This is a must for any vehicle! Our specially designed "X" members cut out the frame flex that time and more horsepower can cause in the original stock frames. Our top and bottom side tubes are formed as one piece, not miter-cut and re-welded square tube that can stress crack when the welds are ground.

Our "X" members are designed to accommodate the 4L80 transmissions as well as all manual & short shaft automatics for easy "drop out" from the bottom for servicing without raising the motor! Specify transmission being used. Includes bolt-in steel transmission mount . Vulcanized mount available seperatly.

If your vehicle isn't listed, we can custom build one for you. Fill out the our X-member Tech sheet and send it in for a price quote.

Doc Frohmader has written a tech article on his 1957 GMC long bed truck. Our tubular X-member was a key element in re-enforcing the frame.
