How to lift front end of 09 ford ranger 4x4?

So I have an 09 ford ranger 4x4. I leveled the front out by cranking the torsion bars and replaced the shocks. I know want to get a couple more inches of lift so I was going to replace the leafs,
but how do I go about lifting the front?

Use a jack under the main cross member and then wheel stands to make it secure.
