TRZ Motorsports Stock Height Billet Spindles - with 303-QS Quick Steer Arms - 1 Pair (1970 - 1978 Camaro / Firebird / 1975 - 1978 Nova) - 328-31 & 303-QS
Stock-Height Billet Spindles with Quick Steer Arms for 1970 - 78 F-Body & 1975 - 78 Nova
The TRZ Motorsports 328-31 & 303-QS package delivers stock-height billet spindles paired with TRZ's Quick Steer (303-QS) Arms, engineered for racers who want sharper steering response and reduced turning radius in their 1970 - 78 / 1979 - 81 Camaro & Firebird and 1975 - 79 Nova. CNC'd in-house from billet aluminum and paired with heat-treated stainless steel spindle pins, these are lightweight, ultra-strong, and purpose-built for drag race applications.
The 303-QS Quick Steer Arms included in this kit can improve turning radius by up to 30% when used with rack-and-pinion steering - ideal for maneuvering in the pits or staging lanes. These arms also feature a 1/2? straight tie-rod hole, making them bump-steer - friendly and ready for precise frontend geometry tuning.
This assembly supports aftermarket brake systems designed to fit OEM-style spindles - specifically Strange 328-Billet and TBM 328-Billet kits. TBM brake users must select the correct 2-piston or 4-piston caliper bracket when ordering. Aerospace, Baer, and Wilwood systems are not compatible.
