Hi, im realtively new here and was wondering if i could get some help

I recently put an exhaust brake on my 1st generation 5.9L cummins and need to locate a place to find stiffer valve springs, any suggestions would be appreciated.

 

Any Cummins Dealer. Use genuine parts, not junk. Cummins part number - 3916691. This may help too, it's in the sticky at the top>> https://www.dieseltruckresource.com/...d.php?t=171288

 

Also fill in your signature with the some info about your truck model, etc. etc. That way you will get better answers.

This is a great forum.

Later, Tony

 

thanks a bunch for the help
