TRZ Motorsports Billet Aluminum Spindles for Stock-Type V8 Brakes (1979-1993 Mustang)

Billet aluminum spindles from TRZ Motorsports for the 1979-1993 Mustang, made for race brakes that fit the Mustang V8 spindle. Sold as one pair of spindles with one pair of billet steering arms and hardware. Choose stock height or a 2" drop.

Features

• CNC machined in house by TRZ from billet aluminum, with heat treated stainless steel spindle pins
• 3 piece design with no welds or seams
• About 4 lb per spindle, 8 lb per pair, much lighter than stock Fox spindles
• Strut mount flange is 3/4" (.750") wide, the same as the factory Fox Body GT mount
• Works with all commonly available ball joints

Which height

• 2" drop: corrects front suspension geometry and installed strut height on lowered cars
• Stock height: for stock height to slightly lowered cars, and leaves more strut compression for maximum strut extension

What's included

• 1 pair of billet aluminum spindles
• 1 pair of bolt-on billet aluminum steering arms for a 1/2" rod end
• Castle nuts, keyed washers, cotter pins, ball joint spacers and steering arm bolts

Brake compatibility

• Aftermarket 1987-1993 Mustang stock-type disc brake kits (V8 spindle) from Strange and TBM
• Wilwood kits for the V8 spindle, 140-14420D and 140-4503. The caliper bracket must be trimmed to use the 2 side caliper bracket bolts, and you need to supply 3/8-16 x 1" flat head bolts
• Aerospace kits for the V8 spindle. The caliper bracket must be trimmed to use the 2 side caliper bracket bolts
• Will not work with actual stock brakes

Fitment notes

• Long travel struts may interfere with the spindles or steering arms
• Fox Body (1979-1993) ball joints need the included spacer below the castle nut. SN95 and New Edge (1994-2004) ball joints do not
• Strut to spindle bolts must be 5/8" diameter. Stock hardware will not work
• A 1994-2004 Mustang needs an A-arm narrowed 1" or more, depending on the caster camber plates on the car, to use these 79-93 Fox spindles
• Adjustable A-arms are highly recommended

Steering arm length

• The steering arms have two outer tie rod holes
• The hole closer to the spindle gives factory length, with a 1/2" tie rod hole
• The outer hole is 1-1/2" longer, which helps when the steering rack sits 2" or more ahead of the stock location
