Our supply chain is suffering major pandemic-related disruptions. Many of our suppliers shut down for a time, and like us are operating with reduced manpower. Meanwhile, demand for MM products has skyrocketed. Thank you! We’re a small company and we regret our website isn’t fancy enough to inform you of back orders when you buy something. Please understand that we’re working as fast as we can to fill your orders.

UPS Shipping Times As of March 24, UPS no longer guarantees the shipping time for any shipment. i.e., expect shipping time to lengthen.

1984-86 SVO Mustang Spindle Tech

This spindle was fitted to the limited production SVO Mustang. It has many similarities, as well as many differences, with the 1987-93 V8 Mustang spindles.


  • Tapered roller bearings
  • 1-piece hub and rotor assembly
  • Nominal rotor diameter of 11".
  • Spindle, rotor and caliper were sourced from a Lincoln.
  • Diameter of the ball joint taper is that of the Lincoln, which is larger than a typical Mustang ball joint. This requires a ball joint adapter when swapping this spindle onto any other 1979-04 Mustang ball joint.
  • Steering arm geometry is slightly different than that of the other Mustang spindles of the same era, increasing the Ackerman geometry effect, but also slowing the steering ratio.
  • Strut mounting ear is 0.230" (5.9mm) thinner than the first generation Mustang spindle.
  • Bolt holes for the strut mounting are 0.130" (3.3mm) further apart than the first generation Mustang spindle; are the same as the 1987-93 V8 Mustang spindle, and all 1994-04 Mustang spindles.
  • Caliper is very similar to that of the 1987-93 Mustang, except the diameter of the brake caliper piston is larger (73mm). This caliper was chosen to match with the rear disc brakes fitted to the SVO Mustang.
  • Original SVO front calipers were fitted with phenolic plastic pistons; some rebuilt calipers have steel pistons, which have greater heat resistance and are therefore more desirable for track use.
  • Different piston materials have different requirements for inner brake pad retaining clips.
  • Unique ears for mounting the stock caliper; aftermarket calipers cannot be installed without significant modifications to the spindle.
