Cummins X15 Performance Series HE400VG Turbo | 5459711 - IN STOCK!

If you need a new turbo for a Cummins X15, you may have been struck with sticker shock by the dealer, we have your solution!  Brand new aftermarket turbocharger for fitment on Cummins X15 Engines.  Cross over part numbers below.  This turbo is new, not reman!   Does NOT include actuator, please contact us if you need one.

Direct replacement for PERFORMANCE SERIES X15, or can be used as an UPGRADE for the EFFICIENCY SERIES X15.

The main difference between the X15 Efficiency Series turbo and the X15 Performance Series turbo is the compressor wheel.  The efficiency series uses a 62MM wheel that has more of a round contour design. The performance series compressor wheel has a more of a straight cut 66MM wheel.  For customers using this turbo as an upgrade, you can expect CFM gains from the larger wheel.  This does not necessarily mean more boost pressure, but more boost VOLUME, which is what you want!

Fits and functions identically to the original turbo.  No modification necessary!  Install with your actuator, calibrate, and go!
