. Luckily I carey enough tools and spare fluids to put it back in. My slip yoke is hanging out pretty far and I am currently saving up to get a custon shaft made at the local axel and driveshaft shop.

    in the grand scheme of things, driveshaft mods aren't all that expensive. i wouldn't let that hold you back from drving the truck with the stance you want to. IMO

    alright thanx guys, i think I'm gonna stick with a 4" for reliability, and the fact that i only got a set of 33" bfg muds for the winter. My truck gets all the goodies put on it, the blazer is just a little beater/daily driver, I also got front and rear hitches, and a brushgaurd so I'll post pis when I'm done

    Damn stick a set of white wheels on her and take the running boards off and you have a carbon copy of my truck. As well as the same driveshaft issues
