TA manufactures the ultimate bolt on traction bar for the `64-`72 GM A-body cars. Commonly referred to as ”No Hop” bars, they improve traction and reduce 60 foot times. TA has done this by relocating the upper control arm to produce the correct instant center location. In changing the instant center location, the chassis will try to drive the rear end downward and lift the front end up, thus concentrating the weight of the vehicle on the rear tires. Stock suspension is designed to do the opposite. It tries to draw the rear end and the body together which reduces the downward force, therefore reducing traction.TA’s traction bars are cut and machined from billet steel and powder coated for corrosion resistance and appearance. The billet material we use is stronger than the cast bars that our competitors offer, plus they have better fit and finish.
