The thinner wire changes the spring's natural frequency and internal stress so it compresses more easily and the rear end conforms to the surface instead of bouncing across it.\u003c\/p\u003e\u003cp\u003eRear free length was shortened from 86mm to 83mm to work with the lower shock towers introduced on the RC8B4.1, matching the fronts that dropped to 68mm. Rates are grouped in tight 0.25 coil steps for fine adjustment of rear grip and forward drive, and both ends of the spring are marked so 1.5D wire is easy to distinguish from 1.6D. Fits 16mm big bore shocks.\u003c\/p\u003e","brand":"Associated","offers":[{"title":"Default Title","offer_id":56089216549186,"sku":"ASC81662","price":13.59,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0819\/5063\/8402\/files\/81662_md__36766.1725448971.jpg?v=1788542781","url":"https:\/\/www.powerhobby.com\/products\/team-associated-asc81662-rear-springs-3-75lb-in","provider":"PowerHobby","version":"1.0","type":"link"}
