Description
When hand-tightening isn’t enough, the RAM® Hi-Torq™ Wrench delivers the extra leverage your heavy-duty D size mount demands.
Designed specifically for RAM® D size socket arms and knobs, this precision-fit wrench helps you achieve maximum clamping force — especially in cold weather, high-vibration environments, or when mounting heavy electronics like marine GPS units and fishfinders.
Originally developed for military applications where gloves and freezing conditions made manual tightening difficult, the Hi-Torq™ wrench ensures your D size mount stays locked in place when it matters most.
If you're running larger displays offshore, on rough job sites, or in commercial fleet vehicles, this tool gives you confidence your setup won’t slip.
Key Features
• Designed specifically for RAM® D size ball and socket arms
• Precision-fit design matches the D size tightening knob
• Provides additional leverage for secure, vibration-resistant tightening
• Ideal for marine, off-road, fleet, and heavy-equipment use
• Powder-coated marine-grade aluminum construction
• Made in the USA
Why You Need It
D size mounts are built for larger electronics — 10”+ chartplotters, rugged tablets, commercial GPS units, and heavy displays. But with increased weight comes increased torque demand.
The Hi-Torq™ Wrench allows you to:
• Secure heavy fishfinders and marine electronics
• Prevent movement in rough water or off-road conditions
• Tighten mounts while wearing gloves
• Lock down mounts in freezing temperatures
• Maintain position under constant vibration
It’s a simple upgrade that dramatically increases holding power.
Compatibility
• Works with all RAM® D Size (2.25” Ball) Socket Arms
• Designed for D size tightening knobs only
• Not compatible with B or C size systems
