One of the first safety mods you should ever make to your Maverick should be adding a harness bar. A harness bar allows you to run the significantly safer 4 point harnesses. With all that power on the Maverick X ds Turbo you could get yourself into some dangerous situations and when those situations arise you will not want to count on the factory belts.
The harness bar is made from 1 3/4" Steel tubing with ultra strong 2" collars so it will hold up to almost anything. The bar is shaped as such it will fit ergonomically over the the Maverick's intercooler.
