Steering Shaft Assembly, Manual Steering Rack, 1979-93 Mustang
Solid Steering Shaft Assembly fits manual steering rack equipped 1979-93 Mustang
- This new MMST-12.1 Steering Shaft fits the just-redesigned Flaming River manual steering racks.
- It also fits the previous generation of Flaming River manual steering racks, as well as OEM Ford manual racks and other aftermarket manual rack brands.
- The first generation MM Steering shaft (MMST-12) does NOT fit the newest Flaming River manual steering racks because Flaming River changed the retention feature on the input shaft on all of their manual steering racks.
- The earlier Flaming River racks have a circular groove machined entirely around the input shaft. The newest Flaming River racks have a circular groove only on one side of the input shaft that intersects the shaft in a straight line. The new retention feature prevents use of the MMST-12 Steering Shaft.
- Required when converting to manual steering rack.
- Improves steering response by eliminating deflection allowed by the stock rubber rag joint.
- Reduces annoying play at the steering wheel.
- Stays secure because there are no setscrews to loosen.
- Improved header clearance at the lower U-joint.
- Precise fitment to your Mustang because its telescoping length accommodates different steering rack positions.
- Easier installation because it can be collapsed to a shorter length than stock, then extended to fit.
- Improved safety because it adds a collapsible section between the rack and the firewall.
- U-joints are welded to the shaft, no setscrews to loosen.
- Lower connection only fits manual rack input shaft.
- Attaches to steering rack with a pinch-bolt clamp (just like OEM) instead of a setscrew.
- Two race-quality needle-bearing U-joints replace the rubber rag joint and the upper pin-and-block U-joint.
- Telescoping design allows lengthening, up to 1.1" longer than stock shaft, to allow repositioning of the steering rack.
- Unique design of the collapsible center section prevents the two halves from pulling apart.
- Collapses shorter than a stock shaft.
