which gears ( Richmond, Motive, ETC.) have the least whine / quietest in a 4.10 ring and pinion and which install kit would you recommend ?

 

Richmonds have a reputation for being loud but I just installed a set of their gearts and their install kit and I can't believe how quiet the thing is, only a faint whine around 60mph. I was very picky about how I set it up though. They stamp each set with the backlash they recommend and I got lucky and was able to nail it. I also had to mess with the pinion shim to get the pattern better.I've heard SLP gears are quiet because they are the same thing as the OEM's.
