Customers appreciate the affordable, well-crafted, strong, and durable ball joint that fits perfectly, even in specific applications like a baby grand race car. It has been noted for its quality, indicating confidence in the manufacturing source. However, there was a minor issue as the product did not come with a boot, which had to be sourced separately. Despite this shortcoming, customers would continue to buy parts from Speedway, as the product's superior features outweigh this inconvenience.

I would definitely buy this again. I was unsure of what the quality would be like compared to some of the other options out there. I was extremely impressed. The ball joint threaded easily into my control arm and is ready to rock and roll with no drama. You will need to pick up a dust boot if you don't already have one. There's a Speedway version of those that are pretty decent quality as well (part #91034006).

Looks to be sourced from Afco, not sure. Very well made, has set up instructions and overall a nice part. I think this may be an older part but hope Speedway carries it moving forward. I think about the only thing that is a -1 star was that it didn't come with a rubber boot. I know it's for racing but still a pain to source and at the time of ordering Speedway was back ordered on the boots. Why does racing imply no boot?

Do you still have to purchase the boot for the ball joint or is this a sealed unit?
