The GKTech weld in K-Frame/Tension rod plates have been designed to help brace one of, if not the most necessary area on your S-chassis. Tension rods put an immense amount of load on the K frame and the K frame itself flexes under load a visually noticeable amount. Our weld in plates will help eliminate this which will result in better overall handling and steering feedback. The added benefit is that if you ride over a ripple strip at the race track (or a gutter on the street) the flat bottom of the K frame will help glide you over rather than you getting stuck and pulling half your car to pieces.
