TRZ Motorsports Stock Height Billet Spindles - No Steering Arm - 1 Pair (1970 - 1978 Camaro / Firebird / 1975 - 1978 Nova) - 328-31
Lightweight Stock-Height Billet Spindles for 1970 - 1978 F-Body & 1975 - 1978 Nova
These TRZ Motorsports Stock Height Billet Spindles are engineered specifically for drag race applications on 1970 - 78 and 1979 - 81 F-body platforms (Camaro/Firebird) as well as the 1975 - 79 Nova. Built entirely in-house, each spindle is CNC-machined from billet aluminum and equipped with heat-treated stainless steel spindle pins, delivering exceptional strength with massive weight reduction.
This spindle set does not include steering arms, but must be paired with compatible TRZ 6061 billet steering arms (Part #303) or the optional 303-QS Quick Steer Arms, which improve turning radius by up to 30% when used with rack-and-pinion conversions. These spindles are designed strictly for drag racing and are compatible with aftermarket bolt-on brake systems intended for factory spindles - specifically Strange and TBM categories within the TRZ 328-Billet line.
These spindles offer a significant 15 lb weight savings compared to stock, making them a high-impact upgrade for racers looking to improve front-end response, reduce unsprung mass, and gain consistency off the line.
