Camburg UCA's Installed

[HB 4X4]

So exactly What Are the REAL benifits of Replacing the UPPER Controls arms ???

Never Heard of anyone bending or busting them .

Being much stronger is one of the benefits, although the newer Toyota UCA's (Such as on 4th gen's) are extremely strong already.

Other benefits are getting your alignment back to proper specs, stabilizing steering/handling, an extra inch of droop if your suspension allows it, and if you don't have wheel spacers, they allow you to run bigger tires (like 33" or larger) which normally rub the stock UCA's.
