MMR S550 Mustang Adjustable Sway Bar End Link Kit (FRONT & REAR)

The MMR S550 Mustang FRONT and REAR Adjustable Sway Bar End Link Kit is the best and strongest on the market. Why? Our kit features true Ball Joints not noisy heims joint like Cortex. Our kit features TRUE 12mm adjustment ends not a mix of 12mm/10mm Like Whiteline. Our kit features 4130 Chromoly Ball Joints, not standard lower strength steel like the ALL the other brands. What does this mean? A stronger, Better Product and a Difference that you can feel and thankfully wont hear!! 

Due to the weak factory links that bend and flex this kit from MMR will provide Noticeable increased corner grip and steering response along with decreased lap times!!!
