BNIB Crank Pulley (Harmonic Balancer)
 

I meant to order one for the 2J but accidentally ordered for the V8 :egads:

Part# 13407-50020

Still brand new, never used. Asking $200 shipped

NOTE: This works for the ALL SC400/430 and GS400/430 and LS400/430

What is it claimed to do? Is it really a TRD part? Link?

It doesn't claim to do anything, Its a replacement part. Its the main pulley that connected to the crank shaft that runs the rest of your pulleys. After time the rubber in the pulley can get hard and fail (like the photo below). If this happens while driving ,its really bad news.

I did a engine swap on my car and I ordered the new one but they sent me one for the V8 and not for the 2JZ. So I don't really have any use for it

It is a OEM TOYOTA part not TRD

This part goes for $307 at Sewell. This is a great deal
