Trailers with a 1\/2\" hole will require enlarging the hole to accept the included 9\/16\" bolts. Always verify bolt diameter before installation to avoid improper fit or damage.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eIncludes two 9\/16\" bolts and two matching 9\/16\" nuts.\u003c\/li\u003e\n  \u003cli\u003eDesigned for EZ Loader trailers that specify 9\/16\" hardware.\u003c\/li\u003e\n  \u003cli\u003e1\/2\" bolt holes must be drilled to 9\/16\" to install these components.\u003c\/li\u003e\n  \u003cli\u003eTwo complete sets provided—enough for one spring perch or paired sides.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat are the bushing materials and sizes?\u003c\/h3\u003e\n\u003cp\u003eThe kit pairs nylon and steel bushings so you get resilient spacing plus a hardened inside sleeve for the bolt.
