You'll want to check out this article on Overland Journal/Expedition Portal about the benefits of installing a Nitro Limited Slip Differential.

The Nitro Helix-Helical Gear Gear is a torque-sensitive mechanical limited-slip differential that uses Helix-Helical Gears and spur gears to dispense and distinguish input power between two drive wheels or front and back axles. This is a completely separate design from the common beveled spider gear designs seen in most of the automotive industry.

Just like any LSD, the Nitro Helix-Helical Gear Gear functions as a standard or open differential under normal driving conditions, allowing one wheel to spin faster or slower as necessary. When a wheel experiences a loss of traction, the gear separation forces start to take effect and distributes the torque to the high-traction wheel by increasing the helical-shaped gears mesh force until wheel spin is reduced or entirely stopped. Once the vehicle exits the low traction condition, the differential resumes normal operation.

What nice about the operation of a Nitro Helix-Helical Gear Gear LSD, is its characteristics; smooth, quiet and automatic. This LSD will engage without any driver awareness or require any action. It also has no wearable components and requires no maintenance, producing less time on the rack and more on the road.
