Product Description
Unlock reliable power and faster spool with the Industrial Injection Viper Phatshaft 63 (Part # 3632306801). Built around a proven 63mm compressor and 68mm turbine with a tight 12cm² housing, this drop-in, stock-location turbo is a killer upgrade for the 1994–2002 Dodge Ram 2500/3500 with the 5.9L Cummins—both 12-valve (1994–1998) and 24-valve (1998.5–2002).
Why Choose the Phatshaft 63?
- Stronger mid/top-end vs. stock HX35/HY35 while retaining street manners.
- 12cm² turbine housing for crisp response and towing-friendly drivability.
- Stock location fitment on OEM-style manifolds with common 2nd-gen hardware.
- Built to last: performance-balanced rotating assembly and robust journal bearings.
