Description:
The Tractor Tracker "U" Bolt Extension Set is used to measure the tandem axles on tractors in relationship to the front spring "U" bolts. See diagram below.
The extenders establish a measuring point to the "U" Bolts on front axles to measure to the rear tandems.
As shown on the diagram measurements, "A" and "D" should be the same, and "B" and "C" should be the same if the vehicle is tracking correctly on the front axle. Two of the extenders have 7/8" threads and two have 3/4" threads to accommodate the most popularly used "U" Bolts.
The extenders are designed to be used with either of the Tandem Tracker Series for steel or aluminum wheels, and in combination with the Tandem Caliper and Trailer Kingpin Extension.
