Holset HY35 HE341 HE351CW turbo rebuild kit fits: 1999 - 2002 Dodge Ram Cummins with Automatic transmission HY35 turbo (54mm x 78mm compressor wheel + 58mm x 65mm turbine + turbine housing mounts to bearing housing with vband clamp, has 5” bearing housing but .040” shorter than he351cw) 2003 - 2004 Dodge Ram Cummins HE341 turbo (54mm or 56mm x 78mm compressor wheel + 58mm x 65mm turbine + no boost control solenoid on compressor housing + bearing housing is .040” shorter than he351cw making compressor wheel go in .040” more than he351cw bearing housing.) 2004.5 - 2007 Dodge Ram Cummins HE351CW turbo (59.96 x 86 compressor + 58mm x 65mm turbine + boost control solenoid in compressor housing) This kit includes: Machined from Copper Bar Upgraded Thrust Bearing with larger oil feed holes which is critical for longevity 2 Journal Bearings with oil grooves in center for increased oiling and durability 4 retaining clip journal bearings 1 Thrust Collar 1 Thrust Spacer 2 staggered front and rear piston ring seals for better sealing from oil leaks Front Seal Plate Oil Deflector Oil Feed Gasket Oil Return Gasket 1 Rubber O-ring for Front Seal Plate 1 Rubber O-ring for Compressor Housing (you may need to machine your bearing housing for this install unless yours is already done) 1 Rear Heat Shield NOTE: This is NOT for VGT Turbos such as HE341VE HE351VE and HY40V The problem with most aftermarket holset rebuild kits is: the feed holes in the thrust bearings are not drilled big enough causing lack of oiling to the thrust bearing which causes failure over time. The thrust bearing from other sellers is often made from softer materials which will cause thrust bearing failures at high boost levels. 3 major advantages to our rebuild kit is: (1) our machined from copper bar thrust bearing has large high flowing oil feed holes for increased oiling lubrication and cooling which increases durability which is critical for high boost applications. (2) Our rebuild kit has staggered front and rear piston rings Which provide better sealing than the factory piston ring seals because it eliminates the gap of the piston rings creating a 360 degree seal. (3) Our journal bearings has grooves in them increasing the oiling all the way around the journal bearing for added cooling and lubricant which provides additional durability which is importantl for applications with increased boost levels. The difference in our kit and other sellers is that we use our rebuild kits in our own performance turbo builds!
