Motive Gears or Richmonds and yes I hear it can be difficult installing
gears I know alot of people who jack there rears by a bad gear install
but if youre experienced or know a good shop that is you should be good

If you have never done it then make sure you either have someone experienced help you or take it to a shop. It's critical that it be done right you will ruin the new gears. I hear motive's are the quietest ones.

my buddy I work with use to work at a differential shop and put mine in. Had it done in 2 hours. I would Highly suggest haveing them done buy someone who has done it before.
As for brand, I have motive. I would suggest Motive performance or precision or yukon they are the best and the brands my buddy recomended. I would NOT recomend richmond they are noisy and the 1 brand my buddy told me to avoid. My motives are quiet but I only have 3.90's.
When you get them done, Pay particular attention to the break in rules. You can use just regular gear oil to break in the gears. Drive for 15 minutes, stop let the rear end cool for at least an hour or 2, do this 3 times to "quench" the gears. Drive easily for 500 miles, Change the gear oil, I would suggest royal purple. Then give her hell.
I would suggest Saveing your money and get a 9" or 12 bolt (preferably a 9") for the $500 (gears, rebuild kit, oil, gasket, labor) you will spend on the gear swap, you'll be 1/4 of the way to a new and 10X better rearend. I wish I would have done this.
I am now saving for the 9".

They are noisy because of the high grade steel, which is stronger. I have Richmond 4:10s with no gear whine at all, because first of all, they are set up correct. Secondly, like you said, break in is very important.

ive always used richmond, and never had any whine, 3.90's 4.10's 4.56's its all in the install and the break in. ive actually heard of people putting there gears in the oven for any given time to help with this.
