TRZ Motorsports 2" Drop Billet Spindles - TRZ-303 Steering Arm (1970 - 1981 Camaro / Firebird / 1975 - 1979 Nova) - 328-41
Billet 2? Drop Spindles with TRZ-303 Steering Arm for F-Body & Nova
The TRZ Motorsports 2? Drop Billet Spindles with TRZ-303 steering arm compatibility are engineered for racers who want lighter weight, improved geometry, and precision-built components on their drag race - focused F-body or Nova. CNC'd in-house from high-strength billet aluminum and paired with heat-treated stainless steel spindle pins, these spindles deliver the durability and consistency needed for serious competition.
This spindle kit fits 1970 - 1978 and 1979 - 1981 Camaro/Firebird along with 1975 - 1979 Chevy Nova. TRZ includes castle nuts, keyed washers, and cotter pins, making this a complete bolt-on solution for cars running aftermarket brakes designed for factory spindle geometry. These work with Strange and TBM front brake setups, but do not fit Wilwood, Aerospace, or Baer systems.
These spindles must be used with TRZ's 6061 billet steering arms (Part #303) or Quick Steer Arms (303-QS). Quick Steer Arms can improve steering response and reduce turning radius by up to 30% when used with rack-and-pinion conversions. Because the steering arms feature a 1/2? tie-rod hole, TRZ recommends pairing them with a bump steer kit to maintain proper geometry through suspension travel.
Each set yields up to 15 lbs of weight savings over stock spindles, helping your F-body or Nova transfer weight quicker and react harder at launch.
