*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: 555-4407 recommended for 500+ horsepower applications. Slight increase in NVH will result from this part.

U.S. Patent Pending

Product Reviews

Had these installed by Steeda at their Pompano Beach, Fl location and took it straight to the track afterwards. It was amazing how the wheel hop disappeared and the car hooked up 1,000,000% better than it ever did from the factory. There is a slight NVH increase due to the bushings but nothing that would affect the experience of daily driving the vehicle. Highly recommend this for maximum traction on the street or at the track!

Finally got my lower control arms from Steeda installed. I have got a good chance to test them out to grade them on performance. However, one thing did surprise me... How great they look on the car! It's just a hint of "hey, that's not stock" as you catch just a glimpse of the shine of the LCA from between the rubber and the body. Steeda did a great job at making these beefy and it took just under a hour for a friend of mine to get them on the Mustang at the shop he works at.

Massive improvement over OEM and an improvement over the competitors LCA. Really firmed up the suspension and provides great feedback on what the rear is doing. Almost got rid of wheel hop with these LCA's alone. There is a minimal increase in NVH over the OEM LCA's. A great product that is topped off by an even greater technical staff at STEEDA. Frank, Patrick and Rod are all great to deal with and very knowledgeable.
