i havent found one except a higher price in parts. You still have to regularly maitence those as well. Reason i stuck with stock was because 4 bucks for a new cup with seals, and 4 bucks for a brand new diff case. So for under 20 bucks you can have 2 completly rebuilt diffs that will last gallons. Think about it, you drive about 4-5 tanks on a race day. Practice maybe about 6 tanks. So think of it as once a once you should rebuild your diffs. I always do mine at about the gallon mark. Never have any kind of diff problems. Never lost a race either because of a diff.
