Default Need Help! What Rearend/diff?

I Have An 03 Tahoe With 305/45/22 And It Came With 3.73 Gears. I Went With 4.56 Gears (mainly For Towing But General Driving She Really Moves). I Have Burned Up 2 Sets While Towing.
I Love The Gear Ratio But I Am Being Told The Trailer Is Too Heavy For The Diff. The Stock Gears Never Had A Problem (except 4 Mpg @ 5000 Rpm)
Please Give Me Options On "beefing" Up The Rear End Or Is There A Difference In The Gears From Other Manufacturers?

How much weight are you towing? It sounds like you have way too little of a tow vehicle for the load.

your rear end should be fine for a 5000 lb trailer
