The 1.5mm wire diameter changes natural frequency and wire stress so the spring compresses sooner, helping the rear tires follow rough ground and hold forward drive out of corners.\u003c\/p\u003e\u003cp\u003eRear free length was shortened from 86mm to 83mm to suit the lower shock towers used on the RC8B4.1, with fronts in the same family reduced to 68mm. Rates step in 0.25 coil increments for fine control over rear grip, and both ends of each spring are marked so 1.5D wire is not mixed with 1.6D.\u003c\/p\u003e","brand":"Associated","offers":[{"title":"Default Title","offer_id":56089216647490,"sku":"ASC81664","price":13.59,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0819\/5063\/8402\/files\/81664_md__83084.1725448973.jpg?v=1788542783","url":"https:\/\/www.powerhobby.com\/products\/team-associated-asc81664-rear-springs-3-50lb-in","provider":"PowerHobby","version":"1.0","type":"link"}
