Tru-Square Mini Sprint Rearend Alignment Tool, 2 Spacers, 2 Inch Axle
                        There are three (3) different Tru-Square tools for Mini/Micro Sprints depending on your axle. Here are directions to find out which tool you need:

Set your rear axle on your setup blocks of choice. Be sure your spacers are on and your rear axle nuts are tight so the birdcages are not loose.

The Tru-Square tool clamps to the axle directly above the setup blocks, therefore the tool that is needed is determined by the overall diameter of the axle or axle spacer (if applicable) at this location. Measure the diameter of your rear axle or the diameter of the spacer (if there is a spacer on the axle) directly above the set up blocks. Your measurements should be: 

  • 2" (on both sides) 
  • 2.5" (on both sides) 
  • 2" on one side and 2.5" on the other

This fits long spline axles which have axle/wheel spacers covering the axle at the point of tool contact on both sides of the axle.

  • Quick attachment system for rear end squaring
  • All aluminum construction
  • Hardware is included
