TBC-50 is a rear lower control arm that accepts the stock or performance spring. The arm removes bind in the rear suspension. It allows the lower arm to pivot properly without twisting the mounting brackets on the frame. This is accomplished by installing a spherical bearing in the lower arm. The bearing is Teflon lined so no lubrication is necessary. The control arm is quiet because a rubber bushing is installed at the rear end side keeping the rear end and road noise out of the loop. Rear end stability is greatly improved and cars with serious horsepower can easily benefit from using these arms because of their control.
Lower rider applications and hydraulic cars will also enjoy the amount of travel that is available.
