The Curt Trailer Hitch, # C11762, is a Class I hitch with a 1-1/4 inch receiver. It accepts ball mounts with a 1-1/4 inch shank. With Class I and II trailer hitches, you should use the manufacturer recommended ball mount. This trailer hitch comes with the appropriate ball mount.
For a ball, you can use # A-82 (2 inch diameter) or # A-80 (1-7/8 inch diameter). For trailer wiring on your 2002 Lexus IS300, use Curt Wiring, # C59236. view full answer...
