On the rear Axles, their is enough vibration that the torque on the halfshafts bolts will come loose after one session on the track....many times when we come off the track we had to check & re-torque these bolts after every session.

Jet Nuts reduced the amount of times that the torque was reduced and we could go many sessions....we still checked the torque but it was good.
