L5P CSP5 Switch Mounting Bracket
All L5P CSP5 Switches Require This Bracket to be Mounted
This is the required adapter bracket for properly mounting a CSP5 switch in any 2017+ L5P Duramax. The L5P under-dash / OBD-II area is different from Cummins and earlier Duramax applications, so the standard CSP5 switch will not mount correctly without this specific bracket.
Key Details
- Designed specifically for L5P trucks so the CSP5 switch installs cleanly and securely (typically next to the OBD-II port)
- Provides the correct mounting geometry and anti-rotation support
- Heat-resistant construction suitable for the high temperatures found inside the cab
- Simple bolt-on installation (some model years may need slightly longer screws)
Fitment
2017–Current Chevrolet Silverado 2500HD / 3500HD & GMC Sierra 2500HD / 3500HD with the L5P Duramax
Required for Fish Tuning CSP5 switches (and compatible SOTF setups) when used on L5P platforms, including HP Tuners 6-position support.
Note: CSP5 switch sold separately. This is the L5P-specific mounting bracket only.
