Garrett
GT37R Stage 3 Turbo Kit
1998.5 - 2002 5.9L Cummins Engine
The GT37R
dual ball-bearing turbo is a Garrett exclusive ball bearing
cartridge for unbeatable response, efficiency, and durability.
Elimination of the thrust bearing eliminates failures at elevated
boost levels. The upgrade results in lower intake and exhaust
gas temperatures as well as reduced backpressure for more
efficient air flow. The water-cooled center section with a
patented dual ball-bearing results in higher durability and
longer turbo life. Oil inlet fittings feature a built in restrictor
for worry-free operation.

Advantages of upgrade:
ball bearing cartridge for unbeatable response, efficiency
and durability
water-cooled center section for increased durability
Increased compressor flow capability compared to stage 1 and
2
modern GT-series high-flow compressor and turbine wheel
Increased turbine flow compared to stages 1 and 2
Increased compressor wheel size (88mm vs 82mm) compared to
stages 1 and 2
For a given performance level, this upgrade will provide:
1. Reductions in exhaust backpressure
2. Reductions in exhaust gas temperatures
3. Reduction in intake temperature
This stage offers the highest horsepower potential of the
three stages, at the expense of boost response (relative to
the others)
