2001 - 2016 GM Duramax Performance Valve Springs Set of 32
Modern day diesel engines run tighter tolerances, higher RPM's, VGT Turbochargers creating back pressure as well as more boost which can tax the factory valve springs. Aftermarket tuning which may allow more power, more rpm, more pressure may also attribute to valve float causing issues with piston to valve contact. The last thing anyone needs is a failure from this scenario so protect your investment with a set of springs meant to take the abuse.
- Factory specs 71-81 #'S @ 1.610" for INT and EXH
- Springs tested on seat pressure 110Lb @ 1.610" Installed Height
- Rpm Limit of 4K RPM
