Durable Truck Headache Rack: Protect Your Cab from Impact and Sun Damage

from

$249.99
For the heavy-duty hauler and hardworking trailer blazer, a headache rack is a must-have truck accessory. It does not take much for a two-by-four, steel pipe or other loose cargo to put a good size crack in the rear window of your truck cab, especially when you stick to the off-road trail more than the paved road. The ARIES classic headache rack offers a hardy design and sturdy structure to make sure your truck is ready to work. Made from 1″ x 2″ carbon steel tubing, ARIES classic headache racks provide excellent protection for your truck cab, from both the heat of the sun and potential impact from unsecure cargo in your truck bed. The full louvers help keep your cab cooler throughout the day, and their heavy-duty construction helps block any damage from behind. The ARIES classic headache rack also features a dual-layer E-coat and semi-gloss black powder coat finish to maintain its sleek appearance, preventing damage from rust, scratches and UV rays. Installation is quick and easy with the ARIES headache rack. It is compatible with cross-bed truck tool boxes and includes all necessary hardware for a complete installation. When your pickup truck is more than just a show horse, ARIES has you covered. We understand that it’s about more than goofing off in the mud. When you have a job to finish and a workhorse to drive, an ARIES classic headache rack is a reliable tool in your belt.

Covercraft – Cab Forward Truck Cover (Part No.C11064D4)

Cab Forward Truck Cover

from

$838.99
Cab Forward Truck Covers are designed as a quick and easy cover solution to protect your truck’s cab and hood. Sunbrella provides protection and years of service in intense sun climates like Arizona and other areas of the Sunbelt, where UV rays can rapidly degrade the paint and interior. Because of the use of acrylic fibers, which are naturally UV resistant, Sunbrella has long been the recognized leader in longwearing marine fabrics for bimini tops, sail covers and deck enclosures. Besides marine uses, Sunbrella is also used for commercial awnings due to its ability to provide UV blockage, along with a rich, woven finish. The acrylic fibers are solution dyed, before the fabric is woven, to assure the color goes all the way through the fabric. Using a special finish process, the material is then softened for use as a truck cab cover fabric. The fabric is exceptionally strong and, coupled with its UV resistance, it also makes an excellent cover for RV’s and trailers that spend extended time stored outside.

Product Features:
  • Custom Protection for Front Half of Pickup
  • Great for Use with a Camper
  • Protects Interior From UV & Reduces Heat Build-up
  • Easy to Use
  • Cab Forward Covers Available in Multiple Fabrics
