Spring - #318 expansion
Spring about 2 1/2" long and 5/8" in diameter used to connect tongue to tongue mount casting in Equinox Trailers built between 1986 and 1990.
The #318 spring connected the center tongue mount to the trailer tongue with two 5/8" x 1 1/2" clevis pins. One through a hole in the tongue mount casting and one through the end of the tongue. A retaining strap was also employed between the left corner of the trailer frame and the bend in the trailer tongue.
