Product Description
CUMMINS 3595658 OEM TURBOCHARGER V-BAND CLAMP – HE341/HE351CW (2003–2007 5.9L)
The genuine CUMMINS 3595658 OEM turbocharger V-band clamp is the correct factory clamp used to secure the turbine outlet on HE341 and HE351CW turbochargers found on 2003–2007 Ram 5.9L Cummins trucks. This clamp locks the turbocharger’s turbine housing to the downpipe connection, maintaining a leak-free, high-pressure exhaust seal essential for spool-up, boost response, and turbo efficiency.
Over time, factory clamps can fatigue, stretch, seize, or lose clamping force—leading to exhaust leaks, whistling, slow spool, or black soot around the turbo outlet. Installing a new genuine Cummins 3595658 restores proper sealing force and reliability. Pair it with authentic Cummins hardware such as the CUMMINS 3919687 turbo oil inlet fitting or other verified components in your turbo system refresh.

Frequently Asked Questions
WILL THIS FIT MY 2003–2007 5.9L CUMMINS?
Yes—if your truck uses the factory HE341 or HE351CW turbocharger. Always verify by VIN/ESN if uncertain.
SHOULD I REPLACE THE V-BAND CLAMP WHEN INSTALLING A NEW TURBO?
Yes. Old clamps weaken over time, and a fresh OEM clamp ensures proper sealing and reduces the risk of leaks.
CAN THIS CLAMP FIX EXHAUST LEAKS AT THE TURBINE OUTLET?
If your leak is caused by a worn or stretched clamp, replacing it with the 3595658 will restore correct pressure. Always inspect sealing surfaces as well.
