Gear Reducer
The LENCO gear reduction unit, when used in conjunction with our Standard Design  or New Generation transmission, permits you to utilize a taller rear end gear but realize the advantage of a shorter launch ratio.  Since the taller ring and pinion provides more tooth area contact it is physically more reliable and less prone to breakage.  The LENCO gear reduction unit is available in a range of 31% through 56% and is perfect for the rigorous demands of Sand racers, Mud boggers, Modified and Mini-Rod pullers.

All LENCO floater axles come in your choice of Marage or 300M material.  31, 33, 35 and 40 spline configuration is available with your specified seating length.  Special order features such as rifle drilling and lightening are available.
