What is the best deal for a good rear 9.25 install kit ?

 

I recommend Yukon or Mopar install kits, USA standard is cheaper but they use Koyo bearings and races. I recently pulled apart one of the new ram 1 tons with koyos and found that they had spun in the seat and it wasn't due to lack of lubrication.

 

Use Timkin bearings! Just get one that uses quality parts.
