Overview

It is built for builds that run a serpentine belt but need an SFI approved damper. The engine family is named two ways, so verify before buying.

Owners of GM small blocks with an internal-balance crank who need an SFI rated serpentine damper. Anyone unsure whether their engine is LS1 or LT should check the part number.
Pros and cons

Performance notes
A balancer removes torsional vibration from the crank, and internal balance means no extra weight is added to the damper. The serpentine face carries the accessory belt.
