    Check the FAQ,

    Also, in my opinion if you are going to re-gear for a 6 speed 4.88s is where you start to look and although they might be moderately steep for 33s, you have excellent room to grow.

    This is a topic of much debate.
    Take the time to do some searching and reading here.
    For 35s, many prefer 5.13 gears. It may depend on how hilly your area is, or how you plan to off road, plan to pull a trailer, etc.

    Because this is a 6 speed application there isn't as much debate as there is for the automatic. Also, because the initial application is for 33s, 4.88s are going to be at the top of the scale and subsequently with 35s this will be squarely in the wheelhouse.

    I have 5.13's from Northridge in my 6 speed and love them. I thought about 4.88's but I'm glad now that I have 5.13's Although I do have 35's.

    I just pulled the trigger on the 4.88s with a 6speed and 35's I also do alot of towing (Conqueror Camper) and from everything I've read and talked with others who have made the switch it should be right where I need to be, I defiantly wouldnt go with 5.13 with 33's especially with the 6 speed. Just my 2 cents.

    I plan on getting 4.88s with my 6 speed when i do regear, and am running 35s. I plan on eventually upgrading to 37s, even with the 4.88s, it should be fine in the 6 speed. My only debate is whether to sink money in to reinforcing the d30 to bump up to 37s or invest in either a used Rubi axle or a $$$ ProRock 44 $$$. Time and budget will decide I guess

    4.88s might be a bit overkill with 33s, but with 35s, it'll be good. And yea, the 3.21s we get stock just weren't meant to handle 35s

    I have a 6-speed with 4.88's and 33's and I love how it drives. I never have to downshift from 6th on the interstate now and cruising on the back roads is so much nicer. also offroad I can crawl without being in 4-lo all the time, which if you have the 3.21's like I did you know how bad that sucked. I also intend on 35's when these wear out, and I think it will be plenty of gear then also.
