J&T Bearing's Ultimate Clutch bearings feature's a deeper groove in the bearing races along with a high temperature poly crown to withstand the higher RPM's and high temperatures of today's 1/8 scale clutches. The components of the bearing are protected by no contact metal shields for long life. We are so confident in our Ultimate Clutch Bearings that if they do not out live your current bearings we will sell you some different ones.
*We suggest blowing some of the excess grease out of the bearings with compressed air before installation.
