4.8 LS ENGINE & 5.3L LS engines used in trucks and SUV’s - Harmonic Damper

Our Mistake BUT YOUR LUCKY DAY!

This damper had the part number incorrectly engraved on the red front ring. It says 90031 but is actually a 90034. It fits all 4.8L and 5.3L LS engines used in trucks and SUV’s. Due to the incorrect numbering, this damper is not considered an SFI Spec #18-1 legal damper.
