The Unified Late Model Rules Alliance (ULRA) has released its Super Late Model rulebook for the 2025 season.

Some ULRA-sanctioned entities include the ASA STARS National Tour, the ASA/CRA Super Series, and the ASA Southern Super Series.

So what exactly has changed?

While the number of changes is relatively small, some of the changes carry rather big implications for Super Late Model competitors. Below you can find all notable changes that will be put in place for 2025.

Eligible Cars and Bodies Guidelines

Rule 1 under Section A: Eligible Cars and Bodies Guidelines has added a provision stating, “All parts must remain as produced unless
otherwise specified.”

This rule as it relates to ABC-approved body rules comes shortly after the announcement that the American Speed Association is spearheading an effort to re-establish the ABC committee.

Engines

Rule 1 under the Sealed & Other Engines subsection of Section B: Engines has added a provision stating, “McGunegill Ford Sealed Engines must compete at 7400 RPM until updated by McGunegill.”

Perhaps the biggest rule change for 2025 sees McGunegill engines subject to a limitation of 7400 RPM as opposed to the 7600 that was allowed last year.

This change comes after an engine dyno test in which Ty Majeski’s McGunegill engine that was found illegal following the 2024 ASA STARS Father’s Day 100 at the Milwaukee Mile.

Minimum Chassis Eligibility Requirements

Rule 4 under the Frame subsection of Section C: Minimum Chassis Eligibility Requirements has added a provision stating, “Rear sub-frame rails must be connected by a cross member of the same size tubing at the point of termination.”

Suspension

A new rule has been added to Section G: Suspension. The new rule, Rule 9, states, “Lower A-arms can have no type of panning between the lower control arm and strut arm.”

Safety

Finally, there have been two new additions to the rulebook under Section L: Safety.

Rule 6 has added shoes as a mandatory part of a driver’s fireproof suit.

Rule 7 has added a provision stating, “Safety net must be a rib-type construction made from 1” x 1” wide material with 1” x 1” square openings when installed. Safety net must not be flush with the body or connect to the body at any point.”
