[Fot] Maxpeedingrods

[Phil Gott]

Thanks everyone!
Good advice! Buy them, have the big ends checked for roundness and small end sized for the wrist pins I will install and then use them.
Regards,
Phil

Most production rods are honed and thats good enough for most applications, but not if you are chasing perfection. Also, hand honing on a machine designed for general applications like brake cylinders etc , can be a disaster as they can looks good, but actually be barrel shaped

>> yes, we used quite a few sets in our engine shop for high HP jap engines, never triumph. quality seems reasonable. the only on-going issue we found with cheap chinese rods like this is the big end tunnel is imperfectly honed. it was not uncommon to have to re-size them. in fact we did a few hundred for one importer at one time. we were never able to confirm if the bolts were really ARP, or just copies

They will provide steel specs if asked. They have some real oddities , like 1mm longer or shorter for various applications, so its obvious they make for performance applications, not just replacement for mom and dad shopping carts
