Default Upgrading rod bolts, should I replace rod bearings??

Im Upgrading to some ARP 2000 rod bolts on my 67k mile LQ4 with a stock bottom end. Is it good practice to replace the rod bearings with a quality set? If so, whats a good brand, pn???

Thanks,
Chris

if there are no problems with them now, I would not replace them.

Agreed, most of the time when you see someone replace their rod bolts they spin a bearing in the next couple thousand miles.

When you change rod bolts, you should have a machine shop resize the big end of the rod to adjust for the different clamping force. Some people get away without doing it, others don't and spin a bearing. What year is your lq4? I've got a set of 05+ rods with arp 2000 bolts already installed & resized........pm me if interested.

Should I just re-use the stockers then? I only removed one cap so far!!


My LQ4 is a late 02(7-02) has the MLS Head Gaskets but still has AIR fittings on the manifolds.

It's a true rare occasion for someone to spin a bearing because of a need to resize a cracked cap rod in our engines due to changing bolts. Of the thousands who do it, there have only been a handful and even they don't KNOW that to be the case.

Yeah, Ive heard that the Katech Rod bolts are the way to go because theyre equal weight and work without resizing the rods. Ive heard of many using the ARP 2000's with no problems, Im not afraid to dig in and replace them.

If It does end up spinning a rod bolt, it equals a little frustration up front, and then a Forged 408 stroker in the future!
