18. As the name implies, this kit utilizes four bars to locate the rearend. In the g-Bar kit, these have poly end bushings, but we opted for the g-Link kit with its deflection-free pivot-ball assemblies. Zero deflection translates into more precise handling, and given how we drive, we thought this was the way to go. For those who want to make more of a fashion statement, the lower links can be upgraded to billet. Before installing, we set the lower bars to 24 inches and the upper bars to 9.5 inches eye-to-eye.
