Boy I just scored big!!! I found a 67-72 3/4 ton gmc In a local yard with the H052 axle with 4.10 gears. looks like brand new on the inside & very little slack ( you want some ). All I'll have to do is replace the pinion seal & I'm good to go. this is going to be a really big improvement in my 50 3800. now that i have my broken speedo needle fixed & cable greased i realize i was going alot faster than i thought i was! now that i actually know that i'm going 50-55 it isn't near as loud. the 4.10s will be way better than the 5.14s going down the road & i'll still be able to pull anything i want too. robert
just got it put in today. Man what a difference! like driving another truck almost. I'm running about 2400 @ 55 with 32" tall 750-17 tires. the 8r19.5s (33") I'm going to will drop it another 75 or so rpm. if you've got a 1 ton with 5.14 gears I highly reccomend this swap. Robert

of course it is. there are ways to adress this, adapters & such. when I said what rpm i was turning at a given speed i wasn't saying what the speedo actually read. when it says 45 i'm actually doing about 60. check this out: http://www.oldchevytrucks.biz/47_55/full.asp?page=162
beautiful truck! If you haven't done it already put some sway bars on it, you'll love the way it handles. check out my pictures for the install on my truck. I used cpp's sway bar on the front & a front sway bar from a ford explorer in the back. pretty simple job and it didn't do any permanent harm to the truck's originality. even the crossmember I welded on the back could easily be cut off & ground smooth.
