Recently upgraded to Cobra rack and replaced this power steering shaft that had 2,334 miles on it. The Cobra rack was not a huge improvement over the FOX rack when coupled with MM aluminum rack bushings.
“You can sharpen your 1979-93 Mustang’s steering response with this Maximum Motorsports MMST-11 solid steering shaft assembly for power steering racks. With your stock Mustang steering shaft, motion is lost due to the flexing of the rubber rag-joint. This flexing usually feels like play in the steering wheel (you can move the steering wheel without the car changing direction). With a Maximum Motorsports steering shaft, the factory joints are replaced with race-quality needle-bearing U-joints, resulting in a dramatic improvement in steering response.”
I paid $239 for it...$180 shipped to lower 48.
