In order to get the desired drive characteristics we were looking for, we created custom go cart knuckles.

Instructions
- Mark and cut your DOM tube to 2.125″ long
- Using a dremel or .625″ flapwheel, clean the inside of the DOM tubing .75″ deep on each end.
- Using a vice or mallet, press the bushing into either end of the tube.
- Take your 3/4 “Axle” bolt and cut at 10degree angle. (This can be done using a wooden jig or on a chop saw that allows for angled cuts.)
- Cut out TRE mount out of sheet steel or do nothing if pre-purchased.
- Weld “Axle” bolt to the center of your DOM tubing.
- Weld the TRE mount to the top or bottom of the bolt 90degrees offset
- Place welded assembly inside of Spindle Bracket
- Insert 1/2-20 bolt and tighten the nut down, enough that it seats but does not crush the Spindle Bracket.
