    How much lift for 38\" tires?

    Hey. I have a '76 K5 that is my "trail use only" vehicle. I'm getting ready to swap the stock TH350 and NP203 for an SM465 and NP205. My question is about tire sizes. I'm going to upgrade to 1-ton axles, and I plan on at least 35" tires. I know a lot of people fit 35" tires with about a 4" lift and some fender trimming. I'm wondering if I can fit 38" or 39" tires with only a 4" to 6" lift and tons of fender trimming. I don't mind hacking up the fenders, and I want the minimum lift needed to fit the tires so it doesn't get too top-heavy.

    Do I need to go bigger than 35"? Are 38's or 39's just overkill?

    Thanks!

    I'm running a 6in. Skyjacker with 36 TSL's and i never rub. Its flex is amazing. When I put it on people told me that the 36's looked too small- if that tells you how much clearance I have between the tires and wheelwell. To answer your question- you can fit 38's with a 6in lift and not too much trimming.

    To answer your question in a nut-shell... yes. If you are only using the truck for trail, why worry about fenders? Sawzall to the rescue. I am running 38's with 4" and plan on running 44's someday with no additional lift. If you wheel hard and off camber, the last thing you need is more lift. I would go with at least 36" tires preferably 38's if you wheel in the rocks at all. A 14 bolt is really low to the ground with 35's. Good luck!

    Check out the webpage "Contagious Racing Online" (I forget the exact url). There is guy with 38" radial Swampers and 6" lift on a Chevy truck that uses it off-road. It might give you a better idea of the fit.

    I couldn't agree more RockBlazer, I run 36x12.5 16" radial swampers with a 4" lift and minor fender trimming for the same reasons. No point in lifting more than you need.

    Just looking at your pic of Urban Assault and thinking of the debate over the low hanging 14-bolt. How much clearance do you have under the lowest part of your diff with 36" tires or have you ever measured it?

    Thanks

    Yeah, I would like to know how much clearance there is also. I would also like to compare it to my 10-bolt and 35's.

    I will measure tonight along with the front Dana 44 for comparison. I know it is more than 3" [​IMG]

    OK
    Just crawled out from under the Blazer, There is 9-1/2" of clearance under the 14-bolt and 11-1/4" under the Dana 44. Anyone with a 10-bolt and 33's? just curious

    Okay I have a Land Cruiser with a Dana 60 in the rear with BFG 35" tires on 15x10 rims and the Clearance under the Dana 60 is 10". I thought some people would like to know.
