What you are tuning is not damping response but how much the chassis droops and how readily each wheel stays loaded against the rock as the truck articulates. Too stiff and the tires skip over an obstacle instead of conforming to it; too soft and the chassis sags onto its bump stops, losing ground clearance and articulation just when you need them.\u003c\/p\u003e\u003cp\u003eThese are the standard 1.0mm wire springs supplied in the kit, so fitting them returns the truck to its factory baseline. That makes them the right choice if your originals have sagged, or if you have been experimenting with the optional softer and firmer RFW setting springs and want to get back to a known starting point.\u003c\/p\u003e\u003cp\u003eTwo springs are supplied. These are the 12mm\/64mm size; the 16mm\/76mm size is a separate part.\u003c\/p\u003e","brand":"PowerHobby","offers":[{"title":"Default Title","offer_id":44532761919576,"sku":"KYORF013-1210","price":7.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0567\/0554\/8376\/files\/kyorf013-1210_167c7936-371a-44a2-a706-998d8056fbbe.jpg?v=1786242146","url":"https:\/\/beavertonmilestonehobby.com\/products\/kyosho-rf013-1210-12mm-shock-spring-64mm-2pcs","provider":"Beaverton Milestone Hobby","version":"1.0","type":"link"}
