Description
If you’re running a Chevy 400 with external balance requirements, this Bert flywheel is engineered to deliver the rotational stability and precision timing your engine demands. The HTD pulley design ensures positive belt engagement for accessory drives, while the one-piece steel construction eliminates harmonics that can compromise performance and longevity. Pair this with your Bert transmission setup for a bolt-together driveline that won’t let you down at the track.
