KYM Aluminum Tarp Bow Set: Upper Arm and Cross Tube

The KYM Aluminum Tarp Bow Set (T-ATBS-93) is a replacement upper bow and cross-tube assembly for front-to-back aluminum flip-arm tarp systems. Engineered for lightweight durability, this kit includes upper aluminum arms with pre-welded 90° corner connectors and an adjustable cross-tube to replace bent, cracked, or damaged top bow assemblies.

Compatible with both 4-spring and 5-spring aluminum pivot systems, it restores structural rigidity across dump bodies from 93″ to 110″ wide.
