TCI's Powerbands
TCI's Powerbands are made from a Kevlar bullet-proof material and are up to 18% wider than original equipment. Powerbands provide greater torque capacity and more positive 1-2 shifts. The band's anchor area is constructed of extra thick, heat treated, high-carbon steel to resist the stretching and breakage associated with stock bands.
