The outer race is a little thinner, so far no issues with 1.28 60s and wheels up in 2 &3 but not a lot of street miles I have run cheep Chinese Empi joints but just changed to tighter GKN German ones to get rid of some of the backlash. Drag racing a stick is an exercise in destructive testing............... we will see about durability

The "rock" is the most eastern province of Canada We is my racing buddy and I The bearings are a proprietary design that uses sealed angular contact ball bearing units and spacer as are the stub shafts and flanges. We went in this direction after starting to twist a previous design of 1.249 spline dia. This all fits the OEM bearing housing and works well with AZC rear brakes, we use 1/2 screw in studs on 5 x 4/2 and had Dave do the rotor hats to match however moving out to 5 x 4.75 would be stronger.

I have heard good things about the driveshaft shop etc As has been rightfully pointed out by JM the 1.25'' diameter limits ultimate strength We have developed a soloution to the OEM size that uses wheel bearings with a larger bore size This allows the use of 1.5'' diameter stub shafts and companion flanges for size 21 CV joints ( commonly called 930 joints from the old factory backed racecar that used them) our own setup uses a variation of the 9'' ford 35 spline 3rd member The car that is using this setup is 427 cid turbo with 5 spd and 10.5 x 28 slicks I currently do not market this and it is expensive, however if someone really need this level of strength..............
