Default Spherical Bearings for Control Arms?

Does anyone make a spherical bearing "kit" for C4 front control arms? I know of a number of suppliers for the C5 and C6 suspension parts, but I can't seem to locate anyone that makes them for the C4s.



I'm grafting the front and rear suspension from a 1986 C4 onto my 1979 C3 and I DO NOT want to run rubber or poly control arm bushings. If I have to, I could make due with delrin but I would prefer spherical bearings.

Not that I've seen, but Global West has the Del-A-Lum bushings and they are excellent!

Thanks. That's my fallback if spherical bearings turn out to not be an option.

There's no need for spherical bearings on the front control arms. They only move around a single axis, and a spherical bearing is specifically made to allow movement around multiple axes. Even custom racing control arms still come with single-axis bushings.

Old thread almost same Question. So, no need for Spherical Bearings but what about Needle Bearings? I used them 40 years ago in my C3, C5 and newer they are available. How did the C4 get skipped ?

I haven't seen any. Needle bearings might be reasonable. But honestly, just get the Global West Del A Lum kit and be done with it. That address every possible concern while still being reasonably priced.
