Tech Bulletin: USRA Limited Mods

January 17, 2020

On January 17, officials from the United States Racing Association made an amendment to the 2020 USRA Limited Mod rules similar to the adjustment for USRA B-Mods on January 9.

In Rule 13.6.8, Dart Part No. 10024360 and World Products Part No. 043600 were added to list of approved aftermarket GM heads for the USRA Limited Mod class.

These additions are due to the unavailability of the approved EQ head and to also offer drivers an option that is not pre-stamped for use in a different sanctioning organization.
