Review on 🚗 Dorman 521-970 Suspension Control Arm: Improved Performance for Select Models by Patrick Lets

This part works as intended on my 2003 Tahoe. I swapped out the upper and lower trailing arms and used a Dorman replacement on each. The fresh bushings really helped clean up the rear end and replacing the entire arm is easier and cheaper than replacing the bushings on the arms. If you don't need heavy duty adjustable arms and want an OEM replacement, this is for you. Dorman is as good as OEM or even better.
