I need to upgrade my gears. whats the best for 36s and do i keep the stock 10bolt or get a 12bolt....i got a friend who owns a junkyard told me he'll sell me a 12 bolt for like 150...is it worth it?

if he's truly your friend he will sell you a 14bsf for $150 not a 12bolt
don't wast any money on a 12bolt,go with a 14bsf out of the same style truck and it will bolt in with a conversion ujoint

For 36's, I think 4.88s are perfect.
I wouldn't mess with a 12 bolt, they're not really any stronger than the 10.
