For use with GM LS engine aftermarket Balancers. This heavy-duty, professional tool, equipped with roller a thrust bearing, can also be used as a LS aftermarket balancer puller! The CNC-machined components have a black oxide finish, and are stored in a padded storage case (included) to keep the kit together and organized. The threaded shaft easily threads into the crankshaft, and with the aid of the Roller Thrust Bearing, the drive nut rotates freely for smooth and even pressing/pulling (installing/removing) action on the balancer. The enlarged bearing plate provides a large contact area with pilot studs to keep the harmonic balancer perpendicular with the crankshaft's centerline for bind-free action.

  • Designed as a puller for aftermarket balancers since they have threaded holes. The installer functionality is universal for LS.
