Features
- CNC machined billet aluminum spindles with heat treated stainless steel pins
- 3 piece design with no welds or seams
- About 4 lb per spindle, 8 lb per pair, much lighter than stock Fox and SN95 spindles
- Strut mount flange is .750" wide and fits the factory Fox Body GT mount
- Titanium pins (TRZ 32601-TI) are offered as an upgrade and save just under 1 lb. Contact us for a price
What's included
- Bolt-on billet steering arms for a 1/2" rod end
- Castle nuts, keyed washers and cotter pins
- Steering arm bolts
- ARP stainless caliper bolts
- Ball joint spacers for Fox Body ball joints
Brake compatibility
- Spindle mount brakes from Strange and TBM
- Hub style brakes from Strange and TBM with the 5 x 4.5" Ford bolt pattern
- Certain Baer SS4 Deep Stage kits in 5 x 4.5" (Ford) and 5 x 4.75" (GM). Contact us for details
- Mustang brakes made for the factory spindles will not work
Fitment notes
- The 4" drop requires a 17" front wheel
- Long travel struts may interfere with the spindles and steering arms
- Strut to spindle bolts must be 5/8" diameter. Stock hardware will not work
- Fox Body (1979-1993) ball joints need the included spacer below the castle nut
- 1994-2004 Mustangs may need an A-arm narrowed 1" or more, depending on the caster camber plates on the car
- Adjustable A-arms are recommended
- For spindle mount wheels, the design is based on the large bearing of the Strange GT strut. It does not fit the Anglia or Strange Ultra struts
Steering arm length
- The steering arms have two outer tie rod holes
- The hole closer to the spindle gives factory length
- The outer hole is 1-1/2" longer, which helps when the steering rack sits 2" or more ahead of the stock location
