A crownlock nut helps reduce that risk by keeping steady thread pressure on the bolt.\u003c\/p\u003e\n\u003cp\u003eFor best results, replace worn or repeatedly removed crownlock nuts during service, especially on pivot bolts, suspension, roller, bracket, and frame hardware.\u003c\/p\u003e\n\u003ch3\u003eImportant Difference: 5\/8\"-11 vs. 5\/8\"-18\u003c\/h3\u003e\n\u003cp\u003eThis part is a \u003cstrong\u003e5\/8\"-11 coarse-thread crownlock nut\u003c\/strong\u003e.

The key difference is how the wheel is fastened. If your trailer uses a screw-in stud with a separate lug nut, this old body style stud may be the correct replacement. If your trailer uses a hex-head bolt that passes through the wheel and threads into the hub, you likely need a lug bolt instead.\u003c\/p\u003e\n\u003ch2\u003eWhat to Have Ready When You Call\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003eTrailer year, make, and model\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eVIN, if available\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eExisting fastener style: screw-in stud, lug bolt, or press-in stud\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eThread size and stud length\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003ePhotos of the hub, wheel, and existing fastener\u003c\/strong\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EZ Loader","offers":[{"title":"Default Title","offer_id":53048148722029,"sku":"290-028828","price":7.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0966\/3761\/6493\/files\/EZLoader290-028828LugStudScrewInwithdimensions.jpg?v=1774981570"},{"product_id":"ez-loader-spring-equalizer-shackle-tandem-triple-axle-250-031579-10","title":"EZ Loader Spring Equalizer Shackle – Tandem \/ Triple Axle – 250-031579-10","description":"\u003cp\u003e\u003cstrong\u003ePart Name:\u003c\/strong\u003e Spring Equalizer Shackle\u003cbr\u003e\u003cstrong\u003ePart Number:\u003c\/strong\u003e 250-031579-10\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOEM EZ Loader trailer spring equalizer shackle designed for tandem and triple axle trailer suspension systems.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThis galvanized steel component connects the leaf springs to the equalizer, allowing controlled movement and proper load transfer between axles.\u003c\/p\u003e\n\u003ch3\u003eWhy This Part Matters\u003c\/h3\u003e\n\u003cp\u003eThe equalizer shackle plays a critical role in how a multi-axle trailer distributes weight.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eload balancing between axles\u003c\/li\u003e\n\u003cli\u003econtrolled suspension movement\u003c\/li\u003e\n\u003cli\u003ereduced stress on springs and frame\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eWithout proper function, the suspension system can bind, wear unevenly, or transfer load incorrectly.\u003c\/p\u003e\n\u003c!-- 🔽 INSERTED TABLE HERE (BEST LOCATION) --\u003e\n\u003ctable style=\"width: 100%;
