strength by allowing the use of larger diameter axle shafts capable of handling higher torque loads and extreme traction conditions. However, larger shafts also place additional stress on wheel bearings and spindle components, making bearing quality and preload control critical.\u003c\/p\u003e\n\u003cp class=\"p1\"\u003eThis system uses Timken bearings combined with precision spacers and retaining hardware to help maintain proper bearing preload and lubrication under heavy load. Proper wheel end support is especially important in rock bouncing and competition environments where repeated shock loading can quickly damage undersized or improperly supported bearing assemblies.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003chr\u003e","brand":"Crane Axle","offers":[{"title":"Default Title","offer_id":56095459377318,"sku":"CA01030","price":449.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0693\/8394\/6406\/files\/CA01030-40-Spline-Spindle-Wheel-Bearing-Set-1.jpg?v=1777413719","url":"https:\/\/wideopendesign.com\/products\/40-spline-spindle-wheel-bearing-set","provider":"Wide Open Design","version":"1.0","type":"link"}
