TRZ Motorsports Billet Aluminum Drop Spindles - Spindle Mount - 4" Drop - Factory Length Steering Arm (1979 - 2004 Ford Mustang) - 326-MUS-41
Maximum-Low 4? Drop Billet Spindles with Factory-Length Steering Arms for Drag Mustangs
For racers who want their Mustang sitting as low as physics allows, the TRZ Motorsports 4? Drop Billet Aluminum Spindles deliver extreme stance with the suspension geometry to match. Designed for dedicated drag race builds across all 1979 - 2004 Foxbody, SN95, and New Edge Mustangs, these ultra-low spindles are CNC'd in-house with heat-treated stainless steel spindle pins - and can be upgraded to titanium pins for additional weight savings.
At this level of drop, wheel clearance becomes critical, which is why TRZ specifies the use of a 17? front wheel minimum. The factory-length steering arms maintain OEM-style steering geometry and work with 1/2? rod-end setups. TRZ's exclusive 3-piece billet spindle design eliminates welds and seams, ensuring maximum strength with minimum weight - just 4 lbs per spindle.
These spindles are fully compatible with spindle-mount and hub-style drag brake systems from Strange and TBM, along with select Baer SS4 Deep Stage kits. They correct strut height, drastically reduce unsprung mass, and provide the ultra-low ride height many serious drag race builders want.

Frequently Asked Questions
Do I really need 17? wheels for the 4? drop spindles?
Yes. TRZ specifies that the 4? drop requires at least a 17? front wheel for brake and spindle clearance.
Can I run factory Mustang brakes on these spindles?
No. These spindles do not fit OEM Mustang brakes. They require aftermarket drag-race brake kits.
