Things To Consider When Buying Lockers for Jeep JK
If you don’t have any prior experience in buying lockers for Jeep JK, it could be a bit challenging at the start as things are new, and unlike anything you have experienced before.
Analyze each and every factor given below in our guide in detail before making up your mind to buy a specific locker. Let’s see what the factors actually are.
Automatic / Selectable
Automatic lockers, as the name suggests, are the ones that engage themselves automatically whenever needed, and vice versa. They basically stay engaged since the turning on of the vehicle.
However, whenever a turn comes, they disengage themselves automatically to make the turn smooth. Automatic lockers come cheaper when compared to the selectable lockers.
Selectable lockers, on the other hand, are the ones that manually need to be engaged. They put all the pressure on the driver, and it wholly depends upon him whether he needs them engaged or not.
Traction essentially refers to the measure of grip your vehicle has on the road. This factor is critical whenever you are riding on a slippery or a muddy road where the friction is negligible.
Lockers come with a measure of traction between 40-100%. Hence, it is also an important factor when considering to buy them.
For the beginners, installation of lockers can be quite tedious. So, they should always keep in mind the ease of installation when selecting a particular locker as it varies in every model.
Automatic lockers are usually easier to install and maintain when compared to selectable lockers.
Moreover, there are some high-level models that have a further complex installation. In case you’re stuck, getting the help of a professional is always advised.
Precision basically refers to the exact amount of control your lockers are having on the vehicle. Including the time they figure out when to engage and disengage, and how accurately they can measure it.
So, never forget about checking the precision of a locker as a low precision one can almost mess up your needfully.
Maintenance plays an important part in owning almost everything in the long run. The same is the case with lockers. They also need proper care and regular check-up.
People don’t have much time on them nowadays, and finding time to take care of the lockers frequently is not the best thing to have.
So, depending upon your schedule, look for the locks which need minimal maintenance or are free of it totally.
