    SFI 29.1 Rated Flexplates

    Built for drag racing yet stronger than OE for street applications, JEGS die-stamped SFI Flexplates use chromoly steel to exceed OE specifications. The ring gear is double welded to prevent separation from the flexplate in high-RPM engines. Each Flexplate is finished with zinc dichromate to prevent degradation & undergoes a final plate inspection to guarantee complete customer satisfaction.

    601071 is rated 4.3 out of 5 by 16.

    Rated 1 out of 5 by from Warped 3/16" out of the box - Returning I bought this and laid it on my granite sink top and noticed it had a decent warp. Thought I'd mount it and see how it goes. Cleaned up crank, cleaned bolt holes, used new ARP bolts - the flexplate wobbles like CRAZY - measured 0.1875" or warping or runout. Junk
