Atomic Billet Flexplate Kit – Ford Barra DOHC | 9mm Chromoly | ARP Bolts + Nord-Lock Washers | SFI Certified
Description:
In high-horsepower Barra builds, the factory sheetmetal flexplate becomes a serious liability. Over 1000+ horsepower is often channeled through a 2mm stamped plate to move a car weighing 1800kg+, putting enormous torsional loads on a part that was never meant to handle that kind of abuse.
The Atomic Billet Flexplate Kit is engineered to solve this problem once and for all. CNC-machined from EN26 chromoly bar stock, this 9mm thick billet flexplate is over 4x stronger than OEM, features dual bolt patterns, and is SFI 29.1 certified for competition use. Designed to exceed ANDRA requirements, it’s the same plate used in Atomic’s most powerful street and drag builds.
This kit includes premium ARP flexplate bolts, Nord-Lock locking washers, Unbrako fasteners, and high-tensile torque converter bolts — ensuring your driveline stays locked down under extreme power and shock loading.
