Newbie questions

Hey all, As I sandblast my 85 K 20's frame, I am getting closer and closer to having to purchase a lift kit. Here are my questions:
Why are body lifts frowned upon? They seem good to me...They come with all the hardware I need bolt the body to the frame, and an added bonus, it sits higher!

Why are lifted trucks not good for plowing? Somebody said that on here earlier, But I'm wondering why. I have a set of 16.5 x 9.75 AR rims I was going to mount 33-36's on, (not sure what I decide to go with), but I planned on using normal stock tire wheel combo for plowing.

Since I'm damn determined to lift a plow truck ;-) , Does anyone make front helper springs? I'm okay with my my front end being stiff, Its just my front end is sitting a bit low as it is with out the plow, those front leafs are dying!

What determines a rear end? I just replaced the diff. cover gasket since it was leaking, and I counted 14 bolts holding the cover on, but its not a Dana. It appears to be some sort of stock GM axle. Any good? How did some trucks get Danas fron the factory while others like mine didnt? was it an option?

Maybe you guys could help me some how pick a lift kit..
Heres my scenario:
Plan to hit some mild trails, no rock crawling
Have those AR rims, with plans for 33's-36's to mount. (summer wheels)
Do some plowing. (not commercial, mine and a couple others maybe)
has 350 4 BB
Need to know anything else?

Ohh yeah, how do I determine what I have for a tranny? its a Auto lol...:-)

Re: Newbie questions

The 14 bolts you counted means it is a GM Corporate 14 Bolt rearend. These are very strong & desirable. Remember with 16.5 rims you won't have the lip part that helps hold the bead like a 16" rim.

Re: Newbie questions

well, theres nothing wrong with body lifts. the only drawback is you dont actually gain ground clearance b/c the frame stays the same level, but you gain tire clearance. i still cant figure out why people say they are bad. guess maybe its one of those "mines better b/c i spent 5x that much on a suspension lift" ego things, who knows. it will look like the new HD chevys the way the frame hangs down a little bit more than stock. look at the pics of my truck, i dont think it looks terribly bad. anyways - i dont believe GM ever put dana rearends in their trucks, just frontends. they have GM corporate rears (yours being either the 14 semi-floater or 14 full-floater, both are very strong). as for front springs you can get heavy duty ones that have a higher spring rate and wont sag so much with the plow. as far as why not to lift a plow truck, im guessing b/c you would raise the center of gravity and not be able to give the truck the same leverage when plowing, just a guess though.

Re: Newbie questions

What determines a dana? I was told if it has the little mini bolt on hub in the center of the wheel, it was a Dana.
What else determines a Dana?

Re: Newbie questions

also, I have a NP 208 transfer case, I dont see it listed on chuck's page, are they any good? what "np" stand for? I'm thinking "new process" gear....I live about a 1/2 hour away from it!

Re: Newbie questions

well the "mini bolts" on the hub denote the 14 bolt full floating axle. a full floater is an axle in which the carrier does not support the full weight of the axles, only provides them with power. i believe they have an extra set of bearings that allow this to happen. the semi floater has the same c-clip design as normal axles, only it is stronger due to larger carrier and axle shafts. i prob messed up one of the details, in which case im sure someone will correct me but i know im on the right page. as for the NP yes its new process and the 208 is pretty strong, not as strong as the 205 i think but still strong. there are more details about aluminum vs cast iron and shaft vs chain driven that someone else will explain more b/c i dont know a lot about the older tcases
