Small balljoints (4.3mm, steel) Yokomo with RPM cups. Balljoints again come in a large assortment of threads, shoulders, necks, etc. Plus they come in titanium as well. Original Yokomo cups are good too, but have a little bit of play in this combo. Where space is a problem, these may be used as they are significantly smaller than the RPM item.

Other than where mentioned above, these combinations are very smooth and have no play at all whatsoever and have a rather long life. I have never had one pop in a crash either but this may be a problem if you'd rather one popped out than break something else. I usually break the hub carrier. That's OK by me to snap a hub carrier,instead of another part thats more of a PITA to change.The other option for those willing to accept the breakeage (sp) is the captured ballends by Rocket City but they are way fatter,available in 4-40,6-40 thread sizes. I broke one,once.Dubro #2317 is a brutally strong ball link replacement.They come with brass "balls",a little heavy.An RPM substitute would be the 1/4" Delrin balls #73181.Hard to find!(Losi lower shock balls). On my T-4,they are the best for the outer REAR camber links and the front steering arm ends. Then,you will snap the bell cranks!!!! My 2 cents. Dave in Seattle.

Good luck finding these.
