I have a epi9.0 on my 100 series land cruiser. Going by the 1.5x weight rule it's a bit light for my truck. That being said I've never had a problem with it for my heavy ass truck (7k+lbs) and I've never had to use a snatch block to double up on pulling power.
You'll be fine from a power perspective with a 9k winch.
