Show original supplier description

The ATI Super Damper harmonic crankshaft pulley is a direct replacement for the OEM unit on B58 Supra GR models, available in both a stock size (918573) and a 21% underdriven version (918351). Constructed with an aluminum shell and a steel hub, this damper is built for durability and performance. It features laser-etched timing marks for precise installation and a black zinc chromate finish to resist rust. The damper exceeds SFI 18.1 Safety Certification, making it suitable for competition use. Fitment is specifically for the 2020+ Toyota Supra GR (A90, A91, MKV, MK5) models equipped with the B58 3.0L engine. The pulley has a 7.074" diameter and a 3-ring inertia weight of 2.20 lbs.
