The BOSS Torsion-Flex Weight Distribution Shank offers one of the smoothest rides you'll ever encounter.

This product is a drop mount cushion shank that provides you with the option of a 16.5cm - 28cm adjustable drop, making it incredibly adaptable.

Constructed from heavy-duty steel, this shank is completed with a silver-vein powder coat.

Torsion hitches require some initial towing for a few hundred kilometres with a load to properly adjust the torsion rubbers for their intended flexibility. During assembly, we freeze the torsion rubbers to fit them into the housing. This initial towing period helps them settle in and start functioning as expected.

• Minimum towball weight for torsion hitch to work: 180kg
• Maximum towing weight: 4500kg
• Maximum rated tongue weight: 500kg
• Hitch weight: 33.2kg

What is Torsion Flex Technology?

Torsion-Flex technology is our patented design that helps improve hitch function and advantage. Its unique assembly leads to its effectiveness on the road. Once your trailer is hooked up, your tongue weight is applied, and you’re going down the road, it’s time for this hitch to shine.

In motion, the arms of the hitch will move up and down with the bumps in the road to decrease inertia between your truck and what you’re towing. An added benefit to the Torsion-Flex hitches is the built-in tongue weight scales.

Increased Cargo Protection
Since our Torsion-Flex technology moves up and down with the trailer as it goes over potholes and other road hazards, it reduces the inertia you feel between the truck and trailer while driving. This keeps your cargo from getting bumped and jostled around in transit. You can enjoy a smoother ride with the peace of mind that whatever you’re towing will arrive in one piece.

Increased Fuel Economy
This patented technology reduces inertia by up to 90%. This decrease in drag improves gas mileage. Some customers have reported saving up to 3 miles per gallon. Over time, this really adds up making it that much more clear how the Torsion-Flex technology is in a league of its own.

Reduced tire wear on truck and trailer
Due to the smoother ride and decreased inertia, tires on your truck and trailer will last longer. Anyone who spends time on the road knows that replacing tires can be expensive. Worn-out tires can be incredibly dangerous. With our technology, you can know that your tires are in good shape and not wearing out anytime soon.
