What to check before ordering
The 16K hitch uses head 90-02-1600, sockets 90-03-1600, L-brackets 90-02-5116 and single spring arm 90-02-1699. The related product 90-01-1699 is a distinct paired spring-bar kit, not the individual diagram MPN. Do not replace a 16K L-bracket with 90-02-5150 intended for the smaller hitch family.
