Like all RPM products, these rod ends are guaranteed by RPM not to break!

Purchased these after I had my stock turnbuckles coming out of the rod ends. I also purchased the titanium turnbuckles at the same time. I have not had a problem since upgrading. Almost lost a dog bone on the track from the stock ones falling off so much. Definitely a great purchase if you are having the same problems I was!

Love them ,got them in blue ,yellow and purple for my 3 -SC10.2's .this is how I identify them on my transmitter. When new they are hard to adjust with out them popping off . I only wish they came pre threaded for easier installation. I believe since it's so hard to thread it on that it makes them nearly impossible to strip out ! I won't use any other brand !

I now have the long shank ball cups. Great because you can easily shorten them to suit the vehicle.

these are just beast! Ive had the stock ones rip right off time and time again. Also the stock ones lose their thread easy I think. IMO these are the way to go and their really cheap so why not?

These are really good!!! Had these on my rc10t4.1 for 1 1/2 years. No problems. I would highly recommend this product and if the break just take your receipt and send them back and you can get a new pair. RPM has a lifetime warranty

Not happy, had them pop off on 2 A-mains for Australian nationals.
Checked all possible causes, none found. Replaced with same (brand new) and with brand new titanium ball studs...still happened. A team mate gave me some ivory white rod ends...these ones held on and i finished the 3rd A-main final.

awesome stuff!!!! I think they are a little bit overkill and that the color is tacky but otherwise great.
