What to check before ordering
The manufacturer's diagram lists spring arms 90-02-1099 and 90-02-1299 individually. NewRVParts' 90-01-1099 and 90-01-1299 listings are paired spring-bar kits with distinct order numbers, shown below as related options rather than direct links for the individual drawing callouts. The 16K hitch has different bracket and socket parts.
