Dorman Products' Suspension Control Arm and Ball Joint Assembly, (527-513 and 527-514) each provide replacements for OEM components on certain Tesla Model 3 and Y vehicles, one for the upper right control arm and one for the upper left. These assemblies utilize a strong steel ball join housing with a stamped steel arm to avoid cracking and separation from the steering knuckle. Both are also electrostatically coated to prevent corrosion and moisture intrusion, and the ball joint sits in a sealed housing. Both assemblies match the fit of the factory assembly and can fully replace OEM parts.
