The truck hub boltsAA-1107-BR, 1108-BR, 1118-AR and 1119-AR have been redesigned and considerably strengthened. This has been accomplished by changing the length of the shoulder and removing the undercut or tapered groove at the end of the shoulder.

Any stock of old style bolts you have on hand should be returned to your Branch for credit and an order placed with them covering your requirements of the new bolts.
