Hey guys i have a 81 pickup and im running 32" tires right now I want to go bigger and found some nice 38" tires would it be possible to run these or would i hurt the truck? it has a 3" lift and I plan on cutting the fenders and doing a dual transfer case in the future.

Should handle it fine as long as you are geared correctly and carry spare birfields

I believe so i just got the truck and the only thing I know about the diff is its welded

You need at least 5.29's for 38" tires. Maybe even 5.71's.

I have a 91 on 38s..... I have 4.10s and its almost undriveable in 2wd high.. You need 5.29s if u plan on hitting the streets.... IMO

THE TRUCK IS NEVER GOING TO SEE THE STREETS JUST THE DIRT. SO WHAT WILL I HAVE TO DO TO MAKE IT DRIVABLE OFF ROAD. THE FASTEST I WILL BE GOING IN THE TRUCK IS 35MPH

Oh well in that case I would go with dana 60s front and rear, an LS1, triple cases and full hydro!

or uhhh what kinda wheeling do you do? mud? rocks? trails? desert? jungle?

There's your guy

I wouldn't trust anybody else to set up 5.71s!

Monster Yota · « **Reply #14 on:** Aug 08, 2008, 02:29:42 PM »

I have 5.29s and run 38.5s all the time, I have plenty of power and with Duel cases I have plenty of low range as well...

Gear swaps are best left to pro's it requires special tools and quite a bit of know how, or yyou will destroy your brand new gears, Marlin sells new gear kits.

5.29s can to. so ive heard. they have been fine with my 35s though

Hottrod81 · « **Reply #21 on:** Aug 11, 2008, 09:12:35 PM »

5.71's will probably work fine if you have an experience person set them up and have the teeth of the ring and pinion set in together more for strength.

Thomas P · « **Reply #22 on:** Aug 11, 2008, 09:56:09 PM »

you could also get them cryo'ed from bobby long, ive been rockin 42"s on genuine gear 5.29''s for a while with no issues.......

I'm running 39.5" Iroks and 5.29's on a fresh 22RE. Pretty slow but it works very well off-road with the dual cases!
