It appears I have 'standard' items fitted (whatever the fuck that means once you start googling).

Got the bottom end exposed so i'm thinking of replacing the big ends and mains as a matter of course, they've done about 30k since a rebuild many years ago.

Any benefit to fitting 'uprated' items? Have done a bit of reading and the copper/lead items seem to be the best bet as they are more sacrificial than the uprated items and will preserve the crank long term?

 

Hi
Use Mahle Motorsport ones they are the best

 

I believe i had King bearings fitted when mine was rebuilt

 

King bearings are a very good quality and very cheap for what they are I would recommend them
