Overall Assessment

Customers generally commend the product's strong qualities, including good fitment and quality. Many customers have successfully used it as a direct factory replacement of the upper control arm, indicating its practicality. Besides, customers appreciate that it matched the stock part perfectly, underscoring its usability. However, one customer has expressed dissatisfaction due to the need for lubrication after installation. Another customer was disappointed with the product's longevity, as their part only lasted 10,000 miles. Regardless, the majority are inclined to repurchase and would recommend it over competitors.

Oh Yeah

I installed this control arm on my 1976 Mustang II, and it fit perfectly without any modifications. The construction is sturdy, the welds are clean, and the bushings feel high quality. Handling improved noticeably, and the car feels more stable on the road. The black finish also looks sharp and durable. The only small downside is that it's slightly heavier than my old OEM arm, but that just adds to its strength. Overall, an excellent replacement part.

I would not buy this product again.

At first they looked to be a good product but once I had them installed it was obvious they were assembled dry with no lubrication. So now I have a really nice looking 34 Ford that sounds like it's falling apart.

Just received Mustang ll upper control arms with poly bushings and ball joints assembled. Grease zerk is included too but, the ballpoint rubber sleeve (cover) is free and seemingly not able to seal enough to hold grease. Will it seal once the ball joint is tied into the knuckle? Thanks
