uses a secondary design with the helix built into the clutch. Because of this, we can only change the secondary spring. This works great until you get to tires over 32" tall. At that point, we strongly suggest upgrading the secondary to the Team Tied option where I can match the helix angle to the load for improved backshifting and response.
