The long arm will stop the rearend from twisting but will not affect the springs in a situation like going up a driveway or around a tight corner. This technology can be found on the IROC generation of Camaros, and it worked well for Chevrolet, so it should work for our X-Runner. Not only can we now put the tires up into smoke but also the truck transfers weight much better, allowing us to launch harder withoutspinning the tires. So this part gives you the best of both worlds, the ability to impress your buddies with lots of tire smoke and still gate the sucker next to you and leave him at the line.
