TRZ Motorsports Stock Height Billet Spindles with 303-QS Quick Steering Arm - 1 Pair (A / F / X Body) - 328-1 & 303-QS
Lightweight Billet Spindles with Quick Steer Arms for GM A, F & X-Body Drag Cars
The TRZ Motorsports Stock Height Billet Spindle Package with 303-QS Quick Steering Arms delivers faster steering response, improved maneuverability, and major weight savings for GM A-body, F-body, X-body, and early Corvette drag applications. Machined 100% in-house, these billet spindles feature heat-treated stainless steel spindle pins for maximum strength and reliability under hard launches.
The included 303-QS Quick Steer Arms are engineered to increase turning radius capability by up to 30% compared to the standard 303 steering arms - an excellent upgrade for cars running rack & pinion steering or limited front-end space. TRZ also recommends using a bump steer kit, as the arms use a 1/2? straight tie-rod hole for adjustability and precision.
Designed strictly for drag applications, these spindles are compatible with aftermarket bolt-on disc brake kits intended for stock drum spindles, including Strange, TBM, and Wilwood (140-1017-BD). At roughly half the weight of OEM cast spindles, they offer meaningful front-end weight reduction to help your car leave harder and more consistently.
