[QUOTE="squeak12, post: 750181, member: 12742"] I haven't done a ton of full size stuff other than what was provided for me to work with. Installed a lot of Yukons in high HP rigs that didn't explode, but we also set them up solely for rock bouncing with super tight backlash that would likely be unreasonable for a daily driver or possibly even a heavily used trail rig driven at moderate speeds that get the gears too hot. We were also using 14B or Dana 80's exclusively which both will be able to control pinion deflection better than a D60 could ever do which comes back to the good set up part. Sometimes, you are going to be limited to what you are working with in which case cryo and micropolish is your only chance at making a bad situation better. Some claim up to 25% greater strength after treatment. I look at Ultra4 cars and what they are using personally. That being said my recommendation would be Gearworks, but it seems they only make gears for the Ford 9" platform or scaled up to the 10" custom applications. I have a instinctive sense that Yukon or Nitro will be your best direction with a secondary cryo and micropolish treatment to gain strength and reduce heat which would allow you to set the gears up a little tighter than recommended possibly. Just consider that the cheapest option will likely be the cheapest for a reason and some of the higher end options may be priced a little excessively to cater to their market. At the end of the day, only you can decide your budget and how hard you push the skinny pedal, though. If you can't justify the parts due to pricing, the only other option is to tear down and inspect the gears on a schedule that will prevent catastrophic failure and allow you to address excessive wear as you see it.
