Overall Assessment

Customers found the control arms to be a top quality and practical solution, saving them time and frustration in their projects. They were praised for their excellent, factory-like fit and finish, along with the inclusion of features like poly bushings and ball joints. Users remarked that the control arms made their rides tighter and nicer, while also making their projects easier, particularly due to their good welds and construction. Some experienced issues with loose bushings and poor paint job, but found that replacements were processed effectively. Overall, customers would recommend and buy these control arms again due to their fit, usability, and quality improvements to their rides.

Good Value, But ...

In my experience all the parts were there but not assembled correctly. My upper arms could barely be forced to rotate on shafts & in doing so creaked & squeeked to no end. Assemblies were bone dry. Had to remove from vehice, completely disassemble crossshaft, remove paint from inner sleeve, smooth welds on outer sleeve ID & lubricate (silicone grease) the poly & all the associated pieces. Afterward they worked fine. Definitely not Plug n' Play.

I ordered all new bushings and ball joints to replace in the original control arms. After all the work removing the factory rivets, I found the ball joints didn't fit in correctly. I skipped it for a bit so I could work on the bushing. The previous owner had welded the bushing housings into the arms. After hours of work I decided to order new control arms and found these. What a time saver.
