Lift Kits:
There are two main reasons for adding a lift kit: Increase your ground clearance & Increase your articulation. It's all to do with helping your vehicle cope with tall or deep obstacles. Adding a lift kit on it's own won't improve your ground clearance as it works between the body and the axles. However, once done you can fit bigger tyres and wheels helping increase the gp beneath your axles. Articulation is the amount of travel you have for each wheel between squashed up in the arch to dangling down when the shock absorber is full extended. Increasing the travel of your shocks increases your ability to keep a wheel in contact with the ground in deep ruts etc. (Link to more details to follow soon)

Protection:
These are simply tough bits of metal that you put on to protect your expensive bits! If your diff cracks on a rock, you could lose the ability to drive. If you're steering arms hit a rock and bend, your wheels could end up "toed in" so you can't move or steer. Tank and sump guards can also be fitted but the first two are much more likely to be needed! That said, if you pick the right routes and don't get carried away your standard 4x4 can still cope with a lot of terrain. (Link to more details to follow soon)

Winches:
Not a necessity, a mate with a rope will often suffice, but the can be really handy for getting yourself out of a sticky spot or recovering a stranded friend! They should be used with care however to avoid accidents. (Link to more details to follow soon)

Spot and Work Lights:
You never know when the weather might close in or a puncture take longer than expected. Work lights (flood light pattern) can be fitted to illuminate the area around your vehicle as needed. Spot lights (Driving lights) are more aimed for providing you with a well lit track in front of you. Like fog lights they aren't there to blind oncoming traffic so make sure they're wired up correctly. On a dark or unlit trail they can really make the difference between safe and unsafe visibility. They're good for shining ahead to warn oncoming traffic at hump back bridges too from personal experience! (Link to more details to follow soon)

Waffle Boards:
Usually made from fibreglass, these boards, sometimes called bridging ladders, can be used to create a path where there isn't one, across ruts or rocks, through slippy mud, even on sand to some degree but propper sand ladders are better here as they have more surface area and are less prone to sink!

Tyres:
This topic is quite subjective, but on the whole you get what you pay for. Remoulds and retreads are a lot better than they used to be but they will wear out quicker and are not designed for heavy or daily use. New tyres are more expensive but there are advntages if you want to run your vehicle day to day as well. Some offer better wear, some offer better road noise, think about what you need them for and don't just buy the biggest chunkiest you can find. Tyre choice not only affects grip but also handling, steering, performance, turning circle and life span. (Link to more details to follow soon)

CB Radios:
Often useful, and really handy now they are licence exempt, these useful radios give you 2-way communications making it easier to keep a convoy in check both on and off the road. Limited to 4 WATTS, they have a range of about a mile in closed in terrain but can reach over 15 miles in the right conditions. Amplifiers or burners are available to "beef up" your signal but beware, they are illegal and used incorrectly could fry your rig... that is blow up your radio! (Link to more details to follow soon)
