I buy the Boca Bearing green seals for my vehicles. They take a ton of abuse, and last for a VERY VERY long time. The stock bearings in my vehicles only last 1/8 to a 10th of what the green seals last, and worth every dollar. It comes out to about $80-$100 for a set per vehicle. The only bearings I will buy from now on.
