What do the five end-link mounting holes change?\u003c\/h3\u003e\n    \u003cp\u003eThe five mounting positions change the effective lever arm length of the sway bar. Moving the end link closer to the splined pivot generally increases the effective sway bar rate, while moving it farther outward generally softens the effective rate.\u003c\/p\u003e\n\n    \u003ch3\u003e2.

Can these arms be used in a custom sway bar build?\u003c\/h3\u003e\n    \u003cp\u003eYes. The 20\" length, 25-spline center, and five adjustable end-link positions make them useful for universal Antirock systems when the chassis and suspension geometry are properly designed around the arm dimensions.\u003c\/p\u003e\n\n    \u003ch3\u003e4.

Why use fabricated steel sway bar arms?\u003c\/h3\u003e\n    \u003cp\u003eThe laser-cut and welded 3\/8\" steel construction provides a strong, durable arm for demanding off-road use while also giving custom builders multiple mounting positions for tuning and packaging.\u003c\/p\u003e\n  \u003c\/div\u003e\n\u003c\/details\u003e\n\n\u003chr\u003e","brand":"RockJock","offers":[{"title":"Default Title","offer_id":56879409954982,"sku":"RJ-202007-105","price":142.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0693\/8394\/6406\/files\/RJ-202007-105-20in-Antirock-steel-sway-bar-arms-1.jpg?v=1785336275","url":"https:\/\/wideopendesign.com\/products\/rockjock-antirock-20-fabricated-steel-sway-bar-arms-25-spline-pair","provider":"Wide Open Design","version":"1.0","type":"link"}
