QA1 9056-120 2in Drop Spindles, 99-06 Silverado/Sierra 1500 2WD Product Overview Looking for a clean way to lower the front of your NBS truck without compromising ride quality? QA1’s 2" drop spindles are a simple, effective solution for achieving a lower stance while preserving suspension geometry and steering performance. Designed specifically for 2WD 1999–2006 Silverado 1500 trucks, these spindles work seamlessly with QA1 coil-overs and control arms. CLEAN, CONSISTENT FRONT DROP These spindles deliver a true 2" front drop by lowering your truck at the spindle instead of changing spring height. That means your suspension travel and steering geometry stay intact—giving you the stance you want without the harsh ride or alignment headaches. COMPATIBLE WITH FACTORY OR QA1 CONTROL ARMS These spindles are engineered to work with OEM control arms or QA1’s tubular upper and lower arms—giving you flexibility whether you're keeping your stock setup or upgrading to a full QA1 suspension system. FITMENT NOTES Fits 1999–2006 Chevrolet Silverado / GMC Sierra 1500 2WD with coil spring front suspension: Requires 17” wheels or larger: Not compatible with vehicles originally equipped with torsion bar front suspension

Lower the front of your 2WD truck with QA1 QAP9056-120 2-inch drop spindles, engineered for 1999-2006 Chevrolet Silverado and GMC Sierra 1500 models equipped with coil spring front suspension. These spindles provide a clean, consistent lowered stance while helping preserve factory suspension geometry, steering performance, and available suspension travel. By lowering the vehicle at the spindle rather than changing spring height, they help maintain a more controlled ride compared with lowering methods that reduce spring travel.
QA1 QAP9056-120 drop spindles are designed for compatibility with original equipment control arms as well as QA1 tubular upper and lower control arms. This makes them a practical choice for a stock suspension refresh or as part of a complete QA1 suspension upgrade. The bolt-on design supports straightforward installation using standard suspension components, while the durable finish helps resist corrosion during long-term street use.
These 2-inch drop spindles fit 2WD 1999-2006 Chevrolet Silverado 1500 and GMC Sierra 1500 trucks with coil spring front suspension. They require 17-inch wheels or larger for proper clearance and are not compatible with vehicles originally equipped with torsion bar front suspension. Verify vehicle configuration and wheel clearance before installation. The pair is supplied as a matched solution for lowering the front of your truck while retaining a balanced, functional suspension setup.
