The TCI High Performance Flex Bands feature band linings with a higher coefficient of friction for higher torque capacity and the ability to produce quicker, more positive band engagement. TCI also carries a line of bands, referred to as Powerbands that include the bullet-proof material, Kevlar. The powerbands are up to 18% wider than OE bands, providing greater torque capacity and more positive shifts and band apply. The anchor area on these bands is extra thick, heat-treated, high-carbon steel construction to eliminate the stretching and breakage often associated with stock bands. These bands are a must for any street, towing or competitive application.
