Upgrade your MRC cage kit with our Double Frame Rail Section, or add a transmission tunnel to your stock firewall setup for increased drivetrain clearance and a cleaner finished installation.
This add-on was developed to integrate with our existing MRC systems while still allowing flexibility for custom builds and real-world installation variances.
All tubing is supplied un-notched to allow proper fitment based on your exact chassis dimensions, mounting locations, drivetrain placement, and installer preferences. Every build varies slightly, and leaving the tubes unfinished ensures the best possible final fit.
For customers using the stock firewall tunnel option, we’ve included reference photos of the same style setup currently installed in our MRC Shop Car. This option allows you to retain the factory firewall appearance while gaining additional transmission and driveline clearance where needed.
Please note:
-
Tubes shown in red are NOT included and are shown for reference only.
-
Mid plate is supplied un-bent to the stock firewall to account for installation differences and allow proper fitment during assembly.
-
Designed to pair directly with an existing MRC kit.
-
If installing as a standalone component or using with a non-MRC setup, please call before ordering so we can verify compatibility and ensure you receive the correct components.
Built with the same approach as our race-proven shop chassis—giving you the flexibility to fit it right the first time.
NO RETURNS/REFUNDS/CANCELLATIONS FOR ANY REASON. PLEASE CALL PRIOR TO ORDERING IF YOU HAVE ANY QUESTIONS.
