This is a replacement pinion for the Titan Steering Racks that we carry (custom and stock). Ratio of this unit comes out to be 2.54" of rack travel for every rotation of the pinion. This is the same ratio we normally supply.
If you would like to slow down the steering, we also offer a 7 Tooth 12DP Steering Pinion (Part No. 1807), which moves the rack 1.97" per turn.
