QA1 Double Adjustable Pro-Coil kits are an excellent choice for any GM muscle car owner looking for a better stance, ride quality and performance. These easy-to-install bolt-in kits are a great solution for adjustable ride height, and the double adjustable valving provides ample range of tunability from the street to the track. DIAL IN THE PERFECT STANCE Achieving the perfect, level stance is critical for the overall look and appearance of your car. GM Pro-Coil kits offer 0 to –2 inches of ride height adjustability, allowing you to dial in the perfect stance for your Chevelle, GTO, Monte Carlo, El Camino, among many others. Adjustments within this range can be made with a simple turn of the spring seat nut. For an additional drop beyond 2 inches, consider adding drop spindles to your car. TUNE YOUR PERFORMANCE & RIDE COMFORT Double-adjustable coilovers are ideal for drivers looking for great performance on the street or track. Independent tuning of compression and rebound allows you to fine-tune the handling or straight-line performance of your vehicle for any driving condition. Accessing the 18-position knob is easy, and by turning the steering wheel to full lock, you can reach in and make your tuning adjustments at the base of the shock. QA1 Pro-Coil kits feature high-travel coil springs built to deliver optimal performance. Spring rates are tailored to your vehicle's weight and driving style. Need help choosing the correct spring rate? Watch this video ! EASY, BOLT-IN INSTALLATION GM Pro-Coil Kits seamlessly bolt-in with both Original Equipment (OE) stamped steel control arms or QA1 tubular control arms. This gives you the flexibility to use the kit with your existing setup or upgrade your control arms for additional performance gains. FEATURES AND BENEFITS • Up to 2” of ride height adjustment allows you to dial in the perfect stance. • Achieve the ultimate balance of ride quality and performance handling with independent tuning of rebound and compression valving. • Easy bolt-in installation that works with your factory or upgraded QA1 tubular control arms.

Manufacturer's Warranty — QA1

Manufacturer's Warranty — QA1
This shock belongs to one of QA1's select limited lifetime warranty lines — Stocker Star, Proma Star, Ultra Ride and Aluma Matic. QA1 warrants it to the original purchaser to be free from defects in material and workmanship for as long as you own it; the warranty is non-transferable. Registration is required: shocks purchased on or after 9/1/2020 are eligible, and for purchases from 1/1/2021 onward you must register at QA1.net/Warranty within 30 days of purchase — not following QA1's warranty procedure voids the coverage. All other QA1 products carry the standard one-year warranty. Coverage does not apply to cosmetic wear from normal use, improper or abnormal use, abuse, neglect, vehicle accident, insufficient travel, incorrect installation or maintenance, or to a product that has been repaired, altered, or run with parts other than genuine QA1 parts. QA1's remedy is repair or replacement at its option (no refunds); labor, removal and other repair charges are not covered. A claim needs an RMA number issued by QA1, and the customer pays shipping to QA1 for inspection.
Warranty terms are set by the manufacturer and may change. Full details and claims are handled directly by QA1. Contact us if you need help with a warranty claim.
