KIT – 4500HD for Grain Trailers – Single Arm

SKU: KIT - 4500HD G T - S A Category:


Includes New 4500 Series HD Arms and Available SMART3™ or SMART2™ Remote Upgrade.

Built Strong, To Perform in the Real World! The 4500 Series HD features a powerful American-made motor with an all-metal gearbox and incredibly reliable magnetic brake. Preassembled, heavy-duty extruded aluminum torsion arms are equipped with spiral-reinforced elbows for flexibility to move smoothly over loads.

The 4500 Series HD is available for all trailer makes and models! Its motor produces optimal rather than increased torque (which can harm your tarping system). Since no electrical energy is used to actuate the brake, there are no electrical connections to misfire. A patented pivoting motor mount allows for any misalignment of the roll tube without stress to the motor or arms.

An improved rubber boot on the flex-joint guards against damage from field and road debris. An additional flexible elbow, called the Gate Flex™ option, bypasses side- and top-mount hinges to accommodate tailgates. A protective bolt-on shroud facilitates easy motor access.

Note: Jet, Mauer, Merritt and Western trailers will be automatically charged an additional fee for backer plates to be added to the kit for mounting of the 4500 HD.

Additional Note: The ProTrap®  or AutoTrap™ Currently on Trailer question is only used to help Shur-Co® get you all the correct parts and wiring for the 4500 HD installation. Check YES for this question if not an order for the ProTrap® or AutoTrap™.

Key Features:

Heavy-Duty Front Arm
The heavy-duty arm is so strong that Shur-Co® backs it with a lifetime warranty. It come preassembled, with a super-sturdy mounting bracket that makes a backer plate unnecessary in most installs. The roller bearing-style rear arm bracket has a low-friction design that won’t wear out. Arm is inset from the side of the trailer to prevent obstruction of clearance lights.

Heavy-Duty Cable Return
The cable return is mounting on the rear of the trailer in place of a rear arm. Theis heavy-duty cable assits the front arm in rolling the tarp back-and-forth across the trailer.

Control Box w/Fully Sealed Switches
The trailer mounted control box from Shur-Co® has fully sealed control switches for better internal component protection. The design eliminates potential grime build up between switches which can cause sticking of buttons.

Magnetic Braking System
The 4500 HD’s motor produces optimal torque, not just an increase which can be detrimental to the system. The 4500 motor brakes through matched polarities, so there’s no moving parts to fail.

SMARTwire™ Sealed Wire Harness
The patented SMARTwire™ from Shur-Co® utilizes a dual 6-gauge and 4-gauge wire with automotive silicon seals at each connection. No additional wire stripping or crimping is required. Precision-machined brass pins and sockets lock the plugs together for a tight secure connection. SMARTwire™ connections also allow easy expansion for additional SMARTrailer™ accessories. You get plug-and-play convenience for your electric tarp and ProTraps, plus a 12-volt tap to supply power for your LiteALL™ LED work light package and other future add-ons.

Protective Flex Boot
Our improved flexible rubber boot, located on the flexible joint/elbow, provides protection from wear and tear due to field and road debris.

Pivoting Motor Mount
The patented pivoting motor mounting bracket offers freedom on two different axes to easily accommodate the occasional bent roll tube or uneven tarp roll. The protective bolt-on shroud provides additional motor protection from nature’s eliments.

Easy Installation
Front and rear arm assemblies come preassembled for faster and easier installation. The new heavy-duty mounting bracket accommodates most makes and models of trailers without modification and makes backer plates unnecessary. Its bolt-hole pattern matches most trailers’ rivet and rib spacing, allowing for easy installation. We even offer a bracket designed for sloped trailers.

All Wire and Hardware Included
This powerful upgrade for existing manual or electric side-to-side tarping systems is as easy to install as it is to operate. All electrical components and wire needed for installation are included.

SMART3™ or SMART2™ Remote Upgrade
Choose from both our wireless options, the patented SMART3™remote or the patented SMART2™ remote. Run the 4500 HD, plus four more 12-volt Shur-Co® accessories, with our five-channel SMART3™. It deactivates when the flip-style cover is closed or after three minutes of inactivity.
