Has anyone put 37s on a 2nd gen with 3.55 gears of I really have to I’ll put 4.88s in to get more low end I do lots of off-roading no rock bouncing just sand and swamp my tranny is getting upgraded so that will be fine I’m going to probably put on headers and better exhaust down the road but not building a power house anytime soon engine only has 120k on it so I could put some top end performance and not worry about bottom end cause it’s still a young 5.2l so people with 37s chime in even if you have re geared I wanna know how it is but also I wanna know how it is with 3.55s most importantly

 

You really want to re-gear for 37's. I think 4.88 is as high as you can go on a 1500...... The 3.55's would make life really tough on your trans with the large tires..... Gonna need some lift, or, some body carving to fit 'em as well.

 

I have 40s on 1500 axles with 3.55 gears

 

well how does it drive like I really don’t care about slow my other dd is a 4 banger Jeep on 35s that sits over gvwr parked and I know 4 low won’t care about 37s will the truck get on the hwy and will get to 4th so I don’t burn out clutches on long trips and yes I’ll use my gps to not speed which where I am is like 80 and up is speeding.

 

i got 8 inches of lift so no trimming right I’d hate to mess with the fenders I like how they look and the guy I got it from took fender liners out so I guess it has a bit more clearance idk

 

Still gets to 4th. Harder to accelerate but it's not that bad in my opinion. Just be warned the 1500 shoes have a max tire size of 35s before you start bending C's and breaking axles

 

so I’m guessing I should beef up the 44 a bit and the 9.25 should be fine it’s basically a d60 right

 

No both axles are weak. I only have those access because I had to find the factory 2500 axles. The time you spent beefing up the 44 and 9.25 you are better off swapping in Dana 60s. The 9.25 is very weak compared to the 44 as it's a c clip axle.

 

okay so 2500 axles bolt up

 

Front yes the back you have to weld your spring perches off of the 9.25 onto the 2500 axles
