G.D.S. | CH-02 Dodge Cummins 5.9L Holset Turbo H1 Upgrade Housing & Wheel
Couldn't load pickup availability
This Genuine Holset Upgrade Housing & Wheel combo for 1988-1991.5 Dodge / Cummins 5.9L Turbochargers is the largest available, increasing compressor flow capacity and reducing compressor surge on non intercooled trucks. Featuring 60mm inducer size, it is a must-have upgrade for a massive performance boost.
Both intake hose connections on this compressor housing are larger than stock, and require changing to a 4" intake hose and 2.5" compressor discharge hose! These modifications are the customers responsibility to provide. See below for the conversion kit to help with this modification.
IMPORTANT Please take note: In order for it to drop in place you will need to order our H1C conversion kits for the compressor intake and discharger to mount correctly to the factory piping.
