Steeda Mustang Billet Rear Lower Control Arms - Spherical/Poly Ends (2005-2014)

*Save over 6 lbs. compared to the OE control arms by switching to Steeda!*When only the best will do, say it with billet! These billet rear lower trailing arms replace the stamped steel OE parts, and depending on your desired performance goals are available with urethane bushings or a spherical bearing/urethane bushing combination for high horsepower applications.These lightweight yet super strong arms reduce un-sprung weight and eliminate wheel hop. Steeda was first to market with these control arms and had them on the shelves even before the 2005+ Mustang was released thanks to our exclusive technology transfer program with Ford Motor Company. Steeda was the first to incorporate the proper design rear offset for the rear lower trailing arms.Don't be fooled by other companies claiming to be first with this offset, yet they have only had their arms on the market a few months! Steeda's exclusive polyurethane bushing package also ensures smooth, quiet operation combined with performance. No increase in NVH (noise, vibration, harshness) with our poly bushings like competitors arms. Part number 555-4406 with a spherical bearing on one end and our exclusive poly bushings on the other is recommended for high horsepower applications and will only have a slight increase in NVH over the standard polyurethane bushing arms.Don't settle for anything less than Steeda original innovation.Note: 555-4406 recommended for 500+ horsepower applications. Slight increase in NVH will result from this part.PATENT NO.: US D543,492Learn the differences in Steeda brand control arms, read our blog post for more info: https://www.steedablog.com/2012/01/the-hidden-difference-in-control-arms/ Product BenefitsEliminates wheel hop, improves traction.Super strong billet construction.Lighter than stock and competitors arms - reduced unsprung weight.Used on the fastest production built Mustangs
