Covers built for the GMC Syclone
The 1991 GMC Syclone is a turbocharged all-wheel-drive performance pickup — a rare one-year truck with a low, purposeful body that's nothing like a work truck, so a fitted cover matters. EliteShield's Syclone cover is patterned to the Regular Cab with the short bed so the fabric follows its lines, clears the mirrors and stays snug. Choose from four protection tiers: ShieldAll Ultimate™ and Elite Supreme™ (fleece-lined, UV-treated, water-resistant and breathable, up to a 3-year warranty), the lightweight Elite Premium™ (2-year), or the value Elite Economic Guard™ (1-year). Every cover has elastic hems and grommets for a snug fit, is built for indoor or outdoor use, and guards your Syclone against UV fade, rain, dust and scratches. Choose 1991 above.

GMC Syclone cover questions
Quick answers to the most common questions.
Is there a cover for the GMC Syclone?
Yes — the 1991 Syclone, GMC's turbocharged performance pickup, is patterned to the Regular Cab short-bed so the cover follows its low sport-truck body. A With-Shell size is available.
What warranty comes with a GMC truck cover?
It depends on the fabric tier: ShieldAll Ultimate™ and Elite Supreme™ carry up to a 3-year warranty, Elite Premium™ a 2-year, and Elite Economic Guard™ a 1-year. Every cover also ships with a 30-day return window.
Do you offer free shipping and returns?
Yes — free US shipping on every cover, plus 30-day returns if the fit or fabric isn't right for your truck.
Can I use the cover indoors and outdoors?
Both. All tiers are breathable and water-resistant for garage or driveway use; for full-time outdoor or jobsite parking, ShieldAll Ultimate™ or Elite Supreme™ add UV, rain and snow protection.
