Wicked Wheel® 2 for the 2005-2015 5.9L & 6.7L Cummins stock turbo
Greatly improves throttle response
Easy installation – no modifications needed
Holset turbos use two different style nuts holding the wheel on.
• If it is a 6 point nut, then tighten to 133 in/lbs.
• If it is a 12 point nut, then tighten to 124 in/lbs.
It is a left hand thread (reverse thread), meaning you turn the nut to the right to loosen.
