Installing Dr. Diff 11.7" Rear Discs on an S60

If I'm not mistaken just about everyone's rear disc kit requires green style bearings. Adjusters can't be used. And....on my Strange super 60 I had to cut the axle retainer off to slide the backing plate on which acts as the axle retainer

DoctorDiff’s rear disk kits can be used with tapered bearings and adjusters.

Many of the rear disk kits do require green bearings, but there are some (like the DoctorDiff 10.7" and 11.7" kits) that do work with the factory bearings. Which is why it’s better not to cheap out on some of the more generic rear disk kits.

DoctorDiff also sells heavy duty adjusters
