My LST XXL CVD's, and Mugen 17mm hex's got here today, Here is a picture of the LST XXL CVD's next to the old MIP CVD's. The LST XXL cvd's are much beefier and should take a much better beating without popping out. To use them in stock knuckles you will need to bore the outside bearing hole to accept a 8x16 bearing, And on the inside you have to use a 15x21 bearing which is a snug fit, But I don't have to worry about it since I am using RD racing hub's which use 8mm outter bearing's. Comments are appreciated.
