Street Stock Aftermarket and Stock Frame Changes Tech Bulletin: 4/18/2025 Recently there have been some questions/concerns regarding changes made to the stock and aftermarket frames approved for use in CRUSA Street Stock competition, and the legality of what changes can or cannot be made to those. After reviewing the approved and non-approved changes and speaking with series tech officials, we are releasing the following bulletin to clarify and clear up the concerns about what is or is not allowed, as well as a short “grace period” to have any car that has unapproved changes be corrected. • Aftermarket frames are allowed to make the following changes only: Johnson version 1 frames are allowed to make right side frame rail straight to match newer version Johnson and BRC frames. Right side replacement frame rail must be square or rectangular tubing. No round tubing. Bottom of the replacement tubing must be flush with the bottom of the existing frame so that the bottom of the entire right side is in the same location as the original chassis was. • Stock frames are allowed to make the following changes only: Stock frame may narrow right rear frame rail for tire clearance (inner portion of frame rail must remain in stock location). • The following applies to ALL Frames: All frames may add strengthening gussets to mounting points such as a-frame, trailing arms, etc. All cars, whether built using the stock frame or aftermarket option, the mounting and pickup points MUST REMAIN IN STOCK LOCATIONS according to the rules. Any deviation in the measurements of the pickup points will render the car illegal according to the rules and will be disqualified. The  GCRG Street Stock division is one of the most competitive and exciting racing divisions competing under the CRUSA banner. While the series will shoulder some responsibility in the questions that have arisen, there are instances where manufacturers and teams are making unapproved changes, creating a competitive advantage and causing their cars to fall outside the rules and limitations allowed. We must make the changes and clarifications necessary and public so that everyone knows what is expected, and to remedy any confusion to keep car counts in place and competition on a level playing field. We are taking this very seriously and will be actively checking and assisting tracks in checking to verify that all cars are abiding by the same rules. These clarifications will be strictly enforced beginning May 1st and will be done so going forward. Shock Rule: 1. One shock per corner. Steel bodied, non-adjustable shocks only. Shocks must have solid shaft. No Schrader valve shocks. No piercing valves. Shock valving or gas pressure may not be adjustable at the racetrack. No air shocks. 2. Shock Claim: a. $300 per shock b. Car claiming shock(s) must finish in the top 5 and on the lead lap. Claims must be made to Tech Official within 5 minutes after the checkered flag falls on the feature event. c. No reverse shock claims (cannot claim shocks from car finishing behind you) d. Refusal to allow shocks to be claimed or confiscated by officials will result in driver losing all points and money for that event, and face the following punishment: i. ii. iii.
