KC38r Stage 3 Dual Ball Bearing Turbo - 7.3 Power Stroke (E99) - .84 A/R (Special Cover)

That’s right, the Original KC38r is back and better than ever! We have spent several years on research and development modifying and battle testing our original ball bearings so that we could bring you the best and most reliable ball bearing design KC Turbos has ever produced.

The new KC38r compressor wheel is drastically different, it is a larger 7x7 KC300x Gen 2 compressor wheel. This newly redesigned compressor wheel is based on the 366SX-E compressor wheel and shares a similar blade profile except it is reverse rotation.

The Turbine Wheel also takes design notes from the 366SX-E but its larger diameter offers more flow and increased strength through the introduction of thicker blades, a thicker hub, and a thicker rear webbing making it much less prone to fatigue and wheel burst. The redesigned dual ball bearing center housing has been modified to accept the turbine’s increased shaft thickness from a 6.4mm on the original to 7.5mm for increased strength and longevity.

This dual ball bearing turbo will surprise you at how much it will wake up your 7.3! We have torture tested it for longevity, proven its capability on the dyno, and at the Race Track. For dedicated tow rigs and daily drivers, the .84 A/R Housing provides a quicker spool and cooler EGT's below 3000 RPMs.
