The stock antisquat bracket is shown on the right. It is the connection from frame to upper control arm and has no provision for tuning. Brayman replaced it with Global bits, which are adjustable and preclude the need for shims behind them (used to set pinion angle in the stock setup). Excessive squat during acceleration will cause the rear tires to spin. Adjusting the lower control arm down at the rearend will change the percent of antisquat, thus increasing the amount of traction. The antisquat kit will allow you to readjust the angle of the lower arm thereby increasing traction.
