running 31's on the old girl with a 383/th350 wasn't sure about if i had to change the spline at the end of the shaft and its just a 2WD guess i will start looking around thanks

So i was going thru the old sticker rpo sticker in the glove box and found out that my truck is running on a 3.08 rear end and im sure its the 10 bolt 8.5 i will check in the morning but my question is can i upgrade to say something like 4.10 with out changing out my driveshaft or spline i need something better then the 3.08 for towing a travel trailer

Ok new to the site so hey there boys and girls So i found this site looking for info on towing but nothing is helping so i figured i would ask the smart old guys i have a 88 chevy 1500 its not stock .. running a 383 / th350 with no computer coil over shocks in the back for towing and a trailer hitch rated at i think 6000 lbs so my question is how big of a trailer can i pull loaded i dont feel like pulling anything over 7000 but i need to figure what i can pull rear axle is stock 3.73 i belive
