Overall Assessment

Customers appreciate the confirmed quality of our Speedway parts, highlighting their reliability and durability even after hard use. Many specifically noted that our lower ball joint is well-made and fits perfectly into the factory control arm, marking it as a great stock replacement. Some customers found the joint slightly oversized which might need minor adjustments but, once installed, performs excellently. It seems our Speedway parts outperform competitors, providing superior value for money. To sum up, our product is consistently described as both practical and robust.

Get what you pay for. The "grease" that was in the joint looked like it was dried up and balled up. After greasing with the gun and working it for over an hour it freed up a little.

Affordable, quality replacement part for hobby/street stocks. The specs don't mention that the lower joint is .020 over sized. While oversize is standard in most aftermarket replacement lines (to accommodate sloppy press fits on 25 yr + vehicles), it is usually noted. This was not noted but is over size. If you have stock joints that have never been out of the A arm you'll need to machine or die grind a bit of the arm material prior to installing the joint.
