IMHO it's not too hard to improve on this kit. The tools are low quality and heavy. The big box end wrench is for the front and rear axle nuts. I replaced mine with Motion Pro aluminum tools that have tire spoons on one end and axle box wrench on the other. They're lighter, longer (more leverage), and serve multiple purposes.
