These are decent. Rod ends can rip off on jumps/ hvy springs or crashes as there are no downtravel limiters on the Revo, and the shock ends take it. Had a problem a few years ago and these took care of it. Bit of a pain to get in tho.
In the picture off the link whats the bronze colored washers for ? or are they bump stops ?
I retired from RC, now life is all about guns and long range shooting.
