Wrist pin bearings
When I received the bearing it was missing 2 needle bearings. RM was great about lt and immediately got another one in the mail. Check all your parts before installing. Nice to know RM stands behind there products.
Gave 4 stars because I do not have a lot of hours on the bearing.

Perfect OE fit. Good price value.
OE fit. Good looking quality.
No performance gain with a replacement needle roller bearing.
Durability should be better than OE.
Have not fired up the re-build yet.

Is this the big end wristpin bearing?
A shopper on Nov 28, 2016
BEST ANSWER: There's only one wristpin bearing on a connecting rod and that is where the piston and the connecting rod join. This is that bearing.
Can I use my Wiseco wrist pin bearing on the ProX Piston?
Julio M on Sep 3, 2018
BEST ANSWER: Yes, you should be able to as long as your connecting rod/crankshaft assembly is stock size.
