If you want better RPMs on the highway, try swapping to a 3.08 rear gear. I'm assuming you don't want to change to an OD tranny.
Just for example, if you're doing 65MPH with your 4.10 gear, you might be doing 3088 RPMs. Changing the rear to 3.08 will drop you to 2320 RPMs at the same speed.
You will notice less power in the lower gears, but that's the trade off for better highway RPMs.
