Track only driveshaft travel

The amount of slip yoke travel (standard 3/4" - 1") is based on your rear suspension (vertical travel). If your rear end is shoved up into the body so that it has limited travel then you don't need as much yoke travel. Normally the rear end can travel "vertically" about 12 inches in the streets. When the rear end travels towards the body the yoke goes further into the transmission. If your body is lowered you have limited the amount of "yoke" movement.
