    Hey all,
    I have a couple of questions about getting gears re-done. I have an 81 K5 with a th350. 12 bolt in back 10 in front. I was wondering if 4.10 would be good for 4" lift and 35's. My truck has a hell of a time trying to go between Phoenix and Flagstaff due to the hills. Before I put the lift on a couple years ago it still had trouble up the hills. I was also wondering if anyone knew of a good shop in AZ for get gears redone. Thanks for the info

    dunno about shops, but 4.10 is a good gear choice for 35s. Its pretty much as low as you can go without OD. I run 35s and 4.56s on-road, but I have a 700r4 (and therefore OD). Anyway, 4.10s should work well for ya,

    <font color="green"> Something that you might look into is swapping the axles to a set from a 3/4 ton. You might not need the added strength, but since 3/4 tons came from the factory with 4.10s sometimes you could pick up a set of axles for under $500 and save yourself some money. You will have to factor in the fact that you'll need new 8 lug rims, but you should still come out ahead. Just another option for you. Also, 1/2 tons that came from the factory with 6 cyl engines had 4.10s most of the time. /forums/images/graemlins/thumb.gif</font>

    DesertDueler (Dan) does gears. He did the gears in my 14bff rear, and also my 10 bolt front. He does good work. PM him. He might get you hook ups on parts too. He is in Chandler also.
