Ask in the Spec-R forum?

RCTech could be a good source

What wheels were these problems occurring on.

Since moving to serrated nuts a couple of years back I haven't had a single problem.

hi i use sorex 28 with jb insert all ready made so don't know make of wheel

It doesn't matter what wheels do you use. I think the material of these driveshafts is not the same with xray's driveshafts (hudy spring steel) and with xray's wheel nuts. In my opinion, don't use aftermarket parts. You can always use the ECS driveshafts.

Yup I had the same problem – and I use XRAY ECS drives . You need serrated nuts but you need to realise there are serrated nuts and serrated nuts. I bought a set from a big brand name and they were hopeless. I proved this by holding two nuts together and turning them against each other; no grip whatsoever.

The best I ever had were from Poland I think and they were orange too but my online shop has been unable to get them for the past year. I am currently using Hot Bodies serrated nuts which come in blue, not as good as orange but acceptable , after the big name failure and so far they have been fine.
