H1c upgraded rebuild kit 

H1E H1C WH1C upgraded turbo rebuild kit fits:

• 1989 - 1994 Dodge Ram 5.9 Cummins H1C WH1C intercooled and non intercooled turbo chargers
• Holset H1E turbo chargers commonly found on 8.3 Cummins engines

Fixes the common thrust wear issue on the H1E, H1C, and WH1C turbo.  The factory thrust bearing only has 1 oil port and 50 % less surface area. The upgrade has 2 oil port and a full 360 degree thrust bearing surface to copy the quality of the HX35.

H1C rebuild kit includes:

• upgraded dual 360 degree thrust bearing
• compressor housing o-ring
• compressor plate o-ring
• 4 compressor plate bolts
• 4 turbine bolts
• 2 turbine housing clamps
• 3 thrust bearing bolts
• 1 compressor nut
• H1C H1E WH1C front collar
• H1C H1E WH1C bottom collar
• 4 bearing retainer clips
• 2 H1C journal bearings 
• front piston ring stepped gap upgrade
• rear piston ring stepped gap upgrade 
• 1 oil drain gasket
• 1 oil feed gasket
• 1 heat shield
• 1 t3 twin scroll manifold gasket

The problem with the factory H1E H1C WH1C holset rebuild kits is: the factory thrust bearing only had 1 oil feed hole and a weaker webbed design thrust bearing, which was very weak and caused immediate  failed when more than factory boost was applied.

2 major advantages to our rebuild kit is:

(1) our machined from copper bar H1C H1E WH1C thrust bearings are fully 360 degree and have 2 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.

The difference in our kit and other sellers is that we use our rebuild kits in our own performance turbo builds!
