TRZ Motorsports 2" Drop Billet Spindles - Quick Steer Arm (1970 - 1981 Camaro / Firebird / 1975 - 1979 Nova) - 328-41 & 303-QS
2? Drop Billet Drag Spindles with Quick Steer Arms
The TRZ Motorsports 2? Drop Billet Spindles paired with Quick Steer Arms (303-QS) deliver a lightweight, precision-engineered front suspension solution for serious drag racers running 1970 - 1981 Camaro/Firebird or 1975 - 1979 Nova. Each spindle is CNC machined in-house from premium billet aluminum and features heat-treated stainless steel spindle pins for strength and long-term reliability under hard launches.
This setup includes castle nuts, keyed washers, and cotter pins, and is intended strictly for drag race applications. The Quick Steer Arms offer a major advantage - when used with rack-and-pinion steering, they can improve steering response and reduce turning radius by up to 30% compared to standard 303 steering arms.
Brake compatibility mirrors the stock-spindle geometry, supporting aftermarket bolt-on kits from Strange and TBM. These spindles do not work with Wilwood, Aerospace, or Baer brake systems. TRZ recommends using these with a bump steer kit, as the steering arms use a 1/2? tie-rod mounting hole that benefits from additional alignment tuning.
With approximately 15 lbs of weight savings over stock components, these spindles help improve weight transfer and front-end reaction for better drag strip performance.
