*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.

Product Reviews

i have been Tarmac Road racing on this part for 6 years over 10,000 miles of Extreme use: very strong and does not break! perfect for all applications. only thing is you must lubricate the nolethane end regularly.

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.

Things are awesome! Much lighter and stronger than stock, not too mention they look great!

These weigh half as much as the factory LCA's. Acceleration feel's more controled also.
