FRONT COIL-OVER SUSPENSION SYSTEM,S-ADJ,63-87 C10,SGL ADJ 750 LB SPRINGS

Brand New QA1 Front Coilover System, Single Adjustable, Compatible with 1963-1987 GM Trucks (Part #52611-S750).

Upgrade the front suspension of your 1963-1987 Chevy C10 with the QA1 Front Coilover System. Designed to work with the factory chassis, this complete system combines tubular upper and lower control arms, single-adjustable coilovers, and 750 lb/in springs to deliver improved handling, easy suspension tuning, and an adjustable lowered stance.

GET THE STANCE YOU WANT: Lower your C10 without being locked into a fixed ride height. Fully threaded coilover shock bodies provide up to 3" of adjustable front drop, making it easy to fine-tune your truck's stance. Pair the system with compatible 2" drop spindles to achieve up to 5" of total front drop for an even more aggressive look.

IMPROVE HANDLING AND STABILITY: QA1 tubular upper and lower control arms feature performance-focused suspension geometry with increased caster capability. The additional caster helps improve straight-line stability, steering feel, and responsiveness, giving your classic C10 a more confident, modern feel behind the wheel.

DIAL IN YOUR RIDE: QA1 single-adjustable coilovers make it easy to tune your truck's ride and handling. A simple turn of the adjustment dial changes compression and rebound together, allowing you to choose a softer setting for comfortable cruising or a firmer setting for more responsive handling.

MATCH YOUR TRUCK'S SETUP: This system features 750 lb/in coilover springs, providing an option for matching the front suspension to your truck's weight, configuration, and intended use. Combined with QA1's adjustable shocks, the system gives you the flexibility to fine-tune suspension performance around how you use your C10.

BOLT-ON PERFORMANCE: Get the benefits of a modern coilover suspension while retaining your factory chassis. The system includes tubular upper and lower control arms, single-adjustable coilover shocks, springs, upper mounting brackets, and installation hardware for a straightforward front suspension upgrade.
