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.
