Hi i will be stripping my motor down soon to see if my knocking problem is my conrod bearings (most likely)

so i just want to know in advance what are good bearings out there? I rebuilt this motor 30000km ago with KING bearings (never heard of them it what the shop gave me)

I checked all the clearances and were fine with STD size.

so after research the stock nissan bearings seem to be a triple layer arrangement

not sure what these king bearings were

so i am looking for something decent that can take high revs (even though 6000rpm dosnt seem much for an A12??)

I looked in acl catalouge and they only have the duraglide bearing part numbers but nothing in there race series for these motors.

does anyone know a good triple layer bearing?

i service it every 5000km so dirt wont be an issue for a harder type bearing.

if i find something good il most likely change the mains aswell

Thanks!

Nothing wrong with King bearings. I use them in my race engine build.

friend of mine used stock bearings on his race engine. saw 7000 rpm regularly. nothing wrong with the engine. stock bearings are very good too.
