Whoever does the install needs to set them up tight then or they will make some serious noise

thats the only negative thing ive heard from the motive gears is whining noise i wanted the gears from frpp but i didnt want 3.73's and i thought 4.10's may be a little much for the driving i do so went with something in the middle car at the moment when doin 80 it is right at 2k rpms so i dont know what it will be at with a 17in. rim with 275/40 tire

I would run a 4.10 without a doubt.Put them in many daily driven cars with no issues

I installed motive 3.90's in GI Joe's Roush a few years ago. I don't recall a whining noise when we went for the test drive though. Also installed some motive 3.73's in mid 90's chevy truck for a guy I work with. He never mentioned a whine. But yeah on modular fords they bash the motive gears pretty hard about being noise makers

i dont think its the motive gear whining. its the way the 3.90s are cut.
