They’ve been around for years, cheap reliable traction that is easy to install in your stock open centre. Often referred to as Lunchbox lockers, these automatic lockers consist of 2 bi-directional dog clutches which lock both axles like a spool when torque is applied and when torque is not being applied disengage to allow one wheel to turn faster than the other, which is what happens when you turn.
There are a couple of variations of the lunchbox locker on the market, and I thought I would take some time to show the differences between the old faithful Lockright from Richmond Gear and the new kid on the block the Spartan made by Yukon.
The two lockers pictured are both for solid front Hilux 2 Pinion diff.
The boxes look remarkably different, however once you pull them out of the box, they look almost identical.
Both consist of a driver, a coupler and a spacer and a bag of springs and pins. I put them on the scales and the Lockright weighs 2.1kg’s and the Spartan 2.15kgs.
The main difference between the two is the pin system. The Lockright has smaller pins and one small spring that fits inside a larger spring per pin. The Spartan has larger pins, almost double the size and one medium size spring per pin.
The way you install the pins and springs into the locker is also different, installing the springs into the Lockright you need to use a small screwdriver to seat them into the driver, whereas the Spartan comes with 4 spring retainers allowing you to push the springs into the driver and lock them in, once installed into the carrier you simply pull the retainers.
So there you have it, a basic overview of the difference between the Lockright and the Spartan Lockers.
Happy Wheeling.
