When the car leans  (i.e., rolls) in a turn, one side of the chassis moves upward relative  to the rear axle, the other side moves downward, and the upper control  arm must twist (rotate) to allow for the axle to articulate through its  suspension travel. This rotation causes the control arm bushing to bind.  If this bind becomes excessive, it will raise the rear wheel rate and  produce sudden, uncontrolled, undesirable changes in handling (e.g.,  snap oversteer).\u003c\/p\u003e\u003cp\u003eFord minimizes this suspension bind by using compliant rubber  bushings in the upper control arm. This very \"soft\" bushings help  accommodate the necessary motion of the control arms during body roll.  However, the rubber bushing does not provide much in the way of forward  and aft support, which can cause wheel hop during hard acceleration and  braking.\u003c\/p\u003e\u003cp\u003eIt has become common practice to replace the stock rubber control arm  bushings with solid or two piece polyurethane bushings to resolve the  shortcomings of the soft rubber bushings. Hard polyurethane bushings  eliminate wheel hop, reduce axle deflection, and improves straight line  grip. However, the downside of common aftermarket bushings such as  delrin, steel, stiffer rubber, solid or two piece polyurethane bushings  is they prevent the necessary movement of the control arm during body  roll, which in turn produces significant binding in the suspension when  the vehicle is cornering. The polyurethane bushings also place  unnecessary high stresses on the upper torque box mount, which is the  attachment point for the control arm to the chassis. Standard  aftermarket control arms do not allow for rotation of the control arm  during cornering because of the stiffness of the bushings.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e The Solution:\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eJ\u0026amp;M Products designed and built a tubular upper control arm which  will eliminate the unwanted uncontrolled control arm flex. Round tubing  is harder to work with but has many other advantages over square or  rectangular tubing. It is stronger in bending, torsion, and also lighter  than square or rectangular tubing.\u003c\/p\u003e\u003cp\u003eJ\u0026amp;M Products then solved the shortcomings of the factory rubber  and other aftermarket polyurethane and stiffer rubber bushings. J\u0026amp;M  Products accomplished this with their Patent Pending 3 piece Poly-Ball  bushing combination. By spending countless hours looking and dissecting  the geometry and the need of the rear suspension they have come out with  bind-free bushings set up. J\u0026amp;M Products incorporates a very hard  inner polyurethane ball which is surrounded by soft socket outer cups.  This combination allows the bushing to articulate like a spherical  bearing during cornering but the hard inner ball does not allow the  bushing to deflect during acceleration giving you great traction during  acceleration like solid bushings but remains completely bind free during  cornering for great predictable traction in the corners.\u003c\/p\u003e\u003cp\u003e· Reduces wheel hop \u0026amp; improves traction by eliminating control arm flex!\u003c\/p\u003e\u003cp\u003e· Rugged 1\"-14 threaded bungs and adjuster for added strength over convential 3\/4\" threads\u003c\/p\u003e\u003cp\u003e· Custom made pinion snubbers for a proper fit and finish\u003c\/p\u003e\u003cp\u003e· Durable black or red powder coated finish\u003c\/p\u003e\u003cp\u003e· One piece saddle axle housing mount for a stronger design\u003c\/p\u003e\u003cp\u003e· On Car Double Adjustable for easy adjustment\u003c\/p\u003e\u003cp\u003eFits:  2005, 2006, 2007, 2008, 2009, 2010 Ford Mustangs\u003c\/p\u003e","brand":"JM Products","offers":[{"title":"Default Title","offer_id":48141321273602,"sku":"JM-23985B","price":154.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0787\/0618\/0354\/files\/jm-23985b.jpg?v=1784983473","url":"https:\/\/www.lethalperformance.com\/products\/j-m-05-2010-mustang-double-adjustable-upper-control-arm-street-performance-black","provider":"Lethal Performance","version":"1.0","type":"link"}
