TRZ Motorsports 2" Drop Billet Spindles - 6.875? - with TRZ-303 Steering Arm - 1 Pair (A / F / X Body) - 328-2 & 303
Precision 2? Drop Billet Spindles with TRZ-303 Steering Arms
These TRZ Motorsports 2? Drop Billet Spindles paired with the TRZ-303 Billet Steering Arms deliver a purpose-built combination for serious drag racers running classic GM A, F, and X-body platforms. CNC machined in-house from billet aluminum and equipped with heat-treated stainless steel spindle pins, this setup drastically reduces front-end weight while improving geometry on lowered vehicles.
Designed to work with aftermarket brake kits that use the stock drum-spindle mounting pattern, these spindles are race-proven, lightweight, and engineered to handle the demands of hard launches and repeated cycles. The included TRZ-303 arms ensure proper steering compatibility and are required for installation, eliminating guesswork and ensuring a perfect fit.

Frequently Asked Questions
Why do these spindles require TRZ steering arms?
TRZ billet spindles use a dedicated mounting design that requires either the TRZ-303 Steering Arms or Quick Steer Arms (303-QS). Factory arms will not fit.
Will these work with my existing drag brakes?
If your brakes bolt to a stock drum spindle pattern - like Strange 328-Billet, TBM 328-Billet, or Wilwood 140-1017-BD - they will fit. Check your brake manufacturer's mounting pattern to confirm.
