This is one I'd say spend the extra $ and get the best, FRPP. Unless you like whiny gears. I have FRPP SVO 4.10s. They cost more than the regular FRPP gears but they are silent and durable.
Some have had good luck with Motive, some with Strange, etc. But I haven't heard ANYONE dissatisfied with FRPP gears. It's not something you want to do twice. I learned the hard, expensive way. Don't make the same mistake. (My Motive 3.90s failed and broke my differential carrier)
I paid $380 for my SVO gears and $380 for installation. Expensive, yes, but I have high confidense in these gears and that is worth something.
