XRAY 2.5mm Pin Ball Differential
Bought these diffs to replace the 2 older style diffs in my XB2 '18s that were in a word junk. These new diffs build like a normal diff, do not require snap ring pliers anymore, are way easier to adjust, and will last much much longer then the old style diff. Would get at best a full 3 race days out of the old ball diffs before they were crunchy as cornflakes. New diffs took 3 straight days of hard abuse in a mod buggy (6.5), and stock with a slipper eliminator, and no crunch, not even the slightest hint of one. Some things to remember, if running the XB2 rear end you must purchase the 2.5mm pin 69mm dogbones, the 67's are too short. If running the dirt conversion, or a style of it running XB4 rear arms, you need the 71mm bones.
