Description

Thunder 7000 Power Tarp System Dual Arm Mill Finish 

The Thunderstone 102745-01 is a heavy-duty, fully automatic dual-arm tarp system from the Thunder 7000 series — engineered for reliable, hassle-free tarp operation on grain trailers, dump trailers, hopper trailers, and other hauling or bulk commodity trailers. 

Key Features

• Dual-Arm Powered System — This kit includes both front and rear powered arms, delivering balanced, synchronized tarp movement. Dual-arm operation ensures even coverage and consistent tension across the entire trailer load. One-Touch™ Automatic Operation — Open or close the tarp at the push of a button. The system’s “One-Touch” technology manages start, stop, and reverse functions automatically. 

• Heavy-Duty, Weather-Resistant Construction — Built with high-strength aluminum arms (mill finish by default) and a sealed 12 V DC motor. All electrical components — including the control box and wiring harness — are water-resistant and sealed against dust, moisture, and road debris for rugged, all-weather performance. 

• Plug-and-Play Installation — Comes with mounting hardware, wiring harness, and all necessary components for easier installation or retrofit. Universal brackets allow this kit to fit a broad range of trailer makes and models. Have a Dump or Belt Trailer you will need to go with the Flex Arm Version of this System. 

• Adjustable Tension & Reliability Features — The system uses durable hinge joints and a ball-and-socket rear bushing to maintain consistent tarp tension (even in windy conditions or under load). It also includes an easy-disconnect motor setup so the system can be manually operated if needed.
