I feel theres better axel control in the rear.

Mounted in the rear, the shock feels the axel dropping along with the rotational drop from the pinion rising in the front and the shocks rear mount lowering. So the shock is feeling downward movement only at the hit.

Mounted in front, the axel will be lowering but the shock mount will be twisting up. Momentarily canceling each others movment out. So there will be little shock control at that point.

I feel there best mounted in the rear, because of that.
